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