void	AfterBeginFrame ()
ezMutex &	AccessLock ()
vk::CommandBuffer	GetFinishedCommandBuffer ()
	Returns a finished command buffer of all background loading up to this point. The command buffer is already ended and marked to be reclaimed so the only thing done on it should be to submit it.
void	InitTexture (const ezGALTextureVulkan *pTexture, vk::ImageCreateInfo &createInfo, ezArrayPtr< ezGALSystemMemoryDescription > pInitialData)
	Initializes a texture and moves it into its default state.
void	TextureDestroyed (const ezGALTextureVulkan *pTexture)
	Needs to be called by the ezGALDeviceVulkan just before a texture is destroyed to clean up stale barriers.
void	InitBuffer (const ezGALBufferVulkan *pBuffer, ezConstByteArrayPtr pInitialData)
	Initializes a buffer with the given data.
void	UpdateTexture (const ezGALTextureVulkan *pTexture, const ezGALTextureSubresource &subresource, const ezBoundingBoxu32 &box, const ezGALSystemMemoryDescription &sourceData)
	Updates a texture region.

	Updates a buffer range.

	Used by ezUniformBufferPoolVulkan to write the entire uniform scratch pool to the GPU.

ExecutePendingCopies()

void ezInitContextVulkan::ExecutePendingCopies	(	ezArrayPtr< ezPendingBufferCopyVulkan >	buffers,
		ezArrayPtr< ezPendingTextureCopyVulkan >	textures
	)

Executes work generates by ezGALDeviceVulkan::UpdateBufferForNextFramePlatform and UpdateTextureForNextFramePlatform.

Parameters

buffers	The pending buffer copies.
textures	The pending texture copies.

InitBuffer()

void ezInitContextVulkan::InitBuffer	(	const ezGALBufferVulkan *	pBuffer,
		ezConstByteArrayPtr	pInitialData
	)

Initializes a buffer with the given data.

Parameters

pBuffer	The buffer to initialize.
pInitialData	The initial data that the buffer should be filled with.

InitTexture()

void ezInitContextVulkan::InitTexture	(	const ezGALTextureVulkan *	pTexture,
		vk::ImageCreateInfo &	createInfo,
		ezArrayPtr< ezGALSystemMemoryDescription >	pInitialData
	)

Initializes a texture and moves it into its default state.

Parameters

pTexture	The texture to initialize.
createInfo	The image creation info for the texture. Needed for initial state information.
pInitialData	The initial data of the texture. If not set, the initial content will be undefined.

UpdateBuffer()

void ezInitContextVulkan::UpdateBuffer	(	const ezGALBufferVulkan *	pBuffer,
		ezUInt32	uiOffset,
		ezConstByteArrayPtr	pSourceData
	)

Updates a buffer range.

Parameters

pBuffer	The buffer to update.
uiOffset	The offset inside the buffer where the new data should be placed.
pSourceData	The new data to update the buffer with.

UpdateDynamicUniformBuffer()

void ezInitContextVulkan::UpdateDynamicUniformBuffer	(	vk::Buffer	gpuBuffer,
		vk::Buffer	stagingBuffer,
		ezUInt32	uiOffset,
		ezUInt32	uiSize
	)

Used by ezUniformBufferPoolVulkan to write the entire uniform scratch pool to the GPU.

Parameters

gpuBuffer	The device local buffer to update.
stagingBuffer	The staging buffer that contains the data to be copied to gpuBuffer. If null, buffer is CPU writable and already contains the data.
uiOffset	Offset in the buffer.
uiSize	The size of the data to be copied from stagingBuffer to gpuBuffer.
