>Also I have a long time this idea in my mind: implement tetrahedrons as efficiently as possible and build generic polyhedron as a clump of these tetrahedrons

Interesting. In a sense it is what PFacets are doing, except that the primitives are spheres, cylinders, and triangles.
They define a deformable truss by default but if they are clumped it becomes a rigid object. Some efficiency comparisons could be worth it.
