A novel memory access mechanism for arbitrary-view-projection volume rendering
- State Univ. of New York, Stony Brook, NY (United States). Computer Science Dept.
Direct rendering of volume data is both conceptually simpler and more capable of producing visually superior results than other rendering methods. Special hardware architecture for direct volume rendering enables interactive exploration of volume data from arbitrary projection angles, which would otherwise take significantly longer due to its enormous computation a memory requirements. This paper proposes a new architecture called FAVOR, which features a novel memory access scheme that eliminates the most critical bottleneck in hardware rendering machines, and provides conflict-free parallel accesses to volume data. A preliminary performance analysis shows that the extra overhead incurred by this scheme is rather marginal, within 20% of the target performance for a 16 frames/sec volume rendering rate at the 512x512x512 resolution.
