Detailed Description

ScopeProducer is the base class for systems which produce scopes on the frame scheduler. The user is expected to inherit from this class and implement three virtual methods:

• SetupFrameGraphDependencies
• CompileResources
• BuildCommandList It can then be registered with the frame scheduler each frame. Internally, this process generates a Scope which is inserted to the frame graph internally.

EXAMPLE:

class MyScope : public RHI::ScopeProducer { public: MyScope() : RHI::ScopeProducer(RHI::ScopeId{"MyScopeId"}) {}

private: void SetupFrameGraphDependencies(FrameGraphInterface frameGraph) override { // Create attachments on the builder, use them. }

void CompileResources(const FrameGraphCompileContext& context) override { // Use the provided context to access image / buffer views and // build ShaderResourceGroups. }

void BuildCommandList(const FrameGraphExecuteContext& context) override { // A context is provided which allows you to access the command // list for execution. } };

MyScope scope;

// Register with the scheduler each frame. Callbacks will be // invoked. frameScheduler.AddScope(scope);

Constructor & Destructor Documentation

ScopeProducer()

AZ::RHI::ScopeProducer::ScopeProducer ( )

protected

Protected default constructor for classes that inherit from ScopeProducer but that can't supply a ScopeId at construction.

Member Function Documentation

InitScope()

void AZ::RHI::ScopeProducer::InitScope ( const ScopeId &  scopeId, HardwareQueueClass  hardwareQueueClass = HardwareQueueClass::Graphics  )

protected

Initializes the scope with a ScopeId and HardwareQueueClass. Used by classes that inherit from ScopeProducer but can't supply a ScopeId at construction.

SetScopeId()

void AZ::RHI::ScopeProducer::SetScopeId ( const ScopeId &  scopeId )

protected

DEPRECATED.

Deprecated:

Use InitScope instead
