Graphic Engines

We were using multiple commercial graphic engines (Unity, Unreal) to facilitate the development of Virtual Reality experiments for our different hardware setups.
 
 

We primarily used the Unity game engine from Unity Technologies for development and deployment of our experiments. With the help of the commercial middleware solution MiddleVR from I'm in VR, we were able to run Unity based experiments in all of our VR labs. We were able to transition existing Unity experiments with relatively small effort from one VR setup to another. One example would be a HMD based experiment which was later run in the PanoLab cluster-rendering setup. Unreal Engine 4 (UE4) was used as an alternative when high-visual fidelity was needed such as helicopter and driving simulation visuals. We have extended UE4 with VRPN tracking capabilities, which allowed us to run UE4 in a mobile VR setup in our large tracking hall. A custom UDP plugin allowed it to be used with our motion simulators like the CableRobot Simulator or CyberPod.

The discontinued Virtools software from Dassault Systèmes is no longer used for new experiments.
