Constructor & Destructor Documentation

Ogre::D3D11HardwareOcclusionQuery::D3D11HardwareOcclusionQuery ( D3D11Device & device )

Default object constructor.

Ogre::D3D11HardwareOcclusionQuery::~D3D11HardwareOcclusionQuery ( )

Object destructor.

Member Function Documentation

void Ogre::D3D11HardwareOcclusionQuery::beginOcclusionQuery ( ) [virtual]

Starts the hardware occlusion query.

Remarks:: Simple usage: Create one or more OcclusionQuery object one per outstanding query or one per tested object OcclusionQuery* mOcclusionQuery; createOcclusionQuery( &mOcclusionQuery ); In the rendering loop: Draw all occluders mOcclusionQuery->startOcclusionQuery(); Draw the polygons to be tested mOcclusionQuery->endOcclusionQuery();

Results must be pulled using: UINT mNumberOfPixelsVisable; pullOcclusionQuery( &mNumberOfPixelsVisable );

Implements Ogre::HardwareOcclusionQuery.

void Ogre::D3D11HardwareOcclusionQuery::endOcclusionQuery ( ) [virtual]

Ends the hardware occlusion test.

Implements Ogre::HardwareOcclusionQuery.

unsigned int Ogre::D3D11HardwareOcclusionQuery::getLastQuerysPixelcount ( )

Definition at line 78 of file OgreD3D11HardwareOcclusionQuery.h.

References Ogre::HardwareOcclusionQuery::mPixelCount.

unsigned int Ogre::HardwareOcclusionQuery::getLastQuerysPixelcount ( ) const [inherited]

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.

Definition at line 109 of file OgreHardwareOcclusionQuery.h.

bool Ogre::D3D11HardwareOcclusionQuery::isStillOutstanding ( void ) [virtual]

Lets you know when query is done, or still be processed by the Hardware.

Returns:: true if query isn't finished.

Implements Ogre::HardwareOcclusionQuery.

bool Ogre::D3D11HardwareOcclusionQuery::pullOcclusionQuery ( unsigned int * NumOfFragments ) [virtual]

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.
