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-><a class="el" href="classOgre_1_1D3D9HardwareOcclusionQuery.html#Ogre_1_1D3D9HardwareOcclusionQuerya3">endOcclusionQuery()</a>;.
<p>
Results must be pulled using: UINT m_uintNumberOfPixelsVisable; pullOcclusionQuery( &m_dwNumberOfPixelsVisable ); You may not get the result directlly after the first pass or frame. Objects not visable must be tested every frame, visable objects may be tested less freqvent.

Remarks This function allows you to set how often the hardware occlusion really are sent to the driver if you set it to 0 every hw occlusion test is acctually made.
<p>
If you set it to 1 only the half of your queries are sent for all visable objects. 2 will result in 25% of all queries to acctualy be sent. New and none visable objects will be tested all the time. This functionality is here because this class can keep track on visable and none visable objects for you. Once you you set the SkipRate for any hardware occlusion instance it effects all others.
