| Abstract(in English) | We present an efficient SIMD optimized implementation of the parallel voxel-based forward projection algorithm. The algorithm rasterizes RLE encoded volume data in a front to back manner by utilizing a specialized view transform. In addition to the original method, our implementation achieves a significant speedup by utilizing a multi-segment culling mechanism in combination with a binary visibility map. We show that it is possible to uncompress and visualize large volume data directly from GPU memory without streaming data from slower CPU memory.. |
