HardwareOcclusionQuery () | |
Default object constructor. | |
virtual | ~HardwareOcclusionQuery () |
Object destructor. | |
virtual void | beginOcclusionQuery ()=0 |
Starts the hardware occlusion query Simple usage: Create one or more OcclusionQuery object one per outstanding query or one per tested object OcclusionQuery* m_pOcclusionQuery; createOcclusionQuery( &m_pOcclusionQuery ); In the rendering loop: Draw all occluders m_pOcclusionQuery->startOcclusionQuery(); Draw the polygons to be tested m_pOcclusionQuery->endOcclusionQuery();. | |
virtual void | endOcclusionQuery ()=0 |
Ends the hardware occlusion test. | |
virtual bool | pullOcclusionQuery (unsigned int *NumOfFragments)=0 |
Pulls the hardware occlusion query. | |
unsigned int | getLastQuerysPixelcount () const |
Let's you get the last pixel count with out doing the hardware occlusion test. | |
virtual bool | isStillOutstanding (void)=0 |
Lets you know when query is done, or still be processed by the Hardware. | |
