In this study we use the CAVE2 which is a approximately 24 feet in diameter and 8 feet tall, and consists of 72 near-seamless passive stereo off-axis-optimized 3D LCD panels, a 36-node high-performance computer cluster, and a 20-speaker surround audio system. CAVE2 provides users with a 320-degree panoramic field of vision. The headtracking is done by the vaicon system which is a 10-camera optical tracking system which uses infrared techonlogy to capture motion. 3D glasses which have infrared pointers for tracking and enable the user to have a stereo 3D experience inside the cave.
We use Google sketchup to create the model for the stimulus. Unity3D and the getReal3D plugin for Unity3D by Mechdyne which is a plugin which allows Unity3D to be run on a cluster of displays to render the stimulus and the virtual environment surrounding it.
