| Ogre::HardwareOcclusionQuery::HardwareOcclusionQuery | ( | ) |
Object public member functions.
Default object constructor
| virtual Ogre::HardwareOcclusionQuery::~HardwareOcclusionQuery | ( | ) | [virtual] |
Object destructor.
| virtual void Ogre::HardwareOcclusionQuery::beginOcclusionQuery | ( | ) | [pure virtual] |
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 );
| virtual void Ogre::HardwareOcclusionQuery::endOcclusionQuery | ( | ) | [pure virtual] |
Ends the hardware occlusion test.
| virtual bool Ogre::HardwareOcclusionQuery::pullOcclusionQuery | ( | unsigned int * | NumOfFragments | ) | [pure virtual] |
Pulls the hardware occlusion query.
| NumOfFragments | will get the resulting number of fragments. |
| unsigned int Ogre::HardwareOcclusionQuery::getLastQuerysPixelcount | ( | ) | const |
Let's you get the last pixel count with out doing the hardware occlusion test.
