Convert quadrangular faces or polygons to triangular ones.

Description

Convert quadrangular faces or polygons to triangular ones.

Usage

faces.quad.to.tris(quad_faces)

Arguments

quad_faces

nx4 integer matrix, the indices of the vertices making up the *n* quad faces.

Value

*2nx3* integer matrix, the indices of the vertices making up the *2n* tris faces.

Note

This function does no fancy remeshing, it simply splits each quad into two triangles.
