Triangulate Node

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.

Inputs

Mesh

Standard geometry input.

Selection

A standard Boolean selection input to determine which faces will be triangulated.

Minimum Vertices

Minimum number of vertices a face must have to be triangulated. For example, setting this value to 5, will prevent triangulation of Quads and only triangulate N-gons.

Properties

Quad Method

• Beauty:

  Split the quads in nice triangles, slower method.

  Fixed:

  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 along their shortest diagonal.

  Longest Diagonal:

  Split the quads along their longest diagonal. This is the preferred mode for cloth simulations.

N-gon Method

• Beauty:

  Arrange the new triangles nicely, slower method.

  Clip:

  Split n-gons using an ear-clipping algorithm (the same method of tessellation used for viewport display).

Outputs

Mesh

Standard geometry output.
