◆ IsSmoothOrDartOrCrease()

bool ON_SubDVertex::IsSmoothOrDartOrCrease ( ) const

Returns: True if m_vertex_tag is ON_SubDVertexTag::Smooth or ON_SubDVertexTag::Dart or ON_SubDVertexTag::Crease.

◆ IsStandard()

bool ON_SubDVertex::IsStandard ( ) const

Description: A "standard" vertex is one where the standard subdivsion matrix for that vertex can be used to calculate the subdivision point. This function is designed to be useful for testing and debugging code when a certain situation is expected to exist. It is not used for evaluation because it is too slow.

Returns: True if the subdivison point of the vertex can be calculated using the standard subdivion matrix for the vertex type and face count.

Remarks: If the vertex is tagged and has multiple sectors, like an interior crease or corner vertex, then this function will return false. In this situation, it is possible that the vertex, as the center of a sector, is standard.

◆ IsTwoSectorCrease()

bool ON_SubDVertex::IsTwoSectorCrease ( ) const

There are 2 configurations a valid crease vertex can have.

1) A crease vertex with one sector has EdgeCount() = 1+FaceCount(), two crease edges that are attached to a single face, and the other edges are smooth and are attached to two faces.

2) A crease vertex with two sectors has EdgeCount() = FaceCount(), two crease edges, and all edges are attached to two faces.

In a complete SubD (not a subset), a 1 sector crease vertex is always on the boundary of the SubD. In all cases a 2 sector crease vertex is an interior vertex.

Parameters

bUseCreaseSharpness	When bCountCreasesAsSharp is true, crease edges are counted.

Parameters

bCountCreasesAsSharp	When bCountCreasesAsSharp is true, creases are counted and ON_SubDEdgeSharpness::CreaseValue is used as a crease edge sharpness.
