The 3D TV with the ceiling-mounted NaturalPoint OptiTrack optical tracking system. The three cameras are aligned such that their fields of view graze the 3D TV's screen, and overlap in the main work area in front of the TV.
The ELSA Revelator-style 3D shutter glasses, with a "tracking antler" consisting of four retro-reflective balls held together by 1/8" wood dowels and 1/2" wood cubes. The wood cubes are glues to the glasses using 1/2" thick foamy double-sided poster tape.
The Wii controller tracked input device, with a "tracking antler" consisting of three retro-reflective balls.
Using the Wii controller to select from the Nanotech Construction Kit's main menu. This photo was taken using a head-tracked camera, by mounting a spare "tracking antler" onto the camera itself.
Using the Wii controller to interact with a virtual quartz crystal by dragging individual silicate building blocks.
A short low-quality movie of a camera pan through the environment's work area using a head-tracked camera.
Movie showing 3D Visualizer and medical data set on a low-cost VR environment.
Analyzing a 3D CAT scan using the Visualizer application. The two clusters of cameras mounted to either side of the 3D TV are not an intrinsic part of the low-cost VR environment, but are used to capture immersive 3D video of the person or persons using the environment to support remote collaboration.
Same, using Vrui's Curve Editor tool to annotate the 3D CAT scan.
Multiple users interacting in the environment. Only one of the users (the one on the right, wearing the head-tracked stereo glasses) sees the 3D model with proper projection.
Our low-cost VR system at the SCEC workshop in Palm Springs (before we turned it on, duh).
