Triangulate Modifier

The Triangulate modifier converts all faces in a mesh (whether it be quads or N-gons) to triangular faces. This modifier does the exact same function as the triangulate function Ctrl-T in Edit Mode.

Quad Method:
Split the quads in nice triangles, slower method.
Split the quads on the 1st and 3rd vertices.
Fixed Alternate
Split the quads on the 2nd and 4th vertices.
Shortest Diagonal
Split the quads based on the distance between the vertices.
Ngon Method:
Arrange the new triangles nicely, slower method.
Split the ngons using a scanfill algorithm.
