Our current research focuses on haptically assisted fragment reassembly. To this end, we examined vector field methods for handling collisions of complex, non-convex, rigid objects as well as for haptic rendering. A GPU-based approach is used to pre-compute 3D Voronoi cells. Furthermore, inside/outside information, normals and distances to object surfaces are determined on a sample grid.
