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]
Destructor.

Member Function Documentation

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

See also
    close()

    call()

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

See also
    open()

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

See also
    open()

  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 nothing.

Reimplemented from SoCache.
