AddOitBufferBindings()

HDX_API bool AddOitBufferBindings

(

const HdStRenderPassShaderSharedPtr &

)

Called during Execute to add necessary OIT buffer shader bindings.

Returns false if the OIT buffers were not allocated.

AllocateOitBuffersIfNecessary()

HDX_API void AllocateOitBuffersIfNecessary

(

HdRenderIndex *

renderIndex

)

Called during Prepare to allocate OIT bars if not yet in context.

Bars are initially unsized; call ResizeOitBuffersIfNecessary to size them.

InitializeOitBuffersIfNecessary()

HDX_API void InitializeOitBuffersIfNecessary

(

Hgi *

hgi

)

Called during Excecute before writing to OIT buffers.

RequestOitBuffers()

HDX_API void RequestOitBuffers

(

)

Called during Prepare to indicate that OIT buffers are needed.

ResizeOitBuffersIfNecessary()

HDX_API bool ResizeOitBuffersIfNecessary	(	HdRenderIndex *	renderIndex,
		GfVec2i const &	screenSize,
		GfVec2i *	prevScreenSize )

Called during Prepare (by OitResolveTask) to grow OIT bars to fit the current screen.

prevScreenSize is updated in-place and must be persisted by the caller across frames. Returns false if "screenSize" is invalid.
