Detailed Description

A pass that renders to the entire screen using a single triangle. This pass is designed to work without any dedicated geometry buffers and instead issues a 3-vertex draw and relies on the vertex shader to generate a fullscreen triangle from the vertex ids.

Member Function Documentation

◆ CompileResources()

void AZ::RPI::FullscreenTrianglePass::CompileResources ( const RHI::FrameGraphCompileContext context)

This function is called after compilation of the frame graph, but before execution. The provided FrameGraphAttachmentContext allows you to access RHI views associated with attachment ids. This is the method to build ShaderResourceGroups from transient attachment views.

Reimplemented from AZ::RHI::ScopeProducer.

◆ SetupFrameGraphDependencies()

void AZ::RPI::FullscreenTrianglePass::SetupFrameGraphDependencies ( RHI::FrameGraphInterface  frameGraph)

This function is called during the schedule setup phase. The client is expected to declare attachments using the provided


Implements AZ::RHI::ScopeProducer.
