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:

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 nothing. Reimplemented from SoCache.
