       SoVRMLIndexedShape -

       The SoVRMLIndexedShape class is a superclass for geometry that use indexes.

SYNOPSIS

           Returns the type identification of an object derived from a class inheriting SoBase. This is used for
           run-time type checking and 'downward' casting.

Detailed Description

       The SoVRMLIndexedShape class is a superclass for geometry that use indexes.

Constructor & Destructor Documentation

   SoVRMLIndexedShape::SoVRMLIndexedShape (void) [protected]
       Constructor.

   SoVRMLIndexedShape::~SoVRMLIndexedShape () [protected],  [virtual]
       Destructor.

Member Function Documentation

   SoType SoVRMLIndexedShape::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.

       Reimplemented from SoVRMLVertexShape.

       Reimplemented in SoVRMLIndexedFaceSet.

   const SoFieldData * SoVRMLIndexedShape::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 SoVRMLVertexShape.

       Reimplemented in SoVRMLIndexedFaceSet.

   void SoVRMLIndexedShape::notify (SoNotList *l) [protected],  [virtual]
       Notifies all auditors for this instance when changes are made.

       Reimplemented from SoVRMLVertexShape.

   void SoVRMLIndexedShape::computeBBox (SoAction *action, SbBox3f &box, SbVec3f &center) [protected],
       [virtual]
       Implemented by SoShape subclasses to let the SoShape superclass know the exact size and weighted center
       point of the shape's bounding box.

       The bounding box and center point should be calculated and returned in the local coordinate system.

       The method implements action behavior for shape nodes for SoGetBoundingBoxAction. It is invoked from
       SoShape::getBoundingBox(). (Subclasses should not override SoNode::getBoundingBox().)

       The box parameter sent in is guaranteed to be an empty box, while center is undefined upon function
       entry.

       Implements SoShape.

   SbBool SoVRMLIndexedShape::getVertexData (SoState *state, const SoCoordinateElement *&coords, const SbVec3f
       *&normals, const int32_t *&cindices, const int32_t *&nindices, const int32_t *&tindices, const int32_t
       *&mindices, int &numcindices, const SbBoolneednormals, SbBool &normalcacheused) [protected]
       Convenience method that will fetch data needed for rendering or generating primitives. Takes care of
       normal cache.
