NAME

       SoTransformSeparator -

       The SoTransformSeparator class is a group node preserving the current transformations.

       This node works like the SoSeparator group node, except that it only stores and restores
       the current model matrix transformation. Other appearance settings, like materials,
       textures, cameras, lights, etc, will affect the remaining parts of the scenegraph after
       traversal, just like as for the SoGroup node.

Detailed Description

       The SoTransformSeparator class is a group node preserving the current transformations.

       This node works like the SoSeparator group node, except that it only stores and restores
       the current model matrix transformation. Other appearance settings, like materials,
       textures, cameras, lights, etc, will affect the remaining parts of the scenegraph after
       traversal, just like as for the SoGroup node.

       FILE FORMAT/DEFAULTS:

Constructor & Destructor Documentation

   SoTransformSeparator::SoTransformSeparator (void)
       Default constructor.

   SoTransformSeparator::SoTransformSeparator (intnChildren)
       Constructor.

       The argument should be the approximate number of children which is expected to be inserted
       below this node. The number need not be exact, as it is only used as a hint for better
       memory resource allocation.

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

Member Function Documentation

   SoType SoTransformSeparator::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 SoGroup.

   const SoFieldData * SoTransformSeparator::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.

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

       Reimplemented from SoGroup.

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

       Does common processing for SoPickAction action instances.

       Reimplemented from SoGroup.

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

       Does common processing for SoAudioRenderAction action instances.

       Reimplemented from SoGroup.
