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 );

Let's you get the last pixel count with out doing the hardware occlusion test.
- Returns
- The last fragment count from the last test. Remarks This function won't give you new values, just the old value.

Pulls the hardware occlusion query.
- Note
- Waits until the query result is available; use isStillOutstanding if just want to test if the result is available.
- Return values
-
| NumOfFragments | will get the resulting number of fragments. |
- Returns
- True if success or false if not.
