Volume Rendering for 3D GEEKs
VolumePro Product page at TeraRecon (gen3 is still made, but not marketed externally)
VolumePro Timeline - Started as a research project at MERL, then spun out to RTViz and then aquired by TeraRecon. We are working on the 3rd generation ASIC.

Front to Back blending is possible with a buffer to accumulate alpha. The normal back to front blending: ColorAccum = (1 - OpacityNew)*ColorAccum + ColorNew OpacityAccum = (1 - OpacityNew)*OpacityAccum + OpacityNew Front to Back ColorAccum = (1 - OpacityAccum)*ColorNew + ColorAccum OpacityAccum = (1 - OpacityAccum)*OpacityNew + OpacityAccum from: A coherent projection approach for direct volume rendering.

Whiz kids wanted. What are there so few Pythagorean solids? If you understand the question, let me know.
