This sketch paper presents an overview of "Fast Scene Voxelization and Applications" published at the ACM SIGGRAPH Symposium on Interactive 3D Graphics and Games. It introduces slicemaps that correspond to a GPU friendly voxel representation of a scene. This voxelization is done at run-time in the order of milliseconds, even for complex and dynamic scenes containing more than 1M polygons. Creation and storage is performed on the graphics card avoiding unnecessary data transfer. Regular but also deformed grids are possible, in particular to better fit the scene geometry. Several applications are demonstrated: shadow calculation, refraction simulation and shadow volume culling/clamping.
