Remarks
Compute triangulation of simple 2D polygon using ear-clipping
Parameters
| Name | Description |
|---|---|
| VertexPositions | ordered vertices of 2D polygon |
| OutTriangles | computed triangulation. Each triangle is a tuple of indices into VertexPositions. |
| bOrientAsHoleFill | if true, output triangles are wound opposite of the input polygon; this is typically desired when the polygon comes from the boundary of a hole |
