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.
