Constructor & Destructor Documentation

◆ D3D9HardwareOcclusionQuery()

Ogre::D3D9HardwareOcclusionQuery::D3D9HardwareOcclusionQuery ( )

Default object constructor.

◆ ~D3D9HardwareOcclusionQuery()

Ogre::D3D9HardwareOcclusionQuery::~D3D9HardwareOcclusionQuery ( )

Object destructor.

Member Function Documentation

◆ beginOcclusionQuery()

void Ogre::D3D9HardwareOcclusionQuery::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.

◆ endOcclusionQuery()

void Ogre::D3D9HardwareOcclusionQuery::endOcclusionQuery ( )
virtual

Ends the hardware occlusion test.

Implements Ogre::HardwareOcclusionQuery.

◆ getLastQuerysPixelcount() [1/2]

unsigned int Ogre::D3D9HardwareOcclusionQuery::getLastQuerysPixelcount ( )

◆ getLastQuerysPixelcount() [2/2]

unsigned int Ogre::HardwareOcclusionQuery::getLastQuerysPixelcount ( ) const
inlineinherited

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.

◆ isStillOutstanding()

bool Ogre::D3D9HardwareOcclusionQuery::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.

◆ lockDeviceAccess()

static void Ogre::D3D9Resource::lockDeviceAccess ( )
staticinherited

◆ notifyOnDeviceCreate()

virtual void Ogre::D3D9HardwareOcclusionQuery::notifyOnDeviceCreate ( IDirect3DDevice9 *  d3d9Device)
virtual

Reimplemented from Ogre::D3D9Resource.

◆ notifyOnDeviceDestroy()

virtual void Ogre::D3D9HardwareOcclusionQuery::notifyOnDeviceDestroy ( IDirect3DDevice9 *  d3d9Device)
virtual

Reimplemented from Ogre::D3D9Resource.

◆ notifyOnDeviceLost()

virtual void Ogre::D3D9HardwareOcclusionQuery::notifyOnDeviceLost ( IDirect3DDevice9 *  d3d9Device)
virtual

Reimplemented from Ogre::D3D9Resource.

◆ notifyOnDeviceReset()

virtual void Ogre::D3D9HardwareOcclusionQuery::notifyOnDeviceReset ( IDirect3DDevice9 *  d3d9Device)
virtual

Reimplemented from Ogre::D3D9Resource.

template<class Alloc >
void* Ogre::AllocatedObject< Alloc >::operator new ( size_t  sz,
const char *  file,
int  line,
const char *  func 
)
inlineinherited

operator new, with debug line info

◆ operator new() [3/3]

template<class Alloc >
void* Ogre::AllocatedObject< Alloc >::operator new ( size_t  sz,
void *  ptr 
)
inlineinherited

)
inlineinherited

array operator new, with debug line info

◆ pullOcclusionQuery()

bool Ogre::D3D9HardwareOcclusionQuery::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
NumOfFragmentswill get the resulting number of fragments.
Returns
True if success or false if not.

Implements Ogre::HardwareOcclusionQuery.
