An Improved HVQ Algorithm for Compression and Rendering of Space Environment Volume Data with Multi-variables

Funds: Key Research Program of the Chinese Academy of Sciences
  • 摘要: Space environment simulation can produce several correlated variables at the same time. For space environment volume data with multi-correlated variables, based on HVQ-1d method we propose a further improved HVQ method by compositing variable-specific levels to reduce the redundant information among these variables. We further take advantage of progressive rendering based on GPU for real-time interactive visualization. The results of our experiments prove that the method proposed in this paper can pays the least cost of quality at compression and provides satisficed fidelity while ensuring interactive rendering speed in space environment domain. The proposed method can also be applied in other domains.
