COVRA: A compression-domain output-sensitive volume rendering architecture based on a sparse representation of voxel blocks

Enrico Gobbetti, José Antonio Iglesias Guitián, Fabio Marton
2012 Computer graphics forum (Print)  
We present a novel multiresolution compression-domain GPU volume rendering architecture designed for interactive local and networked exploration of rectilinear scalar volumes on commodity platforms.  ...  The result is a scalable high quality coding scheme, which allows very large volumes to be compressed off-line and then decompressed on-demand during real-time GPU-accelerated rendering.  ...  In our approach -dubbed Compressiondomain Output-sensitive Volume Rendering Architecture (COVRA) -the volume is decomposed into a multiresolution hierarchy of bricks.  ...

To this end we develop a volume compression algorithm tailored to high reduction rates in visualization applications; we explore compressed-domain processing possibilities including multiresolution convolution  ...  To this end we develop a volume compression algorithm tailored to high reduction rates in visualization applications; we explore compressed-domain processing possibilities including multiresolution convolution  ...  Thus, tensor decomposition domain filtering is not an overhead introduced on top of compression domain volume rendering but rather a cost reduction compared to direct volume filtering.  ...
