Constructor.

The default vertex point property map is used.

Member Function Documentation

border_node()

void PTQMask_3::border_node	(	halfedge_descriptor	hd,
		Point_3 &	ept,
		Point_3 &	vpt
	)

computes the edge-point ept and the vertex-point vpt based on the neighborhood of the border edge of hd.

hd is not a border halfedge (its opposite is) and vpt corresponds to the target vertex of hd.
