The SoGLRenderCache class is used to cache OpenGL calls.
SoGLRenderCache::SoGLRenderCache | ( | SoState * | state | ) |
Constructor with state being the current state.
SoGLRenderCache::~SoGLRenderCache | ( | ) | [virtual] |
Destructor.
void SoGLRenderCache::open | ( | SoState * | state | ) |
void SoGLRenderCache::close | ( | void | ) |
Closes the cache. Should be called after all GL calls.
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.
