wears a headgear and is head-tracked so that the correct perspective view is gener-
ated for his/her eyes. The user can navigate through the 3D scene using a handheld
controller like a joystick. The joystick position and orientation in space is tracked
too so the user can potentially reach into the data and click on a point of inter-
est. The first versions were run by expensive multi-CPU machines specialized for
graphics processing and later versions are run by Linux clusters using commodity
graphics and processing hardware.
Since its invention in 1991, many CAVE installations have appeared at uni-
versities and research organizations across the globe and proven to be invaluable
for scientific visualization and data exploration. As seen in Figure 14.10, complex
protein and biological structures can be understood better because of the high pixel
Figure 14.11 (a) How the barrier linescreen technology is used for generating pixel sets which are
only visible to one eye at a time. Two such sets enable stereo vision. (b) A user interacting with the
stereo display without using glasses.
