CGAL::Linear_mask_3< PolygonMesh, VertexPointMap >.
The geometry mask of Sqrt(3) 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. Sqrt3_mask_3
implements the geometry masks of \( \sqrt{3}\) subdivision on a triangulated model of MutableFaceGraph
, such as Polyhedron_3
and Surface_mesh
.
PolygonMesh | must be a model of the concept MutableFaceGraph . Additionally all faces must be triangles. |
VertexPointMap | must be a model of WritablePropertyMap with value type Point_3 |
