Abstract

The present work deals with the interactive simulation and in situ visualisation of planetary ring systems. Such systems are represented by a set of particles which are loaded as position data stored in a certain format. To allow real time simulation an existing N-Body-Simulation from the CUDA toolkit is used, which alters the position data right in the VRAM. Therefrom the particles can be rendered efficiently by combining dynamic point sprites and a texture approximating the local densities. The dynamic point sprites get recreated each use depending on the light and camera positions and using proceduraly generated 3D models, the approximation of the density texture gets realised by splatting.
