Detailed Description

Opaque struct that holds effective FSAA (MSAA, CSAA, etc.) mode.

Note that you can request a SampleDescription, but you may get the closest quality if that particular setting is not supported by the GPU.

Additionally, device lost events can cause FSAA settings to be degraded on the fly Listen for TextureGpuListener::FsaaSettingAlteredByApi events to be notified of this

_set()

void Ogre::SampleDescription::_set	(	uint8	colourSamples,
		uint8	coverageSamples,
		MsaaPatterns::MsaaPatterns	pattern
	)

For internal use.

getColourSamples()

uint8 Ogre::SampleDescription::getColourSamples ( void  ) const

inline

getCoverageSamples()

uint8 Ogre::SampleDescription::getCoverageSamples ( void  ) const

inline

getFsaaDesc() [1/2]

void Ogre::SampleDescription::getFsaaDesc

(

LwString &

outFsaaSetting

)

const

Appends the FSAA description to the string.

getFsaaDesc() [2/2]

void Ogre::SampleDescription::getFsaaDesc

(

String &

outFsaaSetting

)

const

Appends the FSAA description to the string.

getMaxSamples()

uint8 Ogre::SampleDescription::getMaxSamples ( void  ) const

inline

References Ogre::max().

getMsaaPattern()

MsaaPatterns::MsaaPatterns Ogre::SampleDescription::getMsaaPattern ( void  ) const

inline

References Ogre::MsaaPatterns::Undefined.

isCsaa()

bool Ogre::SampleDescription::isCsaa

(

void

)

const

Returns true if this is CSAA, whether it's quality or not.

Remarks

There is some overlap between CSAA and EQAA modes, hence this function may return true even if setEqaa was called

isCsaaQuality()

bool Ogre::SampleDescription::isCsaaQuality

(

void

)

const

Returns true if this is CSAA in quality mode.

Remarks

There is some overlap between CSAA and EQAA modes, hence this function may return true even if setEqaa was called

isMsaa()

bool Ogre::SampleDescription::isMsaa

(

void

)

const

isMultisample()

bool Ogre::SampleDescription::isMultisample ( void  ) const

inline

operator!=()

bool Ogre::SampleDescription::operator!= ( const SampleDescription &  rhs ) const

inline

operator<()

bool Ogre::SampleDescription::operator< ( const SampleDescription &  other ) const

inline

operator==()

bool Ogre::SampleDescription::operator== ( const SampleDescription &  rhs ) const

inline

parseString()

void Ogre::SampleDescription::parseString

(

const String &

fsaaSetting

)

setCsaa()

void Ogre::SampleDescription::setCsaa	(	uint8	samples,
		bool	bQuality
	)

Set CSAA by NVIDIA's marketing names e.g.

8x CSAA call setCsaa( 8u, false ) 8x CSAA (Quality) then call setCsaa( 8u, true ) 16x CSAA call setCsaa( 16u, false ) 16x CSAA (Quality) then call setCsaa( 16u, true )

Parameters

samples	Marketing value. Can be 8 or 16
bQuality	True to use the 'quality' variation, false otherwise

setEqaa()

void Ogre::SampleDescription::setEqaa	(	uint8	colourSamples,
		uint8	coverageSamples
	)

Set EQAA by its marketing number (which coincides with its technical spec) e.g.

2f4x EQAA call setEqaa( 2u, 4u ) 4f8x EQAA call setEqaa( 4u, 8u ) 8f16x EQAA call setEqaa( 8u, 16u )

Parameters

mColourSamples
coverageSample

setMsaa()

void Ogre::SampleDescription::setMsaa	(	uint8	msaa,
		MsaaPatterns::MsaaPatterns	pattern = MsaaPatterns::Undefined
	)
