Member Function Documentation

◆ _autogenerateMipmaps()

void Ogre::NULLTextureGpu::_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::NULLTextureGpu::_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.
