Constructor & Destructor Documentation

◆ PTQMask_3()

PTQMask_3::PTQMask_3 ( PolygonMesh pmesh)

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.
