Constructor & Destructor Documentation

Triangle()

rcsc::DelaunayTriangulation::Triangle::Triangle	(	const int	id,
		EdgePtr	e0,
		EdgePtr	e1,
		EdgePtr	e2 )

create triangle with index and edges

Parameters

id	Id number of this triangle
e0	raw pointer to the first edge instance
e1	raw pointer to the second edge instance
e2	raw pointer to the third edge instance

pointers to the vertices are automatically set from edges.
