Triangulate Modifier

Mode: Object mode

Panel: Properties Window -> Context Button Modifiers CZ Modifier ContextButton.png


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 Ctrl+T triangulate in Edit Mode

Mesh before Triangulate Modifier

Quad 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.
