Member Function Documentation

EnsureImageLayout()

void ezPipelineBarrierVulkan::EnsureImageLayout	(	const ezGALTextureVulkan *	pTexture,
		vk::ImageLayout	dstLayout,
		vk::PipelineStageFlags	dstStages,
		vk::AccessFlags	dstAccess,
		bool	bDiscardSource = false
	)

Transition the given texture's image into the given layout to be used in the given stage.

Parameters

pTexture	The texture whose image's layout is to be changed.
dstLayout	The layout that the image is to be changed into.
dstStages	In what stages the image needs to be in the new layout.
dstAccess	What access we will be doing on the image in dstStages.
bDiscardSource	Discard the previous layout, replaces current layout with unknown.

SetInitialImageState()

void ezPipelineBarrierVulkan::SetInitialImageState	(	const ezGALTextureVulkan *	pTexture,
		vk::ImageLayout	dstLayout,
		vk::PipelineStageFlags	dstStages = vk::PipelineStageFlagBits::eTopOfPipe,
		vk::AccessFlags	dstAccess = {}
	)

Force, sets the layout of the texture's image. Most images are not created in their preferred layout on creation.

Parameters

pTexture	The texture whose image the initial state should be set on.
dstLayout	The layout that the image currently is in.
dstStages	In what stage the image was changed into the current layout.
dstAccess	The access operation that changed the image into the current layout during dstStages.
