Member Function Documentation

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 [inline, protected]
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.
