virtual FbxNodeAttribute::EType GetAttributeType ( ) const [virtual]

Search for all occurrences

Returns the type of node attribute.

Reimplemented from FbxGeometry.

int GetTrimRegionCount ( ) const

Search for all occurrences

Returns the number of regions on this trimmed NURBS surface.

Note: There is always at least one region.

Returns:: The number of regions

void BeginTrimRegion ( )

Search for all occurrences

Calls this function before adding boundaries to a new trim region.

The number of regions is incremented on this call.

void EndTrimRegion ( )

Search for all occurrences

Calls this function after the last boundary for a given region is added.

If no boundaries are added between the calls to BeginTrimRegion and EndTrimRegion, the last region is removed.

bool AddBoundary ( FbxBoundary * pBoundary )

Search for all occurrences

Appends a trimming boundary to the set of trimming boundaries.

The first boundary specified for a given trim region should be the outer boundary. All other boundaries are inner boundaries. This must be called after a call to BeginTrimRegion(). Boundaries cannot be shared among regions. Duplicate the boundary if necessary.

Parameters:

pBoundary The boundary to add.

Returns:: True if the boundary is added successfully. If the boundary is not added successfully, returns false.

FbxBoundary* GetBoundary	(	int	pIndex,
		int	pRegionIndex = `0`
	)

Search for all occurrences

Returns the boundary at a given index for the specified region.

Parameters:

pIndex	The index of the boundary to retrieve, no bound checking is done.
pRegionIndex	The index of the region which is bordered by the boundary.

Returns:: The trimming boundary at index pIndex, if pIndex is in the range [0, GetBoundaryCount() ), otherwise the result is undefined.

FbxBoundary const* GetBoundary	(	int	pIndex,
		int	pRegionIndex = `0`
	)		const

Search for all occurrences

Returns the boundary at a given index for the specified region.

Parameters:

pIndex	The index of the boundary to retrieve, no bound checking is done.
pRegionIndex	The index of the region which is bordered by the boundary.

Returns:: The trimming boundary at index pIndex, if pIndex is in the range [0, GetBoundaryCount() ), otherwise the result is undefined.

int GetBoundaryCount ( int pRegionIndex = 0 ) const

Search for all occurrences

Returns the number of boundaries for a given region.

Parameters:

pRegionIndex The index of the region.

Returns:: The number of trim boundaries for the given region.

void SetNurbsSurface ( FbxNurbsSurface const * pNurbs )

Search for all occurrences

Sets the NURBS surface that is trimmed by the trimming boundaries.

Parameters:

pNurbs The NURBS surface to be trimmed.

FbxNurbsSurface* GetNurbsSurface ( )

Search for all occurrences

Returns the NURBS surface that is trimmed by the trim boundaries.

Returns:: A pointer to the (untrimmed) NURBS surface.

FbxNurbsSurface const* GetNurbsSurface ( ) const

Search for all occurrences

Returns the NURBS surface that is trimmed by the trim boundaries.

Returns:: A pointer to the (untrimmed) NURBS surface.

void SetFlipNormals ( bool pFlip ) [inline]

Search for all occurrences

Sets the flag which indicates whether the surface normals are flipped.

You can flip the normals of the surface to reverse the surface.

Parameters:

pFlip If true, the surface is reversed. If it is false, the surface is not reversed.

Definition at line 188 of file fbxtrimnurbssurface.h.

{ mFlipNormals = pFlip; }

bool GetFlipNormals ( ) const [inline]

Search for all occurrences

Checks if the normals are flipped.

Returns:: True if normals are flipped, returns false if they are not flipped.

Definition at line 193 of file fbxtrimnurbssurface.h.

{ return  mFlipNormals; }

virtual int GetControlPointsCount ( ) const [virtual]

Search for all occurrences

Returns the number of control points.

Returns:: The number of control points allocated in the geometry.

Reimplemented from FbxGeometryBase.

virtual void SetControlPointAt	(	FbxVector4 &	pCtrlPoint,
		FbxVector4 &	pNormal,
		int	pIndex
	)		`[virtual]`

Search for all occurrences

Sets the control point and the normal values for a specified index.

Parameters:

pCtrlPoint	The value of the control point.
pNormal	The value of the normal.
pIndex	The specified index.

virtual FbxVector4* GetControlPoints ( FbxStatus * pStatus = NULL ) const [virtual]

Search for all occurrences

Returns the NURBS surface's control points.

Parameters:

pStatus The FbxStatus object to hold error codes.

virtual FbxObject& Copy ( const FbxObject & pObject ) [virtual]

Search for all occurrences

Copy an object content into this object.

Parameters:

pObject The source object to copy data from.

Returns:: Returns the destination object being modified by the source.

Remarks:: This function replace the assignment operator (operator=). It will copy all property values and the name. Connections are NOT copied.

Reimplemented from FbxGeometry.
