Detailed Description

This feature processor manages Deferred DrawPackages for a Scene.

Member Function Documentation

Activate()

void AZ::Render::DeferredMaterialFeatureProcessor::Activate ( )

overridevirtual

Perform any necessary activation and gives access to owning Scene.

Reimplemented from AZ::RPI::FeatureProcessor.

AddModel()

void AZ::Render::DeferredMaterialFeatureProcessor::AddModel ( const ModelId &  uuid, ModelDataInstanceInterface *  meshHandle, const Data::Instance< RPI::Model > &  model  )

overridevirtual

Create a deferred draw-item for the referenced material types, if they don't exist yet.

Implements AZ::Render::DeferredMaterialFeatureProcessorInterface.

Deactivate()

void AZ::Render::DeferredMaterialFeatureProcessor::Deactivate ( )

overridevirtual

Perform any necessary deactivation.

Reimplemented from AZ::RPI::FeatureProcessor.

GetDrawPacketIdBuffer()

AZ::Data::Instance< AZ::RPI::Buffer > AZ::Render::DeferredMaterialFeatureProcessor::GetDrawPacketIdBuffer ( const RHI::DrawListTag &  drawListTag )

overridevirtual

A buffer with the DrawPacketId for the given deferred DrawListTag. This buffer contains one entry for every mesh in the scene, with the id of the deferred fullscreen-DrawItem that is responsible for that mesh. The buffer is kept in sync with the MeshInfoBuffer, and can be indexed using the meshInfoIndex.

Implements AZ::Render::DeferredMaterialFeatureProcessorInterface.

IsEnabled()

bool AZ::Render::DeferredMaterialFeatureProcessor::IsEnabled ( )

inlineoverridevirtual

Wheter Deferred rendering was enabled at startup, controlled by CVAR r_deferredRenderingEnabled.

Implements AZ::Render::DeferredMaterialFeatureProcessorInterface.

RemoveModel()

void AZ::Render::DeferredMaterialFeatureProcessor::RemoveModel ( const ModelId &  uuid )

overridevirtual

Removes a mesh and potentially the draw-item for the material type.

Implements AZ::Render::DeferredMaterialFeatureProcessorInterface.

Render()

void AZ::Render::DeferredMaterialFeatureProcessor::Render ( const RenderPacket &  )

overridevirtual

The feature processor should enqueue draw packets to relevant draw lists.

• This is called every frame.
• This may be called in parallel with other feature processors.
• This may be called in parallel with culling

Reimplemented from AZ::RPI::FeatureProcessor.
