void ViewPort3D::drawPatch	(	double	p1[3],
		double	p2[3],
		double	p3[3],
		int	level
	)

This is recursively subdivides a triangular area (vertices p1,p2,p3) into smaller triangles, and then draws the triangles. All triangle vertices are normalized to a distance of 1.0 from the origin (p1,p2,p3 are assumed to be already normalized). Note this is not super-fast because it draws triangles rather than triangle strips.
