A project we collaborate with Gilles and Florence at INRIA. They have the nice nodal impact solver which implicitly handles contact and exact Coulomb friction very well. My work is merging close impacts and inserting nodes at the collision point so that their solver can be well integrated. A remeshing process was applied so that the triangulation of the mesh is well-conditioned, avoiding bad convergence of the solver. Also, I improved their solver to handle constraints on faces and edges (rather than just nodes). This improvement might boost the performance, which is under investigation.
A ray tracer renders with Phong model, which handles shadows, textures, refractions and reflections.
Reverse Simplification is an LOD algorithm that simplifies model from coarseness to refinement.
