Scale Model Mode Update: Section, Scale, and Rotate

Here at IrisVR, we’re regularly prototyping the in-VR user experience as we design our software. In order to create useful and intuitive virtual tools, we often think about the end-to-end process of how a spatial concept develops into a completed building project. This includes the process of making physical scale models, which are effective at communicating complex space but are time consuming to keep up with iterative design changes.

In our latest update to Prospect, we reimagined our virtual equivalent of the physical model - Scale Model Mode - and enhanced its capabilities.

What is Scale Model Mode?

Scale Model Mode lets you view a virtual rendering of your model in the same way that you would view a traditional, physical model.

You can lift and move the scale model around space...

...zoom in on your model...

...and rotate.

Additionally, as part of our latest release, you can now section your model! This allows you to view your model from new perspectives and teleport directly into interior spaces (especially useful for large, multi-story projects).

You can section the model vertically...



...or however you’d like!

It’s our goal to create tools that are easy to use, fit into your existing workflow, and make it easy for you to iterate upon your ideas. Want to learn more? Read our release notes for full details on our latest update.

Behind the Scenes at IrisVR: Designing VR Software

With our latest update to Prospect I wanted to share our design process with you, our users, because your involvement is so essential to the evolution of our software.

Designing virtual reality software often requires approaches, tools and ways of testing that are different from traditional software development. At IrisVR we have an incredible team of researchers, designers, prototypers and developers to meet these challenges. As we tackle new problems, we use the steps outlined below to guide our design process and to find the most effective and powerful solutions.

Our users come from all types of backgrounds. There are people using VR to look at houses, skyscrapers, furniture, cars, shoes, toys, construction sites, data visualization, and so much more. We have 3D software professionals and amateurs, VR veterans and first timers. They work all over the world and work in companies of all sizes. It’s crucial that we consider all of them and set up a process that listens to their needs first.

1. Listen

Concentrate on the Users.
What are the tools our customers are requesting? What would make their workflow smoother and save them time? What will help them to design, create and communicate their vision? Recently, users expressed interest in ‘zooming in’ to their model, but what do they actually want? Why would this be useful and where would it be the most helpful?


2. Learn

Try Everything. 
Familiarity with the VR space is critical. We play video games in VR, on mobile and on console platforms. We test out design, productivity and creative software suites. Our belief is that every experience, from a clunky interface to a simple mobile app can be helpful in improving our way of thinking. We observe the world around us to see what people do and how they do it.  We have fun, document it, and refer to the lessons we learned throughout our design and development process. We learned that ‘zooming in’ on a screen may mean something very different in virtual reality.

3. Imagine

Consider a Variety of Unique Solutions.
We make sure to document and sketch every possible solution we can come up with that relates to the problem. It’s especially important to document solutions that may seem overly ambitious, or even impossible.


4. Experiment

Make Something.
We have to jump in and start somewhere. It’s time to dive in and make something simple and quick. If we are going to be designing an object, an interaction, a menu, a scene, a control, we have to start by seeing some element of it in virtual reality. It’s already time to add more ideas to the ‘Imagine’ list. We can also break down some of our early assumptions. It seemed obvious that objects in virtual reality should have gravity. But we were surprised what happened when they did. It turns out people really like to throw stuff in VR...

5. Iterate

Build It.
This is my favorite part. A lot of quick variations are made and tried. These are not full solutions, but we start to find the puzzle pieces that can be assembled later. There are easily more than 20 ways to simply ‘pick up’ an object in virtual reality. Some of them restrict direction, others allow rotation or remove gravity. We made a virtual room full of options and dove into virtual reality to try them out.

6. Prototype

Clean It Up.
This is where we consolidate the most successful aspects of our ideas so far. Based on tests, feedback and observations, we narrow down the iterations to a few refined prototypes. These are prototypes that can be shown to people outside the company and are testing more than one interaction at a time. We often find that the prototypes end up having their own advantages for different users. Designers who use Rhino, Construction professionals who use Revit and Architects using SketchUp all may prefer slightly different tools and features. It’s our job to then refine the prototypes even more to accommodate each user. 


7. Test

Let people break it.
There is a constant stream of users in our office who test out different features and give us helpful feedback. They try existing options, new prototypes, and we let them do the talking. There are instructions and questions, but at the end of the day our guests usually have more than enough to say on their own. We push them to be honest and to make suggestions. More often than not, they think of things that didn’t even occur to us. Throwing things in virtual reality may be fun, but people usually want their stuff back.

8. All Done!

Just kidding.
Based on the feedback, the prototypes and our own expertise, it is time to make some important decisions and move forward. The feedback will determine if we explore a new set of ideas or refine and re-test. Maybe, just maybe, there is a feature that is ready to be built and shared. 

With the release of our new tools that allow you to translate, rotate and scale your model, we found the solution was a combination of existing solutions and new approaches. With every feature we look forward to the user feedback that helps make each tool even more valuable.

In the end, this is just a piece of the process that allows us to design and develop great software for designers, architects, engineers, construction professionals and more. User feedback is the catalyst for each improvement to our software and we ask you to send any ideas, feedback, requests or questions directly to

IrisVR Case Study: From Wow to Workflow

Based in Houston, Texas, the Engineers Without Borders-Johnson Space Center Chapter (EWB-JSC) is designing and implementing a water and sewer system and biogas digester installation at the Giika Orphan Rescue Center site in Giika, Kenya. The rescue center is home for about 30 teenage boys who were previously homeless due to their families not having the resources to support them. The EWB chapter was founded in 2005 and is one of the oldest in the organization which itself goes back to 2002.

To develop the biogas digester system EWB-JSC partnered with the JSC Sustainability Officeand the Longhorn Project, a Houston area vocational agricultural non-profit. Each group is using the project to explore a different application: EWB-JSC is interested in the technology for its work in Kenya, the Longhorn Project for local education, and NASA for potential applications on Mars. In Spring 2016 NASA awarded an innovation grant to the Sustainability Office to further the partnership’s mutually beneficial work. EWB-JSC provides the design engineering while the Longhorn Project provides the cattle and facilities. EWB-JSC designs both the Kenyan digester array and the space analog digester for Mars mission design.

“VR helps us to fully understand our design and to evolve it. It’s one thing to see it on screen; it’s another to “stand” next to it.”
— James (Jake) Mireles, EWB-JSC Chapter President

Designing with Virtual Reality

The Team at IrisVR spoke with James (Jake) Mireles, EWB-JSC Chapter President to learn more about the design and the role virtual reality was playing in EWB-JSC’s work at the Giika Orphan Rescue Center. 

Q: Could you explain the role of a biogas digester?

A biogas digester takes cow or other animal manure and mixes it into a slurry that is kept in a closed container at a consistent temperature—about the temperature of a cow intestine. Keeping the mixture in a closed container enables the anaerobic bacteria present to continue digesting the manure over time. The digestion process generates methane gas and fertilizer effluent. Biogas digesters are common in third world countries where the methane they generate is used for cooking and the liquid effluent is used to help fertilize crops. NASA is interested in methane production for cooking and also as a rocket propellant and in the effluent for fertilizer.

For example, in the picture above, there is a small farmyard behind the building which will supply manure to the digester which is located downhill. The resulting methane gas will be piped back uphill to the buildings for fuel and the effluent will be sent further downhill to crops and a fish farm. 

Q: What was it like to integrate virtual reality into the project?

We built a 3D CAD model entirely in SketchUp and then used IrisVR Prospect to render the model in VR using the HTC Vive.  We then used Prospect to study the model in the VR environment for design review, which allows us to more fully evaluate, then refine the design. 

We went from “wow to workflow”—from a simple show-and-tell to a full-fledged design review—very quickly, with team members suggesting improvements based on their view in the VR environment. IrisVR enabled our team to fully immerse in the design and get a sense of the scale of the array as well as its technical operation. We figured out many improvements that would not have been discoverable without VR. 

Q: How did you use virtual reality to communicate the vision for the project?

Outside of our team, we presented the design twice to the Johnson Space Center community. The first presentation was at our September [EWB-JSC] Chapter meeting and the second at an Innovation Days event held in early November 2016. 

We had 260 visitors stop by the Innovation Days event, including senior Johnson Space Center senior management. Our presentation received the 2nd place “People’s Choice” award out of 36 presentations on various technological innovations.

Q: How has the engagement and reaction been in comparison to other meetings without VR?

The proof of its impact on our clients was the recognition we received at the November Johnson Space Center presentation. We have been invited to make a presentation to Johnson Space Center senior staff in January 2017, directly as a result of using IrisVR.

“When I set up the VR walkthrough, I thought we would spend maybe 15 minutes to half an hour total. After about 15 minutes the team moved past “wow” and started working on the design. The session turned into a full-blown design review lasting two hours.”
— James (Jake) Mireles, EWB-JSC Chapter President

Workflow & VR Hardware Setup

The EWB-JSC team created a virtual reality experience of their project by modeling all the components in SketchUp, then dragging and dropping their file into IrisVR Prospect and using the HTC Vive headset to explore. Here’s how they did it:

First, create your content: The model was built entirely in SketchUp in two parts - one was the digester design and other was the environment which included the campus, buildings, and terrain. The refined integrated model was then imported into Prospect.

Second, setup your VR headset and station: The team uses the HTC Vive to create a room-scale VR setup using camera light tripods to place the trackers. The complete rig is mobile and transports in a rolling hard shell toolbox purchased at a hardware store.

“Room-scale VR is far superior and Prospect’s “teleportation” technique ensured that no one experienced simulation sickness. The team worked in the VR for two hours with no ill effects felt by anyone.”

Adding Virtual Reality to Your Workflow

Virtual reality is not a tool of the future, but a tool available to designers today. Incorporating VR as an asset to your project really is just as simple as seen in Miele's workflow above. All that you need to get started are four components:

1. 3D Model of your design

2. VR Headset (HTC Vive or Oculus Rift)

3. Computer that meets hardware requirements for VR

4. IrisVR Prospect installed on your machine

Enhancing Storytelling for Architecture

Presenting your project using Virtual Reality

At Iris, we are actively developing support for presentations to allow architects to tell the stories of the buildings they design in the most effective way. To do that, we have released Viewpoints, a new tool for Prospect. We like to think of Viewpoints as the chapters in the building’s story. Our objective is to help the designer narrate their vision while the client interacts with the space through a 360° degree view. 

Each architecture proposal is the result of a series of decisions made by the designer. This set of deliberate choices shapes the space that is meant to best represent the core values of the individual, the family, the community or the organization that requested the services. As an architect, the designer’s role is to take and abstract the principles shared by the client and to analyze the context in which the building will be constructed to create a new and unique entity. As a result, the story of the building is an elaboration of the client’s narrative, a more developed version of events using the building itself as the medium. Naturally, the architect is the narrator.

The story of a building

The story of a building

Storytelling in Architecture is highly complex. The first step is creatively addressing both the client’s explicit requirements and their dreams for the new environment. This is followed by meetings meant to get the client engaged in the process by presenting how their aspirations will be possible thanks to the form, structure, and materiality of the new space-to-be. To fully convey the message, it is key to travel through a series of crafted moments showcasing the expected behavior inside and outside the projected building. Sharing points of view and perspectives in a clear sequence is a fundamental part of the process. As a designer, you can now do this easily using Virtual Reality.

How to Create & Curate Your Presentation in Virtual Reality

Prospect integrates seamlessly with the existing design flow in Revit, SketchUp, Rhino, and Grasshopper. 3D Views, Scenes, and Named Views are already being used for documentation and rendering in each of the authoring tools just mentioned. Each of these experiences is then collected and displayed in the Prospect Library

The following steps describe how to curate the presentation to enhance your story. 

Prepare your presentation

1. Click on View in VR in the toolbar (for Revit and Rhino files) or click on Import in the Library (for SketchUp files).

View in VR button in the Revit toolbar

3. Click on Start Processing for VR and close the dialog window once the file has been saved.

4. Select the row that holds the newly added file. On the drawer menu that you can find on the right side of the Prospect Library, you can select/deselect Viewpoints. More detailed screenshots of Viewpoints can be found here.

  • Choose to make active only the Viewpoints that are pertinent to your meeting. This menu will always be available to you, so you can select different Viewpoints for other presentations as necessary.
  • If you would like to search Viewpoints by name, you can do so by using the search bar at the top.
  • Viewpoints can be reorganized by dragging and dropping.
  • The name of each Viewpoint can also be updated. Once in Virtual Reality, a tag with the viewpoint name will be shown every time you transition into that Viewpoint.

Present your project

1. Start your presentation by clicking on the Launch button located in the same row as your saved experience in the Prospect Library.
2. Help your client put on the HTC Vive or the Oculus Rift headset
3. Use the arrow keys on your keyboard to move through the Viewpoints in the same order you prepared in the Prospect Library.


4. To ensure your client is focused on the correct space in every Viewpoint, you can choose to let them view the experience without holding the controllers. This will avoid distractions, as they will not be able to teleport in the model.

Tips for a successful presentation

  • Select 5 to 10 Viewpoints for your presentation. Keep it concise.

  • Choose carefully the order in which the Viewpoints will be presented and the distance or visual relationship between the objects in each location to ensure your client understands the connection between spaces as you walk her through the project.

  • Rehearse the pace by walking a colleague through your experience. Just like in any other type of presentation, you want to make sure that you the client will have enough time at each Viewpoint to recognize the space being discussed.

  • Explain to your client the process of how you will move them through your presentation by “jumping” them from one space to the next. 

  • Running behind or out of time? Take advantage of Prospect’s white-model mode and outlines settings. Consider starting your presentation using a more abstract approach by disabling the materials (use M on the keyboard) and showing the edges (O on the keyboard) to then turning on the material textures and colors of your project.

IrisVR Case Study: Miele


Miele is a globally recognized company founded in 1899 focusing on the manufacturing of multi-award winning, high-end home appliances as well as world renowned cleaning and clinical sterilization machines. Last year, Miele’s Australian branch began using IrisVR Prospect to visualize their event and trade show designs for upcoming installations. 

Large trade show events are highly coordinated behind the scenes choreographies of booth assemblies occurring within compressed timelines. Typically exhibitors are given 24-48 hours prior to the commencement of the show to have their exhibit constructed. All aspects of the design must be thoroughly examined and prepared to precision to avoid costly last minute revisions or an unsuccessful booth.

“VR is providing significant cost savings and workflow efficiencies, but is also providing a tangible productivity benefit in that it’s speeding up the approval process.”
— Kym Porter, National Merchandising Manager Miele AU


Leveraging Virtual Reality for Trade Show Design

To tackle the many challenges of trade show design in the most effective way, the Miele design team created a virtual reality walkthrough of the installation by first modeling all the components in Sketchup, then dragging and dropping their files into IrisVR Prospect. Prospect, is IrisVR's Windows-based standalone platform which allows for native Sketchup, Revit, OBJ and Rhino files to be imported and quickly converted into virtual reality experiences, using the HTC Vive or Oculus Rift.

Creating virtual reality walkthroughs allows the team to engage all the team members and facilitate conversations around the built space. Establishing a way for the executive team members to provide constructive feedback without the need to understand how to read 2D architectural drawings. 

It also helped the team cut down on costs by eliminating the need to build physical mock-ups that quickly become outdated. As designers made changes to the 3D model, they could quickly recreate the virtual reality experience in just one click.

With every VR walkthrough, the team was able to evaluate product and brand placement, and marketing hotspots from the view of an attendee prior to its construction. Adding a clear sense of the space and trust in the final product. 

“This test case also revealed unexpected benefits,
such as space and dimensional issues as well as
highlighting optimal branding and marketing
— Kym Porter, National Merchandising Manager Miele AU
