Convex/concave Quads to Tris script?

Is there available anything like this?

I guess not

If you decide to code one, here’s a quick “recipe” about how it should work:

  1. Iterate through faces.
  2. If face is a quad (has four verts), then check angles of the adjacent edges of it.
  3. If any angle is bigger than 180 degrees, then add the face to list of quads to be triangulated.
  4. Do 1.-3. till each face has been iterated.
  5. Triangulate quads to be triangulated. (I noticed Blender’s ctrl-t did this okay. There may be another way too.)
