Hello, I would like to know how to know if 2 triangles intersect together, in a 3D space. Does someone could help me? PS:Sorry for my english but I'm french :)

project them to 2D and go for a 2D test. Tomas Moeller has one optimized triangle intersection test. go for it !!

Hmm, i don't get how you can successfully test 3d triangles in 2d, hmm... except checking for interrupted edges.
I don't know about that method but i suggest checking if at least one of the 3 lines of every triangle intersects the other triangle and then use that information (intersection points ed) to do whatever you want to do (subdividing, etc.). This might be slow though.
