Detailed Description

       The SoVRMLColor class is used to specify multiple colors for a single shape.

       The detailed class documentation is taken verbatim from the VRML97 standard (ISO/IEC
       14772-1:1997). It is copyright The Web3D Consortium, and is used by permission of the
       Consortium:

       Color {
         exposedField MFColor color  []         # [0,1]
       }

       This node defines a set of RGB colours to be used in the fields of another node.

       Color nodes are only used to specify multiple colours for a single geometric shape, such
       as colours for the faces or vertices of an IndexedFaceSet. A Material node is used to
       specify the overall material parameters of lit geometry. If both a Material node and a
       Color node are specified for a geometric shape, the colours shall replace the diffuse
       component of the material. RGB or RGBA textures take precedence over colours; specifying
       both an RGB or RGBA texture and a Color node for geometric shape will result in the Color
       node being ignored. Details on lighting equations can be found in 4.14, Lighting model
       (http://www.web3d.org/x3d/specifications/vrml/ISO-
       IEC-14772-VRML97/part1/concepts.html#4.14).

Member Function Documentation

   SoType SoVRMLColor::getTypeId (void) const [virtual]
       Returns the type identification of an object derived from a class inheriting SoBase. This
       is used for run-time type checking and 'downward' casting. Usage example:

       void foo(SoNode * node)
       {
         if (node->getTypeId() == SoFile::getClassTypeId()) {
           SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
         }
       }

       For application programmers wanting to extend the library with new nodes, engines,
       nodekits, draggers or others: this method needs to be overridden in all subclasses. This
       is typically done as part of setting up the full type system for extension classes, which
       is usually accomplished by using the pre-defined macros available through for instance
       Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes),
       Inventor/engines/SoSubEngine.h (for engine classes) and so on.

       For more information on writing Coin extensions, see the class documentation of the
       toplevel superclasses for the various class groups.

       Implements SoBase.

   const SoFieldData * SoVRMLColor::getFieldData (void) const [protected],  [virtual]
       Returns a pointer to the class-wide field data storage object for this instance. If no
       fields are present, returns NULL.

       Reimplemented from SoFieldContainer.

   void SoVRMLColor::doAction (SoAction *action) [virtual]
       This function performs the typical operation of a node for any action.

       Reimplemented from SoNode.

   void SoVRMLColor::GLRender (SoGLRenderAction *action) [virtual]
       Action method for the SoGLRenderAction.

       This is called during rendering traversals. Nodes influencing the rendering state in any
       way or who wants to throw geometry primitives at OpenGL overrides this method.

       Reimplemented from SoNode.

   void SoVRMLColor::callback (SoCallbackAction *action) [virtual]
       Action method for SoCallbackAction.

       Simply updates the state according to how the node behaves for the render action, so the
       application programmer can use the SoCallbackAction for extracting information about the
       scene graph.

       Reimplemented from SoNode.
