IsQuad()

bool ON_MeshTopologyFace::IsQuad

(

)

const

A topological mesh face is a valid quad if m_topei[0], m_topei[1], m_topei[2], and m_topei[3] are distinct edges.

Returns

True if face is a quad.

IsTriangle()

bool ON_MeshTopologyFace::IsTriangle

(

)

const

A topological mesh face is a valid triangle if m_topei[0], m_topei[1], m_topei[2] are distinct edges and m_topei[3]=m_topei[2].

Returns

True if face is a triangle.

IsValid()

bool ON_MeshTopologyFace::IsValid

(

)

const

A topological mesh face is valid if m_topei[0], m_topei[1], and m_topei[2] are mutually distinct, and m_topei[3] is either equal to m_topei[2] or mutually distinct from the first three indices.

Returns

True if face is valid.
