		uint32	textureFlags,
		TextureTypes::TextureTypes	initialType,
		TextureGpuManager *	textureManager

override

Member Function Documentation

◆ _autogenerateMipmaps()

void Ogre::GL3PlusTextureGpu::_autogenerateMipmaps ( CopyEncTransitionMode::CopyEncTransitionMode transitionMode = CopyEncTransitionMode::Auto )

overridevirtual

Tells the API to let the HW autogenerate mipmaps.

Assumes allowsAutoMipmaps() == true and isRenderToTexture() == true

Parameters

transitionMode See CopyEncTransitionMode::CopyEncTransitionMode

Implements Ogre::TextureGpu.

◆ _isDataReadyImpl()

bool Ogre::GL3PlusTextureGpu::_isDataReadyImpl ( ) const

overridevirtual

For internal use.

Do not call directly.

This function is the same isDataReady except it ignores pending residency changes, which is important when TextureGpuManager needs to know this information but the TextureGpu is transitioning (thus mPendingResidencyChanges is in an inconsistent state)

Implements Ogre::TextureGpu.

Reimplemented in Ogre::GL3PlusTextureGpuWindow.

◆ _notifyTextureSlotChanged()

void Ogre::GL3PlusTextureGpu::_notifyTextureSlotChanged	(	const TexturePool *	newPool,
		uint16	slice
	)

overridevirtual

Reimplemented from Ogre::TextureGpu.

Reimplemented in Ogre::GL3PlusTextureGpuHeadlessWindow, and Ogre::GL3PlusTextureGpuWindow.

◆ _setToDisplayDummyTexture()

void Ogre::GL3PlusTextureGpu::_setToDisplayDummyTexture ( )

overridevirtual

Implements Ogre::TextureGpu.

Reimplemented in Ogre::GL3PlusTextureGpuWindow.

◆ copyTo()

void Ogre::GL3PlusTextureGpu::copyTo	(	TextureGpu *	dst,
		const TextureBox &	dstBox,
		uint8	dstMipLevel,
		const TextureBox &	srcBox,
		uint8	srcMipLevel,
		bool	keepResolvedTexSynced = `true`,
		CopyEncTransitionMode::CopyEncTransitionMode	srcTransitionMode = `CopyEncTransitionMode::Auto`,
		CopyEncTransitionMode::CopyEncTransitionMode	dstTransitionMode = `CopyEncTransitionMode::Auto`
	)

overridevirtual

Parameters

dst
dstBox
dstMipLevel
srcBox
srcMipLevel
keepResolvedTexSynced	When true, if dst is an MSAA texture and is implicitly resolved (i.e. dst->hasMsaaExplicitResolves() == false); the resolved texture is also kept up to date.

Typically the reason to set this to false is if you plane on rendering more stuff to dst texture and then resolve.

Parameters

srcTransitionMode	Transition mode for 'this'
dstTransitionMode	Transition mode for 'dst'

Reimplemented from Ogre::TextureGpu.

◆ getCustomAttribute()

void Ogre::GL3PlusTextureGpu::getCustomAttribute	(	IdString	name,
		void *	pData
	)

overridevirtual

Reimplemented from Ogre::TextureGpu.

Reimplemented in Ogre::GL3PlusTextureGpuHeadlessWindow, and Ogre::GL3PlusTextureGpuWindow.

◆ getDisplayTextureName()

GLuint Ogre::GL3PlusTextureGpu::getDisplayTextureName ( ) const

inline

Returns the GLuid of the texture that is being displayed.

While the texture is being loaded (i.e. data is not ready), we will display a dummy white texture. Once notifyDataIsReady, getDisplayTextureName should be the same as getFinalTextureName. In other words, getDisplayTextureName may change its returned value based on the texture's status

◆ getFinalTextureName()

GLuint Ogre::GL3PlusTextureGpu::getFinalTextureName ( ) const

inline

Always returns the internal handle that belongs to this texture.

Note that for TextureFlags::AutomaticBatching textures, this will be the handle of a 2D Array texture pool.

If the texture has MSAA enabled, this returns the handle to the resolve texture, not the MSAA one.

If TextureFlags::MsaaExplicitResolve is set, it returns the handle to the MSAA texture, since there is no resolve texture.

◆ getGlTextureTarget()

GLenum Ogre::GL3PlusTextureGpu::getGlTextureTarget ( ) const

inline

Returns GL_TEXTURE_2D / GL_TEXTURE_2D_ARRAY / etc.

◆ getMsaaFramebufferName()

GLuint Ogre::GL3PlusTextureGpu::getMsaaFramebufferName ( ) const

inline

If MSAA > 1u and TextureFlags::MsaaExplicitResolve is not set, this returns the handle to the temporary MSAA renderbuffer used for rendering, which will later be resolved into the resolve texture.

Otherwise it returns null.

◆ getSubsampleLocations()

void Ogre::GL3PlusTextureGpu::getSubsampleLocations ( vector< Vector2 >::type locations )

overridevirtual

Get the MSAA subsample locations.

mSampleDescription.pattern must not be MsaaPatterns::Undefined.

Parameters

locations Outputs an array with the locations for each subsample. Values are in range [-1; 1]

Implements Ogre::TextureGpu.

Reimplemented in Ogre::GL3PlusTextureGpuWindow.

◆ notifyDataIsReady()

void Ogre::GL3PlusTextureGpu::notifyDataIsReady ( )

overridevirtual

Notifies it is safe to use the real data. Everything has been uploaded.

Implements Ogre::TextureGpu.

Reimplemented in Ogre::GL3PlusTextureGpuWindow.

◆ setTextureType()

void Ogre::GL3PlusTextureGpu::setTextureType ( TextureTypes::TextureTypes textureType )

overridevirtual

Reimplemented from Ogre::TextureGpu.

Reimplemented in Ogre::GL3PlusTextureGpuHeadlessWindow, and Ogre::GL3PlusTextureGpuWindow.
