int osg::RenderBuffer::compare ( const RenderBuffer rb) const
inline
static void osg::RenderBuffer::deleteRenderBuffer ( unsigned int  contextID,
GLuint  rb 
)
static

Mark internal RenderBuffer for deletion.

Deletion requests are queued until they can be executed in the proper GL context.

void osg::RenderBuffer::dirtyAll ( ) const
inlineprotected
static void osg::RenderBuffer::discardDeletedRenderBuffers ( unsigned int  contextID)
static

discard all the cached RenderBuffers which need to be deleted in the OpenGL context related to contextID.

Note, unlike flush no OpenGL calls are made, instead the handles are all removed. this call is useful for when an OpenGL context has been destroyed.

static void osg::RenderBuffer::flushDeletedRenderBuffers ( unsigned int  contextID,
double  currentTime,
double &  availableTime 
)
static

flush all the cached RenderBuffers which need to be deleted in the OpenGL context related to contextID.

If State is non-zero, this function releases any associated OpenGL objects for the specified graphics context.

Otherwise, releases OpenGL objexts for all graphics contexts.

Reimplemented from osg::Object.

virtual void osg::RenderBuffer::resizeGLObjectBuffers ( unsigned int  maxSize)
