Interactive Deformation and Visualization of Level Set Surfaces using Graphics Hardware

August 29th, 2003

This IEEE Visualization 2003 paper by Lefohn et al. describes the computation and visualization of deforming level-set surfaces on a GPU. The paper describes a new technique for efficiently processing the dynamic, sparse volumes encountered in level-set computations. The technique stores a packed representation of the sparse volume on the GPU and performs both the level-set computation and real-time volume rendering on this packed format. The new level-set solver is shown to be 10-15 times faster than an optimized CPU implementation. The paper demonstrates the new algorithm with a volume segmentation application.
