_autogenerateMipmaps()

void Ogre::D3D11TextureGpu::_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::D3D11TextureGpu::_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::D3D11TextureGpuWindow.

_notifyTextureSlotChanged()

void Ogre::D3D11TextureGpu::_notifyTextureSlotChanged ( const TexturePool *  newPool, uint16  slice  )

overridevirtual

Reimplemented from Ogre::TextureGpu.

Reimplemented in Ogre::D3D11TextureGpuWindow.

_setToDisplayDummyTexture()

void Ogre::D3D11TextureGpu::_setToDisplayDummyTexture ( )

overridevirtual

Implements Ogre::TextureGpu.

Reimplemented in Ogre::D3D11TextureGpuWindow.

copyTo()

void Ogre::D3D11TextureGpu::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'
