Detailed Description

Face structure.

Version
2.0

For the m_sSurfaceDomain member, the face domain for the usage of the surface; must be included in surface's domain. If not defined (that is, invalid domain with Min > Max), the face domain is the surface domain.

The number of loops: m_uiLoopSize can be null, in this case the surface is bounded by its domain or by the face domain: m_sSurfaceDomain if m_bHasTrimDomain is true.

When parsing an A3DTopoFaceData structure, use a tolerance that is the greater of these values:

Field Documentation

A3DUns16 A3DTopoFaceData::m_usStructSize

Reserved; must be initialized with A3D_INITIALIZE_DATA.

A3DSurfBase* A3DTopoFaceData::m_pSurface

Basis surface. Cannot be null.

A3DBool A3DTopoFaceData::m_bHasTrimDomain

Has the surface a trim domain?

A3DDomainData A3DTopoFaceData::m_sSurfaceDomain

Trimming domain for surface.

A3DUns32 A3DTopoFaceData::m_uiLoopSize

Number of A3DTopoLoop in next array.

A3DTopoLoop** A3DTopoFaceData::m_ppLoops

Array of A3DTopoLoop. None can be null.

A3DUns32 A3DTopoFaceData::m_uiOuterLoopIndex

Outer loop index. A3D_LOOP_UNKNOW_OUTER_INDEX if unknown.

A3DDouble A3DTopoFaceData::m_dTolerance

Face tolerance.
