Perspective volume rendering on Parallel Algebraic Logic (PAL) computer
Wanqing Li, Hongchi Shi · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1998
We propose a perspective volume graphics rendering algorithm on SIMD mesh-connected computers and implement the algorithm on the Parallel Algebraic Logic computer. The algorithm is a parallel ray casting algorithm. It decomposes the 3D perspective projection into two transformations that can be implemented in the SIMD fashion to solve the data redistribution problem caused by non-regular data access patterns in the perspective projection.
