CONT

We implemented an original approach for exact polygon-to-polygon visibility query. State-of-the art methods explicitely compute a representation, in [a] 5D space, of the set of rays blocked. In contrast, we search for a non-blocked ray. It can be proven that if such a ray exists, then a particular unblocked ray exists that is quadritangent to the scene (it passes through 4 edges of the polygonal model, including the two tested surfaces).
