Detailed Description

Numeric data function set.

MFnNumericData allows the creation and manipulation of numeric data objects for use in the dependency graph. Normally, data objects are not required for the transmission of numeric data. The graph supports numeric types directly (see the methods of MDataHandle).

Numeric data objects are useful if you have an attribute that accepts generic data. A generic attribute can accept multiple types of data, so you cannot hardwire it to accept a specific type of numeric data. So, generic attributes can only accept numeric data in the form of actual data objects.

This function set only supports pairs and triples of numeric data.

Examples:

apiMeshShape.cpp, blindDataShader.cpp, cgfxAttrDef.cpp, componentScaleManip.cpp, curvedArrowsNode.cpp, D3DViewportRenderer.cpp, footPrintManip.cpp, genericAttributeNode.cpp, geometrySurfaceConstraint.cpp, GLSLShaderNode.cpp, hwAnisotropicShader_NV20.cpp, hwDecalBumpShader_NV20.cpp, hwReflectBumpShader_NV20.cpp, hwToonShader_NV20.cpp, hwUnlitShader.cpp, pnTrianglesNode.cpp, polyModifierCmd.cpp, renderAccessNode.cpp, rotateManip.cpp, surfaceBumpManip.cpp, and swissArmyManip.cpp.
