Detailed Description

       The SoVRMLCoordinateInterpolator class is used to interpolate 3D coordinates.

       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:

       CoordinateInterpolator {
         eventIn      SFFloat set_fraction        # (-inf, inf)
         exposedField MFFloat key           []    # (-inf, inf)
         exposedField MFVec3f keyValue      []    # (-inf, inf)
         eventOut     MFVec3f value_changed
       }

       This node linearly interpolates among a list of MFVec3f values. The number of coordinates
       in the keyValue field shall be an integer multiple of the number of keyframes in the key
       field. That integer multiple defines how many coordinates will be contained in the
       value_changed events. 4.6.8, Interpolator nodes
       (http://www.web3d.org/x3d/specifications/vrml/ISO-
       IEC-14772-VRML97/part1/concepts.html#4.6.8), contains a more detailed discussion of
       interpolators.

Member Function Documentation

   SoType SoVRMLCoordinateInterpolator::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.

   const SoFieldData * SoVRMLCoordinateInterpolator::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 SoVRMLInterpolator.

   const SoEngineOutputData * SoVRMLCoordinateInterpolator::getOutputData (void) const [virtual]
       This API member is considered internal to the library, as it is not likely to be of
       interest to the application programmer.
