Function Documentation

triangulate_polygon()

uint32_t miniply::triangulate_polygon	(	uint32_t	n,
		const float	pos[],
		uint32_t	numVerts,
		const int	indices[],
		int	dst[]
	)

Given a polygon with n vertices, where n > 3, triangulate it and store the indices for the resulting triangles in dst. The pos parameter is the array of all vertex positions for the mesh; indices is the list of n indices for the polygon we're triangulating; and dst is where we write the new indices to.

The triangulation will always produce n - 2 triangles, so dst must have enough space for 3 * (n - 2) indices.

If n == 3, we simply copy the input indices to dst. If n < 3, nothing gets written to dst.

The return value is the number of triangles.

Here is the caller graph for this function:
