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	(	HdStRenderPassStateSharedPtr const &	renderPassState,
		HdStResourceRegistrySharedPtr const &	resourceRegistry
	)

Execute the command buffer.

HDST_API void HdStCommandBuffer::FrustumCull ( GfMatrix4d const & cullMatrix )

Cull drawItemInstances based on passed in combined view and projection matrix.

size_t HdStCommandBuffer::GetCulledSize ( ) const

inline

Returns the number of culled draw items.

Definition at line 102 of file commandBuffer.h.

size_t HdStCommandBuffer::GetTotalSize ( ) const

inline

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

Definition at line 96 of file commandBuffer.h.

size_t HdStCommandBuffer::GetVisibleSize ( ) const

inline

Returns the number of draw items, excluding culled items.

Definition at line 99 of file commandBuffer.h.

HDST_API void HdStCommandBuffer::PrepareDraw	(	HdStRenderPassStateSharedPtr const &	renderPassState,
		HdStResourceRegistrySharedPtr const &	resourceRegistry
	)

Prepare the command buffer for draw.

HDST_API void HdStCommandBuffer::RebuildDrawBatchesIfNeeded ( unsigned currentBatchVersion )

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

HDST_API void HdStCommandBuffer::SetEnableTinyPrimCulling ( bool tinyPrimCulling )

HDST_API void HdStCommandBuffer::SwapDrawItems	(	std::vector< HdStDrawItem const * > *	items,
		unsigned	currentBatchVersion
	)

Destructively swaps the contents of items with the internal list of all draw items. Culling state is reset, with no items visible.

HDST_API void HdStCommandBuffer::SyncDrawItemVisibility ( unsigned visChangeCount )

Sync visibility state from RprimSharedState to DrawItemInstances.
