| dc.description.abstract | In this paper we present a volume rendering technique for the ad-hoc visualization of interactive particle systems. We focus on methods for an efficient spatial caching (topology caching) of particles when applying a raycasting approach. Thus, we get a fast reconstruction of the scalar field which is defined by the particles' entities. The node-cache allows for efficient caching and pre-fetching of a subset of the octree nodes. The influence-cache provides fast access to all particles which contribute to a specific node including level-of-detail particles. Finally, the introduced slab-cache allows for efficient volume rendering and gradient computation. Our algorithms are completely built and managed on the GPU and interactive frame rates for up to several 105 particles are achieved. | en_US |
