Split a mesh by vertex groups?

@songuke

Hi,
I want to split a mesh into individual triangles. The way to do is select a face in edit mode and press Y (or the Split button in the Mesh tools tab). But is there anyway to do it in Python script? Since I want to execute this split for every triangles in the mesh. Note that when selecting all faces and press Split, it doesn’t work.

Thanks in advance.

If your mesh is already all triangles:

1. Select all edges
2. Ctrl+E -> Mark Sharp.
3. Add and Apply Edge Split modifier to the object
4. Done
