Function Documentation

FindTriangulation()

DllExport void FindTriangulation	(	Mesh &	m,
		int	deg,
		int *	vv,
		int *	tri
	)

Remarks

This global function is available in release 3.0 and later only. Finds a triangulation of an n-sided polygon using vertices in the specified mesh. As long as the vertices are coplanar, this algorithm will find a proper triangulation, even for nonconvex polygons.

Parameters:

Mesh &m The mesh containing the vertices used in the polygon. int deg The size of the polygon. int *vv The vertex indices of the polygon, in order around the perimeter. For instance, if deg is 5 and w points to an array containing (3, 6, 8, 0, 7), the polygon is presumed to have the outline described by m.verts[3], m.verts[6], m.verts[8], m.verts[0], and m.verts[7]. int *tri This is where the output is placed. Note that this should point to an array of size at least (deg-2)*3, to hold all the triangles. The values placed in this array are indices into the w array – that is, given a 5-sided polygon, one triangle in this list might be (0,2,3), indicating you should use the 0th, 2nd, and 3rd elements of w to form the triangle. Put another way, to make a face from the n'th triangle given by this array, you would set: f.v[0] = w[tri[n*3+0]]; f.v[1] = w[tri[n*3+1]]; f.v[2] = w[tri[n*3+2]];
