Constructor.

The default vertex point property map is used.

Member Function Documentation

border_node()

void Sqrt3Mask_3::border_node	(	halfedge_descriptor	hd,
		Point &	ept1,
		Point &	ept2,
		Point &	vpt
	)

computes the subdivided points ept1 and ept2 based on the neighborhood of the halfedge hd (whose opposite is on the border).

Along hd, ept1 comes before ept2. vpt is the updated point for the target vertex of hd.
