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.

SYNOPSIS

       #include <Inventor/nodes/SoTransformSeparator.h>

       Inherits SoGroup.

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 (int nChildren) 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

   void SoTransformSeparator::initClass (void) [static] Sets up initialization
       for data common to all instances of this class, like submitting
       necessary information to the Coin type system.
       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.
