The Triangulate node converts all faces in a mesh (quads and n-gons) to triangular faces. It functions the same as the Triangulate tool in Edit Mode.
- Quad Method
Split the quads in nice triangles, slower method.
Split the quads on their 1st and 3rd vertices.
- Fixed Alternate
Split the quads on their 2nd and 4th vertices.
- Shortest Diagonal
Split the quads based on the diagonal distance between their vertices.
- N-gon Method
Arrange the new triangles nicely, slower method.
Splits n-gons using an ear-clipping algorithm (gives similar results to the tessellation used for the viewport rendering).
Standard geometry output.
