The VolumePro real-time ray-casting system

摘要

This paper describes VolumePro; the world's first single-chip real-tiem volume rendering system for ocnsumer PCs.VolumePro implements ray-casting with parallel slice-by-slice processing.Our discussion of the architecture focuses mainly on the rendering pipeline and the memory organization.VolumePro has hardware for gradient estimation,classification,and per-sample Phong illumination.The system does not perform any pre-processing and makes parameter adjustments and changes to the volume dat aimmediately visible.
