◆ blit()

void Ogre::D3D11HardwarePixelBuffer::blit	(	const HardwarePixelBufferSharedPtr &	src,
		const Box &	srcBox,
		const Box &	dstBox
	)

virtual

Copies a box from another PixelBuffer to a region of the this PixelBuffer.

Parameters

src	Source pixel buffer
srcBox	Box describing the source region in src
dstBox	Box describing the destination region in this buffer

Remarks: The source and destination regions dimensions don't have to match, in which case scaling is done. This scaling is generally done using a bilinear filter in hardware, but it is faster to pass the source image in the right dimensions.

Note: Only call this function when both buffers are unlocked.

Reimplemented from Ogre::HardwarePixelBuffer.

◆ blitFromMemory()

void Ogre::D3D11HardwarePixelBuffer::blitFromMemory	(	const PixelBox &	src,
		const Box &	dstBox
	)

virtual

Copies a region from normal memory to a region of this pixelbuffer.

The source image can be in any pixel format supported by OGRE, and in any size.

Parameters

src	PixelBox containing the source pixels and format in memory
dstBox	Box describing the destination region in this buffer

Remarks: The source and destination regions dimensions don't have to match, in which case scaling is done. This scaling is generally done using a bilinear filter in hardware, but it is faster to pass the source image in the right dimensions.

Note: Only call this function when the buffer is unlocked.

Implements Ogre::HardwarePixelBuffer.

◆ blitToMemory()

void Ogre::D3D11HardwarePixelBuffer::blitToMemory	(	const Box &	srcBox,
		const PixelBox &	dst
	)

virtual

Copies a region of this pixelbuffer to normal memory.

Parameters

srcBox	Box describing the source region of this buffer
dst	PixelBox describing the destination pixels and format in memory

Remarks: The source and destination regions don't have to match, in which case scaling is done.

Note: Only call this function when the buffer is unlocked.

Implements Ogre::HardwarePixelBuffer.

◆ _genMipmaps()

void Ogre::D3D11HardwarePixelBuffer::_genMipmaps ( )

Internal function to update mipmaps on update of level 0.

◆ getParentTexture()

D3D11Texture* Ogre::D3D11HardwarePixelBuffer::getParentTexture ( ) const

◆ getFace()

UINT Ogre::D3D11HardwarePixelBuffer::getFace ( ) const

◆ getSubresourceIndex()

UINT Ogre::D3D11HardwarePixelBuffer::getSubresourceIndex ( size_t box_front ) const

◆ getSubresourceBox()
