In the liquid simulation, the density or velocity information stored as a volume data can be visualized by volume rendering. However, a time-varying volume data tends to be spatially and temporally very large. In this paper, we proposed a spatio-temporal compression method by introducing motion compression prediction in addition to the conventional VDB method. We evaluated a compression radio and compression error by using PSNR and showed that our method can decrease compression error by adding differences created from motion compensation prediction. However, we found that our method caused a worse compression ratio than VDB when extracting all differences. We then improved our method not to extract vertices which changes slightly, and showed better compression ratio than VDB by such the improvement. |
