2018 Updates

Our VR research group continues work on UniCAVE and a top priority upcoming for us will be to handle the deprecation of the NetworkView component. Look for an updated version of UniCAVE for 2018 to come out in the near future that will have this problem solved, along with some additional features and example scenes.

Work in Progress

A general update – the UniCAVE group is continuing to work on things behind the scenes, even though there haven’t been a huge number of commits, etc. lately. We are nearing the workings of a solution for Unity’s newer VideoPlayer component such that video will sync across CAVEs and other immersive display systems. In addition, we are working through a warp + blend solution that is nearing a working example case here at our lab. Both of these things will most likely be pushed to the repo in the future, with the VideoPlayer adjustments sooner. We also wanted to say a general thanks for the interest and questions we continue to receive about the project.

Stereo Clarifications

Those of you trying to work with DirectX stereo via the “Stereo Display non-head mounted” option, see requirements within the Unity documentation at this link:

https://docs.unity3d.com/Manual/StereoscopicRendering.html

Also – I have confirmed an issue that I have heard of from some users regarding multiple displays and the above mentioned stereo option – here is an official issue within Unity’s issue tracker regarding it:

https://issuetracker.unity3d.com/issues/stereo-display-vr-does-not-render-on-multiple-displays

I’ve locally confirmed that this happens on a new power wall we’re setting up – potential work-arounds until this is resolved:

– Try an OpenGL build with DLL injection
– For those using Quadro cards – use nVidia’s Mosaic mode to create a single display
– Attempt to use a different stereo technique (Side by Side, Top / Bottom) if your hardware supports this.

Cheers!

Fullscreen Issues

A user sent this link out regarding possible fullscreen issues that can occur in Unity – this could be helpful for some who are running into related issues. It appears “Reseting” the Player Settings may be a solution – as well as unchecking a Force D3D Exclusive mode checkbox.

In addition, with the latest version of Unity 2017.2, our previous tile-based Linux display needed to have it’s -screen-fullscreen flag turned from off (0) to on (1), to correctly render top-bottom stereo on a 20 panel display system (in this case the top bottom displays had to also be swapped on the prefab, but this was seemingly due to Linux desktop layout).

New UniCAVE Forum

We’ve created a forum for UniCAVE users located here:

https://groups.google.com/forum/#!forum/unicave

Feel free to post thoughts, recommendations, bugs, questions etc. here – the idea is it will serve as a supplement to the e-mail list.

Unity 2017.2 Stereo

It appears that Unity has accidentally left out the “Stereo Non-Head Mounted” option in the Virtual Reality Supported settings in a Unity 2017.2 release. More info on how to work-around this here:

And it sounds like it will be re-added in a next release:

Let’s hope so!

Input Updates

Colleagues at the Idaho National Laboratory have added a tool management system to the plugin to allow for improved navigation and interaction with UI elements!
