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();. Results must be pulled using: UINT m_uintNumberOfPixelsVisable; pullOcclusionQuery( &m_dwNumberOfPixelsVisable ); Implements Ogre::HardwareOcclusionQuery. |
