Stereo in Volume Rendering• Provide depth cues not possible in 2D images– Binocular disparity specified by interocular distanceto produce Left-Right images• Volume rendering amorphous structures,– Spatial relationships, structure and scale and howthey evolve with time in 4D simulations• Critical for immersive environments – eg CAVE,Virtual endoscopy apps
3D Vision stereo for Quadro• Supports existing OpenGL Quadbuffer apps• Works on Win XP, Vista– 185.xx drivers– Linux under dev• Supported boards– Onboard stereo connector(FX 3700 and above)– USB on lower-end boardshttp://www.nvidia.com/object/quadro_pro_graphics_boards.html3-pin mini dinStereo cableDual-link DVIL,R,L,R,…IR emitter120Hz PanelActive shutter glasses
