This class // provides control over both the method of construction of the initial // mesh and also the criteria for subsequent refinement. // The initial tesselation is specified by the polygon output type, and the // isoparm type. The secondary tesselation (or subdivision) is specified by // the tesselation format. // // ***************************************************************************** #if defined __cplusplus // ***************************************************************************** // INCLUDED HEADER FILES #include #include // ***************************************************************************** // FORWARD DECLARATIONS class MMatrix; // ***************************************************************************** // CLASS DECLARATION (MTesselationParams) /// Tesselation parameters /** */ #ifdef _WIN32 #pragma warning(disable: 4522) #endif // _WIN32 class OPENMAYA_EXPORT MTesselationParams { public: /// Tesselation format enum TessFormat { /// kTriangleCountFormat, /// kStandardFitFormat, /// kGeneralFormat }; /// Output Types enum PolyType { /// kTriangles, /// kQuads }; /// IsoparmType enum IsoparmType { /// kSurface3DDistance, /// kSurface3DEquiSpaced, /// kSurfaceEquiSpaced, /// kSpanEquiSpaced }; /// Subdivision flags enum SubdivisionType { /// kUseFractionalTolerance, /// kUseChordHeightRatio, /// kUseMinEdgeLength, /// kUseMaxEdgeLength, /// kUseMaxNumberPolys, /// kUseMaxSubdivisionLevel, /// kUseMinScreenSize, /// kUseMaxUVRectangleSize, /// kUseTriangleEdgeSwapping, /// kUseRelativeTolerance, /// kUseEdgeSmooth, /// kLastFlag }; /// MTesselationParams ( TessFormat format = kStandardFitFormat, PolyType = kTriangles ); MTesselationParams ( const MTesselationParams & ); /// ~MTesselationParams (); // General parameters /// void setFormatType( TessFormat type ); /// void setOutputType( PolyType type ); // Parameters for triangulization format /// void setTriangleCount( int ); // Parameters for standard fit format /// void setStdChordHeightRatio( double ); /// void setStdFractionalTolerance( double ); /// void setStdMinEdgeLength( double ); // Parameters for general tesselation format /// void setSubdivisionFlag( SubdivisionType type, bool use ); /// void setFitTolerance( double ); /// void setChordHeightRatio( double ); /// void setMinEdgeLength( double ); /// void setMaxEdgeLength( double ); /// void setMaxNumberPolys( int ); /// void setMaxSubdivisionLevel( double ); /// void setMinScreenSize( double, double ); /// void setWorldspaceToScreenTransform( MMatrix & ); /// void setMaxUVRectangleSize( double, double ); /// void setRelativeFitTolerance( double ); /// void setEdgeSmoothFactor( double ); /// void set3DDelta( double ); // U,V isoparm based parameters /// void setUIsoparmType( IsoparmType type ); /// void setVIsoparmType( IsoparmType type ); /// void setUNumber( int count ); /// void setVNumber( int count ); /// void setBoundingBoxDiagonal( double distance ); /// void setUDistanceFraction( double value ); /// void setVDistanceFraction( double value ); /// MTesselationParams &operator= ( const MTesselationParams &rhs); // The default tesselation parameters /// static MTesselationParams fsDefaultTesselationParams; protected: // No protected members private: friend class MFnNurbsSurface; const char* className() const; void * data; }; #ifdef _WIN32 #pragma warning(default: 4522) #endif // _WIN32 // ***************************************************************************** #endif /* __cplusplus */ #endif /* _MTesselationParams */
