Detailed Description

RenderPipeline describes how to render a scene. It has all the passes and views for rendering. A scene may have several pipelines. Each pipeline have its own render frequency. Pipeline can be disabled and it won't be rendered if it's disabled.

Member Function Documentation

◆ AddPassAfter()

bool AZ::RPI::RenderPipeline::AddPassAfter ( Ptr< Pass >  newPass,
const AZ::Name &  referencePassName 
)

Find a reference pass's location and add the new pass after the reference pass After the new pass was inserted, the new pass and the reference pass are siblings

◆ AddPassBefore()

bool AZ::RPI::RenderPipeline::AddPassBefore ( Ptr< Pass >  newPass,
const AZ::Name &  referencePassName 
)

Find a reference pass's location and add the new pass before the reference pass After the new pass was inserted, the new pass and the reference pass are siblings

◆ AddToRenderTick()

void AZ::RPI::RenderPipeline::AddToRenderTick ( )

Add this RenderPipeline to RPI system's RenderTick and it will be rendered whenever the RPI system's RenderTick is called. The RenderPipeline is rendered per RenderTick by default unless AddToRenderTickOnce() was called.

◆ AddToRenderTickOnce()

void AZ::RPI::RenderPipeline::AddToRenderTickOnce ( )

Add this RenderPipeline to the next RPI system's RenderTick and it will be rendered once. This function can be used for render a render pipeline with desired frequency as its associated window/view is expecting. Note: the RenderPipeline will be only rendered once if this function is called multiple time between two system ticks.

◆ AddTransientView()

void AZ::RPI::RenderPipeline::AddTransientView ( const PipelineViewTag &  viewId,
ViewPtr  view 
)

Add a view for a PipelineViewTag used in this pipeline. The view's reference will be only saved for rendering one frame and it will be cleared when the next frame starts. This function should be used after OnStartFrame is called.

◆ CreateRenderPipelineForImage()

static RenderPipelinePtr AZ::RPI::RenderPipeline::CreateRenderPipelineForImage ( const RenderPipelineDescriptor &  desc,
Data::Asset< AttachmentImageAsset >  imageAsset 
)
static

Create a render pipeline which renders to the specified attachment image The render pipeline's root pass is created from the pass template specified from RenderPipelineDescriptor::m_rootPassTemplate The input AttachmentImageAsset is used to connect to first output attachment of the root pass template Note: the AttachmentImageAsset doesn't need to be loaded

◆ FindFirstPass()

Ptr<Pass> AZ::RPI::RenderPipeline::FindFirstPass ( const AZ::Name &  passName)

Find the first pass with matching name in the render pipeline Note: to find all the passes with matching name in this render pipeline, use RPI::PassSystemInterface::Get()->ForEachPass() function instead.

◆ GetDefaultView()

ViewPtr AZ::RPI::RenderPipeline::GetDefaultView ( )

Get the view for the default view tag. It's the same as GetViews(GetMainViewTag()) and using first element.

◆ GetFirstView()

ViewPtr AZ::RPI::RenderPipeline::GetFirstView ( const PipelineViewTag &  viewTag)

Get the frist view for the view tag. It's the same as GetViews("tag") and using first element.

◆ SetDefaultStereoscopicViewFromEntity()

void AZ::RPI::RenderPipeline::SetDefaultStereoscopicViewFromEntity ( EntityId  entityId,
RPI::ViewType  viewType 
)

Set a stereoscopic view to the default view tag. It's the same as SetPersistentView(GetMainViewTag(), view)

◆ SetDefaultView()

void AZ::RPI::RenderPipeline::SetDefaultView ( ViewPtr  view)

Set a view to the default view tag. It's the same as SetPersistentView(GetMainViewTag(), view)

◆ SetPersistentView()

void AZ::RPI::RenderPipeline::SetPersistentView ( const PipelineViewTag &  viewId,
ViewPtr  view 
)

Assign a view for a PipelineViewTag used in this pipeline. This reference of this view will be saved until it's replaced in another SetPersistentView call.
