CGAL::Linear_mask_3< PolygonMesh, VertexPointMap >.
The geometry mask of Catmull-Clark subdivision.
A stencil determines a source neighborhood whose points contribute to the position of a refined point. The geometry mask of a stencil specifies the computation on the nodes of the stencil. CatmullClark_mask_3
implements the geometry masks of Catmull-Clark subdivision on models of MutableFaceGraph
, such as Polyhedron_3
and Surface_mesh
.
PolygonMesh | must be a model of the concept MutableFaceGraph . |
VertexPointMap | must be a model of WritablePropertyMap with value type Point_3 |
