Detailed Description

The PipelineStateForDraw caches descriptor for RHI::PipelineState's creation so the RHI::PipelineState can be created or updated later when Scene's render pipelines changed or any other data in the descriptor has changed.

Member Function Documentation

Finalize()

const RHI::PipelineState * AZ::RPI::PipelineStateForDraw::Finalize

(

)

Re-create the RHI::PipelineState for the input Scene. The created RHI::PipelineState will be cached and can be acquired by using GetPipelineState()

GetRHIPipelineState()

const RHI::PipelineState * AZ::RPI::PipelineStateForDraw::GetRHIPipelineState

(

)

const

Get cached RHI::PipelineState. It triggers an assert if the pipeline state is dirty.

Init()

void AZ::RPI::PipelineStateForDraw::Init	(	const Data::Instance< Shader > &	shader,
		const ShaderOptionList *	optionAndValues = nullptr
	)

Initialize the pipeline state from a shader and one of its shader variant The previous data will be reset

InputStreamLayout()

RHI::InputStreamLayout & AZ::RPI::PipelineStateForDraw::InputStreamLayout

(

)

Return the reference of the pipeline state descriptor's m_inputStreamLayout which can be modified directly It sets this pipeline state to dirty whenever it's called. Use ConstDescriptor() to access read-only InputStreamLayout

RenderStatesOverlay()

RHI::RenderStates & AZ::RPI::PipelineStateForDraw::RenderStatesOverlay

(

)

Return the reference of the RenderStates overlay which will be applied to original m_renderState which are loaded from shader variant Use this function to modify pipeline states RenderStates. It sets this pipeline state to dirty whenever it's called. Use ConstDescriptor() to access read-only RenderStates

SetOutputFromScene()

void AZ::RPI::PipelineStateForDraw::SetOutputFromScene	(	const Scene *	scene,
		RHI::DrawListTag	overrideDrawListTag = RHI::DrawListTag()
	)

Update the pipeline state descriptor for the specified scene This is usually called when Scene's render pipelines changed

UpdateSrgVariantFallback()

bool AZ::RPI::PipelineStateForDraw::UpdateSrgVariantFallback

(

Data::Instance< ShaderResourceGroup > &

srg

)

const

Setup the shader variant fallback key to a shader resource group if the shader variant is not ready Return true if the srg was modified.
