Function Documentation

IsTriangleInRange()

bool IsTriangleInRange ( const unsigned int * aFaceIdx, unsigned int aTriangleIdx, unsigned int aVertexCount )

inline

Test whether the three face indices of a triangle all reference valid vertices.

Malformed mesh data can carry indices past the end of the vertex array; consuming them would read out of bounds and produce corrupt geometry, so callers skip any triangle this rejects.

Parameters

aFaceIdx	Face index array (SMESH::m_FaceIdx).
aTriangleIdx	Offset of the triangle's first index into aFaceIdx.
aVertexCount	Number of vertices available (SMESH::m_VertexSize).
