Detailed Description

       The SoMultipleCopy class redraws it's children multiple times at different
       transformations.

       The SoMultipleCopy group node duplicates it's children nodes / subgraphs without using
       additional memory resources.

       It can do general transformations (translations, rotation and scaling) for it's children.
       Apart from transformations, the appearance of it's children will be identical.

       FILE FORMAT/DEFAULTS:

       MultipleCopy {
           matrix 1 0 0 0
           0 1 0 0
           0 0 1 0
           0 0 0 1
       }

Member Function Documentation

   SoType SoMultipleCopy::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 * SoMultipleCopy::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 SoGroup.

   SbBool SoMultipleCopy::affectsState (void) const [virtual]
       Returns TRUE if the node could have any effect on the state during traversal.

       If it returns FALSE, no data in the traversal-state will change from the pre-traversal
       state to the post-traversal state. The SoSeparator node will for instance return FALSE, as
       it pushes and pops the state before and after traversal of its children. All SoShape nodes
       will also return FALSE, as just pushing out geometry data to the rendering engine won't
       affect the actual rendering state.

       The default method returns TRUE, on a 'better safe than sorry' philosophy.

       Reimplemented from SoNode.

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

       Reimplemented from SoGroup.

   void SoMultipleCopy::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 SoGroup.

   void SoMultipleCopy::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 SoGroup.

   void SoMultipleCopy::pick (SoPickAction *action) [virtual]
       Action method for SoPickAction.

       Does common processing for SoPickAction action instances.

       Reimplemented from SoGroup.

   void SoMultipleCopy::getBoundingBox (SoGetBoundingBoxAction *action) [virtual]
       Action method for the SoGetBoundingBoxAction.

       Calculates bounding box and center coordinates for node and modifies the values of the
       action to encompass the bounding box for this node and to shift the center point for the
       scene more towards the one for this node.

       Nodes influencing how geometry nodes calculates their bounding box also overrides this
       method to change the relevant state variables.

       Reimplemented from SoGroup.

   void SoMultipleCopy::handleEvent (SoHandleEventAction *action) [virtual]
       Action method for SoHandleEventAction.

       Inspects the event data from action, and processes it if it is something which this node
       should react to.

       Nodes influencing relevant state variables for how event handling is done also overrides
       this method.

       Reimplemented from SoGroup.

   void SoMultipleCopy::getMatrix (SoGetMatrixAction *action) [virtual]
       Action method for SoGetMatrixAction.

       Updates action by accumulating with the transformation matrix of this node (if any).

       Reimplemented from SoGroup.

   void SoMultipleCopy::search (SoSearchAction *action) [virtual]
       Action method for SoSearchAction.

       Compares the search criteria from the action to see if this node is a match. Searching is
       done by matching up all criteria set up in the SoSearchAction -- if any of the requested
       criteria is a miss, the search is not deemed successful for the node.

           SoSearchAction

       Reimplemented from SoGroup.

   void SoMultipleCopy::getPrimitiveCount (SoGetPrimitiveCountAction *action) [virtual]
       Action method for the SoGetPrimitiveCountAction.

       Calculates the number of triangle, line segment and point primitives for the node and adds
       these to the counters of the action.

       Nodes influencing how geometry nodes calculates their primitive count also overrides this
       method to change the relevant state variables.

       Reimplemented from SoGroup.

   void SoMultipleCopy::audioRender (SoAudioRenderAction *action) [virtual]
       Action method for SoAudioRenderAction.

       Does common processing for SoAudioRenderAction action instances.

       Reimplemented from SoGroup.

Member Data Documentation

   SoMFMatrix SoMultipleCopy::matrix
       A set of geometry transformation matrices.

       The number of duplicated redraws of the child geometry will be the same as the number of
       matrices specified in this field. Ie, each duplication will be transformed according to a
       transformation matrix.

       The default value of the field is to contain just a single identity matrix.
