This class is the iterator for polygonal surfaces (meshes). The iterator functions in two modes depending on whether a component is specified. When a component is not given or is NULL the iteration will be over all polygons for the surface. When a component is given this iterator will iterate over the polygons (faces) specified in the component. When iterating over components a DAG path to the surface must also be supplied. */ class OPENMAYA_EXPORT MItMeshPolygon { public: MItMeshPolygon( const MObject & polyObject, MStatus * ReturnStatus = NULL ); MItMeshPolygon( const MDagPath &polyObject, MObject & component = MObject::kNullObj, MStatus * ReturnStatus = NULL ); virtual ~MItMeshPolygon(); bool isDone( MStatus * ReturnStatus = NULL ); MStatus next(); MStatus reset(); MStatus reset( const MObject & polyObject ); MStatus reset( const MDagPath &polyObject, MObject & component = MObject::kNullObj ); // Count methods. unsigned int count( MStatus * ReturnStatus = NULL ); unsigned int polygonVertexCount( MStatus * ReturnStatus = NULL ); MPoint center( MSpace::Space space = MSpace::kObject, MStatus * ReturnStatus = NULL ) ; // Obsolete MObject polygon( MStatus * ReturnStatus = NULL ); MObject currentItem( MStatus * ReturnStatus = NULL ); unsigned int index( MStatus * ReturnStatus = NULL ); MStatus setIndex(int index, int &prevIndex); // Vertex methods. unsigned int vertexIndex( int index, MStatus * ReturnStatus = NULL ); MStatus getVertices( MIntArray & vertices ); MPoint point( int index, MSpace::Space space = MSpace::kObject, MStatus * ReturnStatus = NULL ); void getPoints( MPointArray & pointArray, MSpace::Space space = MSpace::kObject, MStatus * ReturnStatus = NULL ); MStatus setPoint( const MPoint & point, unsigned int index, MSpace::Space space = MSpace::kObject ); MStatus setPoints( MPointArray & pointArray, MSpace::Space space = MSpace::kObject ); // Normal methods. unsigned int normalIndex( int vertex, MStatus * ReturnStatus = NULL) const; MStatus getNormal( MVector & normal, MSpace::Space space = MSpace::kObject) const; MStatus getNormal( unsigned int Vertexindex, MVector & normal, MSpace::Space space = MSpace::kObject) const; MStatus getNormals( MVectorArray & vectorArray, MSpace::Space space = MSpace::kObject) const; unsigned int tangentIndex( int vertex, MStatus * ReturnStatus = NULL ) const; // Uv methods. bool hasUVs( MStatus * ReturnStatus = NULL ) const; bool hasUVs( const MString & uvSet, MStatus * ReturnStatus = NULL ) const; MStatus setUV( int vertexId, float2 & uvPoint, const MString * uvSet = NULL); MStatus getUV( int vertexId, float2 & uvPoint, const MString * uvSet = NULL) const; MStatus setUVs( MFloatArray& uArray, MFloatArray& vArray, const MString * uvSet = NULL); MStatus getUVs( MFloatArray& uArray, MFloatArray& vArray, const MString * uvSet = NULL) const; MStatus getPointAtUV( MPoint &pt, float2 & uvPoint, MSpace::Space space = MSpace::kObject, const MString * uvSet = NULL, float tolerance=0.0 ); MStatus getUVAtPoint( MPoint &pt, float2 & uvPoint, MSpace::Space space = MSpace::kObject, const MString * uvSet = NULL); MStatus getUVIndex( int vertex, int & index, const MString *uvSet = NULL ); MStatus getUVIndex( int vertex, int & index, float & u, float & v, const MString *uvSet = NULL); MStatus getUVSetNames( MStringArray &setNames) const; // Color methods. bool hasColor(MStatus * ReturnStatus = NULL ) const; bool hasColor(int localVertexIndex, MStatus * ReturnStatus = NULL ); MStatus getColor(MColor &color, const MString *colorSetName = NULL); MStatus getColor(MColor &color, int vertexIndex); MStatus getColors(MColorArray &colors, const MString *colorSetName = NULL); MStatus numColors( int &count, const MString *colorSetName = NULL ); MStatus getColorIndex(int vertexIndex, int & colorIndex, const MString *colorSetName = NULL); MStatus getColorIndices(MIntArray & colorIndex, const MString *colorSetName = NULL); // Triangulation methods. bool hasValidTriangulation(MStatus * ReturnStatus = NULL) const; MStatus numTriangles(int &count) const; MStatus getTriangle( int localTriIndex, MPointArray & points, MIntArray & vertexList, MSpace::Space space = MSpace::kObject) const; MStatus getTriangles(MPointArray & points, MIntArray & vertexList, MSpace::Space space = MSpace::kObject) const; MStatus updateSurface(); MStatus geomChanged(); // Info convinience methods.
