ADAPTIVE USAGE OF AVAILABLE STORAGE FOR ACCELERATED VOLUME RENDERING

摘要

In order to decrease a memory footprint for volume rendering, distance field information is adaptively compressed and merged with an existing data structure having unused memory to form a merged dataset. During rendering, the merged dataset is sampled, and a sampled value is used to identify a look-up table for a corresponding voxel or is decompressed and used to skip empty space.
