Detailed Description

       The SoGLRenderCache class is used to cache OpenGL calls.

Constructor & Destructor Documentation

   SoGLRenderCache::SoGLRenderCache (SoState *state)
       Constructor with state being the current state.

   SoGLRenderCache::~SoGLRenderCache () [virtual]

Member Function Documentation

   void SoGLRenderCache::open (SoState *state)
       Opens the cache. All GL calls will be cached until close() is called.

       See Also:


   void SoGLRenderCache::close (void)
       Closes the cache. Should be called after all GL calls.

       See Also:

   void SoGLRenderCache::call (SoState *state)
       Executes the cached display list.

       See Also:

   int SoGLRenderCache::getCacheContext (void) const
       Returns the cache context of this cache. This is used to quickly determine if cache can be
       used for a state.

       This method is an extension versus the Open Inventor API.

   SbBool SoGLRenderCache::isValid (const SoState *state) const [virtual]
       Return TRUE if this cache is valid, FALSE otherwise.

       Reimplemented from SoCache.

   void SoGLRenderCache::addNestedCache (SoGLDisplayList *child) [virtual]
       Adds a display list which is called from this cache. This is to make sure the child
       display list isn't destroyed too early.

   void SoGLRenderCache::destroy (SoState *state) [protected],  [virtual]
       Can be overridden by subclasses to clean up before they are deleted. Default method does
