Detailed Description

A buffer of commands (HdStDrawItem or HdComputeItem objects) to be executed.

The HdStCommandBuffer is responsible for accumulating draw items and sorting them for correctness (e.g. alpha transparency) and efficiency (e.g. the fewest number of GPU state changes).

HDST_API void HdStCommandBuffer::ExecuteDraw	(	HgiGraphicsCmds *	gfxCmds,
		HdStRenderPassStateSharedPtr const &	renderPassState,
		HdStResourceRegistrySharedPtr const &	resourceRegistry
	)

Execute the command buffer.

size_t HdStCommandBuffer::GetCulledSize ( ) const

inline

Returns the number of culled draw items.

Definition at line 110 of file commandBuffer.h.

size_t HdStCommandBuffer::GetTotalSize ( ) const

inline

Returns the total number of draw items, including culled items.

Definition at line 101 of file commandBuffer.h.

size_t HdStCommandBuffer::GetVisibleSize ( ) const

inline

Returns the number of draw items, excluding culled items.

HDST_API void HdStCommandBuffer::PrepareDraw	(	HgiGraphicsCmds *	gfxCmds,
		HdStRenderPassStateSharedPtr const &	renderPassState,
		HdRenderIndex *	renderIndex
	)

Prepare the command buffer for draw.

HDST_API void HdStCommandBuffer::RebuildDrawBatchesIfNeeded	(	unsigned	currentBatchVersion,
		HgiCapabilities const *	hgiCapabilities
	)

Rebuild all draw batches if any underlying buffer array is invalidated.

HDST_API void HdStCommandBuffer::SetDrawItems	(	HdDrawItemConstPtrVectorSharedPtr const &	drawItems,
		unsigned	currentBatchVersion,
		HgiCapabilities const *	hgiCapabilities
	)

Sets the draw items to use for batching. If the shared pointer or version is different, batches are rebuilt and the batch version is updated.

HDST_API void HdStCommandBuffer::SetEnableTinyPrimCulling ( bool tinyPrimCulling )

HDST_API void HdStCommandBuffer::SyncDrawItemVisibility ( unsigned visChangeCount )

Sync visibility state from RprimSharedState to DrawItemInstances.
