Choose a method to adapt Convex Hulls

The project is hard to explain but mathematicians and computers researchers can easily understand the task. The final goal will be to locate light probes (or tetrahedrons) in a 3D scene to generate indirect illumination. The problem with our current implementation is that the the full convex hull may produce not enough light probes because of merging multiples convex hulls agorithm made by our ingeneers. I must notice that there are 2 algorithms for location generation : one is by light probes, the other is by using light propagation volumes for very close meshes. We previously tried to solve this problem by using 5D or 4D convex hull and test with matlab and we also tried to solve this problem by using multiple types of convex hulls types but, now, we encounter hesitation. The source code will be provided.
