This video is a recording of the class we taught at Midwest University 2018 called “Using Revit + IrisVR Prospect to Enable Virtual Reality Meetings.” Some of the audio is not a perfect about halfway through the class due to a misplaced microphone so we recommend turning on closed captions.

The class talks about:
– Solving real-world architecture and design problems with VR
– Using VR with Revit files + how to optimize your 3D model for the best experience in VR
– Revit to VR workflow using Prospect + Oculus Rift
– Common VR workflows for the AEC industry, including walkthroughs for design review
– Collaborating in VR with Multiuser Meetings + best practices

and Revit and this is on the heels of a release that we made about a month ago that was our 2.0 release and has the capabilities to join a meeting together in virtual reality using Revit so we'll walk you guys through the steps to go through that process and talking about some of the best practices I'm gonna start by talking about some high-level value of VR what we've seen in the industry where we see VR heading a little bit and then we'll dive into VR specifically with rather some tricks that we use for optimizing the file before going into VR common VR workflows that we've seen that our users are doing right now and then we will have a collaboration session we have our booth two employees that are gonna join us from there and we'll walk through with them and you guys can see the meeting happening across across time and space and then of course we'll do questions and answers so my background I'm the CEO and founder of iris VR I come from architecture I went to the dark side of Technology about four years ago and we started the company focusing on how we could really make VR accessible to a EC we're close specifically we've been focusing on Revit Rhyno and Sketchup how we can get a lot of that 3d data into VR very quickly really make it a seamless process and I come from a rendering background in a modeling background so I'm on the team bringing a lot of the product oriented vision and a lot of the 3d work into VR and my educational background that's interesting is actually in economics but I joined iris about a year ago on the customer experience team so I work with a lot of our customers on you know workflows and really making sure that they're getting value out of you know their VR software if you write to support at iris VR calm more info at RSV or calm or help at our SBI calm that was all go to Harry right now so he's there he's the response and so at iris we are about 25 people now we're based in New York City we have two software products we're talking today about prospect we also have a mobile product that works with mobile devices and we are focusing on how we can make we are really accessible for all these workflows and we started working in VR back in the day because first it's a true to scale experience any of you that I've tried VR it sounds like most people in this room have been in VR a couple times the sense of scale is something that you just don't get in any other medium and it's something that's very important if you're working at a building before it's built and from that that true to scale value we're seeing that it can help build trust with clients you can get a lot of buy-in with customers it can help speed up the approval process communicate design intent and one thing that we're seeing more recently is it's really helping in the QA QC process especially around verifying and validating the modeling process and especially if someone's making a messy model being able to walk through and be like this and this and this is wrong and do a really visual QA QC pass on it I know what we're talking about now is also communicating across teams and across different project stakeholders so now that you can do all this in VR why not bring other parts of your team into that experience and start having these conversations as you're immersed with different parts of your team and the end result of course is saving cost saving time increasing communication and better visuals I visualizing your project and being able to walk through the space true to scale so for that sort of for VR in general for us specifically we focused a lot on how we can make this easy there's a lot of great tools out there that give you a lot more fine-grained control of the experience but they're very technical a lot of our approach has been as VR starts expanding beyond just the tech leaders at firms how can people that are just day-to-day in Revit day-to-day and Rhyno begin to use this in a really accessible way and not feel like it's removed from their workflow so folks focusing on ease of use both on the workflow side but also on the in VR experience is a lot of what we're doing day-to-day and testing with customers that comes from our native 3d files support you'll see this with Revit as we do this walkthrough we are pulling in more than just the geometry we're getting a lot of the metadata we're getting a lot of the organization of the file the way you structure your families your components the way you structure all your layers we're trying to pull all of that as much as possible into VR so that you really feel like you're in your modeling environment when you go from one of these modeling tools into virtual reality and comfort is king anyone that's tried VR usually has an experience where they got pretty sick and that's bad you don't let your clients to get sick in VR they'll associate that with the project that's no good so a lot of the work we're doing is how do we make this always performant even with large files and then also when you're inside the experience what are the locomotion best practices what are the interface best practices that will keep people feeling grounded in the space and not sick and then now with the recent release also talking a lot more about collaboration and now that people are able to share in this experience in VR where are the new interface challenges if you're suddenly able to have a couple people in VR with you how do you guide them through the space how do you make sure they don't wander off how do you make sure that they're listening to you and all of the associated interface challenges is that we're starting to tackle and figure out what an actual in VR meeting looks like long term and we won't be here without a lot of our early partners we put some logos up here but we we've had most of our early customers are with us through beta that we were in a very early development stage from 2014 through pretty much 2017 and the last year have come to market and have been starting to distribute this technology so a lot of architecture and construction firms will be engaging with us since the beginning and helping us develop this tool so we're gonna walk through Prospect this is we're gonna showcase something that is available with a 45 day free trial we're gonna talk through some other tiers as well that we have a viewer tier that is free and we have a couple others as well but we'll show you guys the trial tier that you can get from iris we are calm slash prospect and we'll show you the full workflow through that and for this specific walkthrough I'm gonna talk about how we can optimize this file for VR so we'll go through that and Revit setting up a narrative this is something that we see a lot with client interface and with design review is how do you actually start sequencing the VR experience so someone can experience a narrative that you've planned well they're in VR how you can import those settings into our technology and then what features are available to you once you're in VR for both your own personal work and for multi-user functionality we'll also cover some tips and tricks that we found along the way alright so like I said before comfort matters this comes down a lot to your graphics card a lot of you probably know this but we're running this machine as a 1080 T @ GT X 1080 in it which is from Nvidia I never thought I'd talk about GPU so much and use acronyms and and four-digit book words but we are talking quite a lot about GPUs these days because that really decides how performant the experience will be in VR and it really drives the real time experience so starting with the GPU what matters also is the complexity of your file we're doing a lot behind the scenes and you'll see this in our engine we're doing a lot to optimize this on the fly and we do a pretty good job but if you have a massive file that is starting to bog down in Revit and it's having a hard time running on your own machine we're likely gonna have a hard time loading it into VR as well we can we can do it quickly but there's there's not too much magic behind the scenes once you get to some really messy geometry so we can talk a bit about optimizing that view and also optimizing the models and the families that you've imported and how you can detect issues before you're in VR and then a very important one is testing and retesting we oftentimes hear of VR being sort of used for the first time in front of the client how they recommend trying it first and doing a couple trial runs as you prepare for meetings as you prepare for walkthroughs and ways to test those experiences so we'll start on the optimization side when we install prospect this is what the desktop app looks like so this will install locally on your machine this isn't a cloud-based tool at this point there are some there are some web-based elements with the multi zyrtec that we'll get into but this exists on your desktop and when it installs it puts in a plugin in Revit it also puts in a plug-in in Rhino and Sketchup right now where you can go immediately into the ER before you go here though I'll show you some steps that we go through when we're setting up these experiences so the first big one and this is one that's accessible if you really want to go into optimizing for frame rate is going through 3ds max to detect face complexity of these these objects there are other open-source ways to do it that I won't get into but you can export this file bring it into blender and also start sorting by components I'll show you the 3ds max workflow though so here we are in max this might be a workflow that some of you are familiar with this is essentially linking the model you'll see it's in my links here I have the Revit file linked and then I can go into I use max primarily just for this purpose right now as we are as we're developing in Revit but I can go into max go to this list view right here and by default you'll just get the breakdown of your families and your components just by name and the trick that we have and that we've seen a lot of people use is if you right-click on this sorting bar you can go to configure columns and this will give you a list of data that you can sort by we have selected faces here so it won't show up in this list because I've already selected it but once you have faces selected you can refresh this window and then you get essentially a breakdown of polygon complexity per family in your Revit model this is really helpful if you're trying to figure out what's really causing your experience in VR to bog down you can sort this by descending order and get a list of what the troublemakers are and the number of times you have customers send his files and it's like one car that was imported by an intern or like some shrubbery made in in rabbit that's fully fully geometric usually there's a couple problem families that you can either remodel or you can remove from the experience and it will totally optimize it so I'll select these three up top because it seems significantly bigger than the others I'll click OK and then in 3ds max I can right click and isolate this view and then these are the ones in the file that are much higher density of geometry than everything else and this is a good example because if you guys know the rabbit sample file which probably a lot of you do you rarely look at these water towers and if your hum going through VR you might not need this in your walk through so if this if these were design elements that weren't necessary for the client experience this would be a great example something that you could turn off before going into Revit and then have a more streamlined experience because you have your polygons in there so I will do that actually for this demo we'll turn this off and this is just an example of something you could do that would really really automate this all right so then once you're in Revit as well before you click that view in VR button to prepare for a narrative experience we import all perspective cameras that you have from Revit so before you click that send button you want to make sure that you have sort of a nice setup for your perspective views because these are the ones that will load into VR so a best practice that we've seen quite often is in rendering of course you want to put the camera right in the core often you want to put the camera right in the corner of the room that's going to give you the best results in VR it's kind of the opposite this is an example in the living room if we show this camera this camera defaults to be like right up against this wall because if you want a nice shot of the room you're gonna be pushed up against that wall for a rendering if you are you really want to make sure you have space all around the player so as you start setting up these perspective cameras put them either in the center of the room or in a place with some movement because that way when you bring a client or another user to that space they'll feel like they'll actually have some leg room and some movement and I'll prevent them from feeling really claustrophobic so with all the cameras in this environment we've set them up so that they're a little bit more removed from the walls they're named properly they're a little clearer we've added a few more for like the bedroom here just to start adding essentially a room walkthrough that we can use and then probably most importantly especially with large files is VR really is the most imporant when geometry is under control and I think for things like a hospital wing or an airport or anything that's really spanning a lot of space the square footage it does help to set up a section box for the area that you want to specifically review you can load in entire files it will make the processing a bit longer but we have found that for the client experience and for any sort of collaboration session being able to keep folks focused on just a certain area and scope of work is is really beneficial to making the meeting go smoothly yes so all this is within Revit mm-hmm so yeah this is I just have my just like my camera I just have my section box set up here and have that turned on and this just to show that we're not faking this I'll crop this a bit more and you'll see when we bring this into VR it'll it'll load just this this sectioned area and we also this is the base so I I have set up a VR view and we see this a lot of our customers they'll have sort of either a VR sub folder or a VR section or they just name everything you know for VR you know make this for the viewer presentation and they'll have sort of their own views set up and they'll specifically also have some of their camera visibility set up in certain ways so for example if like railings on the project aren't needed for the walkthrough taking those off or turning off MEP or turning off the different elements that might not necessarily be part of the conversation in VR will will help streamline the process and then once you have this file set up once you set up your review you set up the other perspective cameras you've set up the right location of the cameras and visibility's you can finally click that VR VR button and we'll give you a window right here to choose the 3d view I have a VR master right here which is the one that we were just talking about when it's open so I'll select this and then this process is pretty fast this is just Revit sending the file into our own format so now at this point it is no longer a Revit file it exists in our ecosystem as an iris VR file if you dug into our into like app data and in the computer you'd see that it was a dot IVD so that's our own database format where we're retaining a lot of this data and sort of cueing it up for a VR experience in this window you see I'm not envy are quite yet I have a couple options I'm gonna tell it to not launch right away because I actually want to change some settings before I go into VR I'm gonna tell it to save this will save to my library and this is z-fighting this is if two faces are overlapping though flash in VR and it's actually really not as a ting because it'll flash differently in each eye you're just like instantly sick so that's pretty important to fix and this is our pass we'll do some testing on it and make sure that it doesn't it doesn't overlap and offset it a little bit so I'll usually keep this on for edit files because it often has a lot of overlapping geometry so we'll click start processing and at this point this takes a couple more seconds it'll save it to the library so here's our library I obviously just have one file loaded that's this one for this demo that we're giving typically you'd have a lot more in here and at this point you can click view and VR which would send you into a solo VR experience this work in the oculus or the vive or you could schedule a meeting and and have other people will join you in it and we'll show you the scheduling the meeting and going in there because we can also show you a lot of the solo experience within that meeting experience before I do that this is something that a lot of people don't see because I think everyone's just sort of eager to go into VR so they click that button right away it's a good opportunity for us to share with you guys some of the other features that we have in the file settings before you enter VR so this viewpoint tab here is associated profile so once you have a file selected in your library you can go into viewpoints and these are the cameras that we set up in Revit right so you can see these came through they're all turned on and this is again sort of setting up your your narrative sequence so these have numbers next to them this is the sequence you'll walk through in VR and I know that for example the solar analysis can be turned off the section perspective can be turned off this view can be turned off and I'm turning all those off because those will leave the user floating in space like a couple hundred feet above the ground and that's a terrible experience and a lot of people really panic when they see that so I'm picking views where people are really grounded on a certain plane and really feel like they're in yeah yes so it brings them in as ordered in Revit but we do have this UI so you can start rearranging it and like I know that we probably want to start in the yard we probably want to go to the kitchen next and then go into the living room and then I won't change the rest but you can start rearranging these we also furred most files I mean this is a very clean file obviously we know that for most files there's hundreds of these so you can just turn them all off using that master button and then selectively turn on the ones that you want that's usually how it's used or you can search for view points if you actually do have hundreds which probably most of you guys do also as you get into this there are some power user options these are transition options so you'll see this in VR but as we move people between these viewpoints you can decide if you want it to be a very quick hop or if you want it to be like an ease and an ease out fade and these are things that you can play around with you'll see when we're in VR we have set it to fade so there will be a nice fade in and fade out as you go between these these views and then the last thing to highlight here is we have a few display settings we focused a lot on design review and coordination so we've done a little less on the rendering side there are other tools that are excellent renders we're focusing on really what the schematic look and feel is and how do we make that really data rich and one piece of that that is really impactful in this experience is turning on outlines that will give you a nice schematic view within Revit and then we also do detect what classes and give it a bit of shine and and change around the the look and feel a bit and then the last piece here we're in the u.s. let's change it to Imperial so that our measuring tool will be proper and that will be set up to go so now when you want to create a meeting out of this you can go over to our meetings tab this is what just came out for us and 2.0 and this is pretty much inspired from GoToMeeting or zoom the idea that you have your existing project library and then when you want to schedule a meeting you go into this meetings tab you click create a meeting and then you can pick from your library whatever file you want to have that meeting in and then give this meeting a name so I'm gonna call this test because we actually have our colleagues joining us on another meeting that's already preset that's the same file so I'll just show you this workflow though so we can click Next there's my beautiful meeting setup and then the steps right now the way meetings work is what we're sending online is essentially player location and voice chat we're not sending model geometry that's that's both for security and it's also just from a technical perspective it's easier to let you guys decide how you distribute those files so once you schedule this meeting you'll get this format which is a dot IVM and you'll be able to export this save it anywhere you want on your computer and then when this is saved out you can put this on your own you know your internal firm's file system or put it on box if we don't we transfer and when you invite people to the meeting just attach a link to this file and they'll be able to drag and drop that file and it will instantly join them in the meeting so we'll show you right at the end how you can do that sort of as a viewer tear so you won't need an account you can just go and put that file and and join the meeting together so we'll walk you guys through that right at the end and now this meeting is scheduled so this is essentially the the meeting experience this is the class when we set up that our colleagues are in so I'm gonna go into this one it's the exact same file you'll see that we are in here together and here they are waiting for us so I'm in this meetings tab I've selected this meeting I have a few other options here but the one that really matters is this participants tab this shows you who else is already in the session so we have two other folks in the session right now and you can also change your display name because you'll have a little name tag on you in VR so you can change what your name is there if you're sharing them on a couple different people I'm gonna keep it to shame and anything else up side here do you think I think I got it ok great so we'll click meet VR before I do that I'll make sure the oculus is on that's an important step so once you launch it yard it'll just show this quick loading window don't pop in to the Ming and it's you know our colleagues who are in the other room but in theory could be anywhere in the world so you can have up to 12 people in your meeting and they're all connected via voice chat and you can see there movement so you can see they're waving and if you're pointing and so we'll kind of get more into the multi user functionality in a second but for now let's kind of discuss this mode that you get launched into when you start your yard so we can kind of see the model you know scale down we call this scale a lot of let me to also hear us refer to with my dollhouse mode but it gives you a really great kind of macro look into your model especially you know useful if you're looking at a larger area or a like a larger file we have a ton of really great people that are available here something we'll focus on are what we call our modify tools so my cheese menu he's going to click on that model interactions have we have two options we have a modified model and a modified section so modify models is gonna allow you to do just that you can move your model around closer to you and make it bigger and you can also rotate it so this is great for kind of you know looking at those larger scale detail especially if you're one yellow out of this project kind of great look at that you can also section your model in any orientation so once you click modify section doesn't know you know for that section plane you can rotate that vertically horizontally or in any direction that you're not really just by rotating your controller so say we're working on like a larger skyscraper or maybe a stadium this is a really great way to set up your model for actually navigating into it so one other quick tool that we're going to have a lot of this scale model of is unthankful so we actually pull name the geolocation love the model from whatever 3d modeling software you're using and then use that to create accurate Sun lighting and shadows based on the time of day and time ago this is really great for doing shadow studies and we are not changing the changes the time of day it instantly reflects in the bottom and so this is just a really quick and easy way to do that rather than you know manually doing that from Revit so now that means kind of went through those tools you'll see there are a few others but early level we're we're actually go through those in VR so when you implement you pull the trigger we are teleported into a load where we're navigating the pendulum we see there are a few annotations from under affecting the board but now we're turning this over navigate basically throughout any of my three menus here the popular therapy scream talk so this is basically going to bring out a great dating all of that touch doesn't image file just going to save to desktop for sharing either and up there in there yeah or even talk with somebody who doesn't necessarily have all of this be our Hardware show them we also have a great 2016 Patrick functionality so you might later with rendering out freezing you're right we're give me on this is a really great way after those cameras in one click and you can upload those to all these phone service for game sharing or any other room you don't met that they can want to view those panoramas which is again great for somebody who doesn't necessarily have all of this hardware they can kind of take a look at a static you know few point and Rohde all around so really great way to do that the next element that's on that menu is the inspect element tool so this is actually gonna pull in a lot of that data from reddit so we can actually point at any element and select it see the dome light and then on our menu we're actually gonna see a lot of that bit right losing is gonna look at this please see the element later that's on materials and also who is selected by so if somebody else in defeating it selected the specific element we would see their name there and they should yes I think they might have their computer muted but we actually do a voice chat and headphones so you can hear each other – we just muted during conferences because there's so much ambient noise but they typically because all these devices have have headphones you do get voice chat and audio as well oh yeah and they ten years it looks like they're doing this there you go once we're in this inspect element pool we can also use it to turn off the layer that the elements on so say we had selected like a door or something we're going to turn that off our layer will show up there and you come back to turn all that off so all the furniture another big wading pool is like so what's it's like but more importantly it'll allow us to get some really great board flow tools after we exit the are will actually be able to export a list of all of our flight elements as well as their reddit element IDs and who they were flight by drinks it really easy to use that select by ID option in Bremen to jump to those elements saving me found with the clash or like a you know design issue that needs to be fixed that makes it easy to kind of jump back there moving on to the next tool you see there that little pencil icon is actually our markup an annotation tool so there are two main options available here there's a brush tool and a call-out tool if we go to the brush tool we can actually use that to me freehand annotations you know mark things up in either a handheld or a projected boat so in handheld mode you're just drawing in 3d in front of you or wherever you are you know say you wanted to use this to denote where you know certain folders will go furniture you can use them in different colors to denote different things so you know maybe you assign certain colors to certain types of things that you want to showcase you can also either than a projected mode in which case it will actually snap to whatever services pointing on so that's really great for you know checking out those windows those look good we also recently had an annotation smoothing so now everything automatically becomes so much more great for it'll just basically do that in like a circular format so you're not pretty hand drawing notes or just circles then you can modify the size of fitness board and draw on occasions that way and then of course you can also erase any of those or undo them and then you can capture these annotations using that screenshot tool they're also available to any other participant in your meetings so if you know with other participants of the meeting were making annotations we would see that and they'll see those changes reflect on there as well yeah there you go you got scared and erased it but it was good thank you the next tool that we see there is that sub settings tool that we looked at in scale model mode kind of work the same way here or actually started the measuring tool that's the throw that one so you can obviously measure all of these distances in Revit but having this measuring tool in VR is a really great way to confirm the scale of certain things so maybe we're not quite sure if this like hallway is wide enough we can use the measuring tool to really quickly get you know on measurements either the perpendicular distance between those two planes or we can also draw just like a pretty hand measurement of anything that we want especially if somebody gives it may be a familiar with the model or the client is really great to have confirm those businesses so now for real the next rule is is that that still works the same way so you can just kind of change the time of day and you'll see those shadows reflects so the next one we see their display settings same kind of talked a bit about this in the March library you can prove that these but also switch them on the fly so perfect so let's look at that next tool on the tool pallet the layers tool this is kind of similar to what we looked at in the element inspection this is a list of all the layers were brought in from credit and so we can use this to turn through comes off we can do a lot of turn off that this also works with all of your other 3d modeling software so we'll bring these in from right now to catch up so you can get your layers there so like in this example the ceiling is for not because me come into the house the next one we have if you want submissive you know what we were managing in our project library and so we have a really great way to navigate throughout specific points in the model this is a pretty small house so not necessarily as impactful but if you're working with an especially large model this is really useful for highlighting specific parts of the model that you want to work you want to put the top there's also a toggle but then bring the other users along so that's really great for our meeting actually and bring everybody to the same location like now let's bring them up let's yeah that's let's bring them back let's go to let's go to the kitchen so you'll see on screen and everybody's now in the same location we can continue our productive they were they were intensifying there's a just rest you can actually have like smooth movement up and down so change can move up and down within the model perfect so the next menu that you'll see there is the participant I'm gonna jump in one one more time with the viewpoints this is the order that we sequence them before we were dragging them around and so you can go through them here in this menu or you can use the arrow keys on the keyboard so there's a couple different ways to progress through these different viewpoints and that's part of the narrative that we're talking about is you can both in VR walk through these different areas or you can do it and let's get to the ground again or you can do it on the computer as well before we join the meeting but we see a list of all of our participants up to 12 and we have these gather and go to so gather is basically gonna bring everybody to the same point to grab kind of similar to viewpoints but maybe you're somewhere in the model that you haven't you know pre-selected you can gather everybody there and you can also go to specific you so if somebody was at a different point in the model we could use we go to functionality to really quickly jump there and kind of see what that person was looking at are talking about so again it really looks great rid of that before in a 30-day so those are some of the functions that are available AVR another really great tool that we have is actually some desktop controls that are available you can look down here at the bottom right corner there's a little button if I click on that I'm gonna see kind of a miniature version of the menu the chain has on his controller on my desktop this is a really great option for having some limited control over what's happening in VR especially you know if you have a client who isn't super comfortable with it forever VR you can actually just put them in the headset and control a lot of aspects of the experience for them from your desktop so for example if I click on this view points button right here I see the same view points menu that Shane has on his display and I can actually jumped on all of the users in the meeting Chuy's view points this way changes still look around he had set but I can kind of control the experience the other options we have available here you have some settings those display settings layers viewpoints of course participants and scale-model globe so this is a really great way to kind of control the experience for like a client that's maybe not as comfortable using the controller's themselves great so I think that's the main features we wanted to show you the new VR but now that we black slow rate elements you can actually take a look here our project library right of all of the elements of chain Flags so you'll see there's the date that elements happened we have all of those Revit element IDs there's a bunch of export report that's actually going to export a CSV list of all of those element IDs so you can just copy and paste those over to Reddit and it'll jump you and select those they got for year which makes it great for kind of sharing with your team in this bitch Shayne is the one who'd like all of these elements but if you had other participants in the meeting say applying or a project manager you would also tell you who's lying them so you can associate that to visit action items this is everything that we wanted to showcase with the press bribery right any questions on the PR stuff for you yeah so the workflow would be you can you can select that individual wall and you could flag it and then you get that list here this this flagged element was like the first step for us really offering element interaction like now we have each of these elements loaded into VR discreetly and we're starting to talk a lot about like what next can we do to enhance that integration but the first step is really just being able to tag them and be like this there's an arrow here mark it up take a picture and then have it flagged so yeah you can do walls for us yeah yes yes absolutely so that's coming we are at 2.0 point 1 as a software right now around 2.2 or 2.3 you'll have most of your BIM data from Revit in there and then a little bit after that you're gonna be able to customize which data you pull through because the full the full parameters from BIM families are insane and we're listing all those out right now and we're gonna allow you to select which ones you can display in that inspect tool yeah absolutely so that's as we've done a lot of research in this a lot of folks are requesting that like yes we can get sort of the default Revit parameters out but they would also like the customizable parameters and be able to decide which ones are fold through that's a lot of the reason some of you guys might have caught this our file format is a database format and we've built it in a way that a lot of the parametric elements of VR can really be flexible so we are tied to a specific format or formatting for these formats we can really be much more flexible and how we display that data in VR which is a lot of what we're working on this year next so if you quick slide right here so in terms of the setup setup it's pretty easy as long as you have tested kind of like we talked about there for it so one thing to know is each participant doesn't need their own VR capable computer so one of these machines is really only capable of powering one VR headset just because of the processing power required to run that type of experience so you'll just want to make sure that everybody that you're inviting to your meeting has that Hardware ready you'll also want to just test joining the meeting on each of those machines just so you can make sure that the network configuration is right sometimes especially in a corporate environment you'll have if you have certain firewall setup or proxies and we can give you all of the information that you need to make sure that those were properly set up to a lot of that connection you don't want to make sure that everybody has a headset with microphones and headphones so most of them have to pedal microphone built-in and these models head so they're also have headphones built-in but if you have anybody joining with an HTC vive it's possible that they don't have an audio strap in which means they could just plug in any set of regular headphones but it's something to keep in mind before they even go often have sessions where people aren't quite sure if there's going to be audio or not so it's something to keep in mind yeah and then also just sending those set of instructions and files well in advance of the meeting just that everybody can have them download them and make sure that they're set up so there's a Scrabble right before every day some quick notes on meeting etiquette we do a log and prospect to make sure that you know the meeting runs smoothly and everything is working properly but as in real life there are some you know thoughts to have in mind one is personal space so not teleporting directly onto other participants or too close to them just because when you're in VR you know feels very real and so having that boundary is kind of important I resist the temptation it's very tempting to like when you have your colleagues in there to like start screwing with them there is a personal space problem in VR and you got to leave a boundary for them in terms of getting started I did we went through a lot of content today a lot of this is available on our website at a 45 day trial of prospect and tested out with your own models which is really kind of the best way to see you know what type of VR work one would work for you even if we can open up your questions now and then we'll keep this running after questions to you guys to try it as well yeah we do yeah we we do it's it really does come down the GPU and we found a few machines that run pretty reliably most of them are gaming machines and the good news is that's a lot cheaper than workstation counterparts this machine's about 2,300 dollars and it really is probably the best best machine for VR right now based on weight and speed but we have a link in our knowledgebase actually if you just search like iris VR recommended machine the first article is our we keep that updated and we recommend computer hardware there and we have some desktop links as well as well as the laptops yeah on the polygon side I don't have a great I don't have a satisfying answer for you because the game engines that we're leveraging treat sort of polygon complexity very differently than Revit does a great example is like any sort of components or families and any of these 3d tools that are repeating the the tools themselves don't count that towards any sort of polygon count so if you're looking at file size or if you're looking at polygon complexity if you have a lot of repeating elements that won't really show through in Revit file or your schedule file or I know file in VR that really matters so it's it's sort of hard to gauge yes absolutely and for us for a 1080 we can get between like five and ten million polygons it's a there's there's lots of nuances and a lot of exceptions to that but in general if it's like under 300 or 400 megabytes you're gonna have no problem if it's above that you might start needing to section out your your file and then you asked about the graphics to we're pulling in Revit realistic materials right now which is why it looks very different than the shaded view and we also don't currently have any RPC content so RPC contents on the roadmap and then in terms of how we display the graphics from Revit specifically we are working on supporting shaded view all the hatch patterns the surface patterns and then realistic view allowing you to switch between those and also turning on and off ambient occlusion so all those combined over the next couple releases you'll start seeing that really reflecting the layer of file looks in your editor itself yeah that is a very timely question we are likely going to have it up either on Trello or one of those roadmap boards pretty soon we don't have a public road map right now we are absorbing in feature requests as much as we can so like please write to us if you guys have specific requests it will go directly to the two of us and I'm doing a lot of 2018 and 2019 roadmap planning right now so part of that is getting a lot of the most common request live because we do get a lot of repeat comments that are already mapped and that will make a big push around that one that's live but we're gonna have some public board pretty soon Oh to give you an idea we are tethering our phone right now because that Wi-Fi and the yeah yeah and it so we can actually we've done some bandwidth testing because it's primarily the location which is just an X Y Z access of the player and then some voice data it can almost run a dial-up it's really low network requirements if you I don't recommend high up but it's close but it is very limited the bigger issues with large firms is they have firewall firewalls against gaming connections and this is gaming technology so we have some ports that we recommend opening for multi sir yeah and that's that's in our knowledge base as well that's also a Google and that's also something that we post on Twitter and tweet about quite a bit as we really small the user great well thank you guys so much this is a great thank you for the attention and we'll keep this running so if you have questions afterwards and want to try this out you can try it here and then you can also try to booth during during the happy hour tonight so we'll have it running then – yeah exactly [Applause]
