Detailed Description

       The SoClipPlaneElement class is used to manage the clip plane stack.

Constructor & Destructor Documentation

   SoClipPlaneElement::~SoClipPlaneElement () [protected, virtual] The
       destructor.

Member Function Documentation

   void SoClipPlaneElement::initClass (void) [static] Initialize relevant
       common data for all instances, like the type system.
       Reimplemented from SoAccumulatedElement.

       Reimplemented in SoGLClipPlaneElement.

   void SoClipPlaneElement::add (SoState *const  state, SoNode *const  node,
       const SbPlane & plane) [static] Adds plane as an active plane. Calls
       addToElt() to do the job.
   const SoClipPlaneElement * SoClipPlaneElement::getInstance (SoState *const
       state) [static] Returns the current (top-of-stack) element.
   int SoClipPlaneElement::getNum (void) const Returns the current number of
       active clipping planes.
   const SbPlane & SoClipPlaneElement::get (const int index, const SbBool
       inworldspace = 1) const Returns the ’th plane.
   void SoClipPlaneElement::addToElt (const SbPlane & plane, const SbMatrix &
       modelMatrix) [protected, virtual] This method adds the clipping plane,
       plane, to an instance. modelmatrix is the current model matrix.
       Reimplemented in SoGLClipPlaneElement.

Member Data Documentation

   SoClipPlaneElement::planes [protected] List of currently active planes.
   SoClipPlaneElement::startIndex [protected] Index of first clip plane in
       this element. Used to disable clip planes in
       SoGLClipPlaneElement::pop().
