Detailed Description

A CFace contains the information related to a given face in a CFaceList.

CFace is most of the time built from CFaceList::GetFace method. It represents a single face of this list at the specified index. CFace is the base class for more specific classes C3DFace, CUVWFace...
It contains an array of indexes that refers to CPointList.

Note: CFaces indexes can be modified or resized but do not forget that they are part of the whole CFaceList, which is in a single memory block.
Resizing faces (especially if indexes are added) can lead to numerous memory reallocations and loss of performance.
The CFaceList class contains a number of methods for pre-allocating memory, so that a call to SetSize does not lead to inappropriate memory reallocations.

bool	IsFlagSet (FACE_PROPERTIES) const

bool	IsOneFlagSet (int flag) const

void	SetFlag (FACE_PROPERTIES, bool set)

void	SetFlags (unsigned int flags, bool set)

void	Inherit (const CFace &srcface)
	Inherit srcface chunks (and so flags and others properties), but don't copy the srcface indexes.

bool	Copy (const CFace &srcface)

bool	Copy (unsigned int srcindex)

int *	SetSize (int size, FACE_PROPERTIES invalidFlag=FACE_IS_INVALID)
	Set the number of indexes for the face. If size < 3, then invalidFlag flag is set, if size >= 3 the flag is removed.. For channel flags, FACE_IS_UNUSED should be used to keep the same number of faces between 3d faces and channel faces, if the matching 3d face is not set to invalid on a clean operation.

void	SetQuadrangle (int pointindex1, int pointindex2, int pointindex3, int pointindex4)

void	Flip ()

bool	IsOnePointFlagSet (const CGeomInfo *info, unsigned int pointPropertiesFlags, bool set)
	check if one point has one of the pointPropertiesFlags set or unset (call IsPointFlagSet internally)

FLAGRESULT	IsPointFlagSet (const CGeomInfo *info, unsigned int pointPropertiesFlags, bool set)
	check how many points have one of the pointPropertiesFlags set or unset (call IsPointFlagSet internally)

void	SetPointFlag (const CGeomInfo *info, unsigned int pointPropertiesFlags, bool set)

int	IsFacePoint (int pointindex)
	Check if point index belong to face. Return the index position of this pointindex or POINT_NOT_BELONG_TO_FACE.

int	GetPrevIndex (int offset) const

int	GetNextIndex (int offset) const
