Detailed Description

HdStRenderDelegate

The Storm Render Delegate provides a rasterizer renderer to draw the scene. While it currently has some ties to GL, the goal is to use Hgi to allow it to be graphics API agnostic.

Member Function Documentation

HDST_API void HdStRenderDelegate::CommitResources ( HdChangeTracker * tracker )

overridevirtual

Sync, Execute & Dispatch Hooks Notification point from the Engine to the delegate. This notification occurs after all Sync's have completed and before task execution.

This notification gives the Render Delegate a chance to update and move memory that the render may need.

For example, the render delegate might fill primvar buffers or texture memory.

Implements HdRenderDelegate.

HDST_API HdBprim* HdStRenderDelegate::CreateBprim	(	TfToken const &	typeId,
		SdfPath const &	bprimId
	)

overridevirtual

Request to Allocate and Construct a new Bprim.

Parameters

typeId	the type identifier of the prim to allocate
sprimId	a unique identifier for the prim

Returns: A pointer to the new prim or nullptr on error.

Implements HdRenderDelegate.

HDST_API HdBprim* HdStRenderDelegate::CreateFallbackBprim ( TfToken const & typeId )

overridevirtual

Request to Allocate and Construct a Bprim to use as a standin, if there if an error with another another Bprim of the same type. For example, if another prim references a non-exisiting Bprim, the fallback could be used.

Parameters

typeId the type identifier of the prim to allocate

Returns: A pointer to the new prim or nullptr on error.

Implements HdRenderDelegate.

HDST_API HdSprim* HdStRenderDelegate::CreateFallbackSprim ( TfToken const & typeId )

overridevirtual

Request to Allocate and Construct an Sprim to use as a standin, if there if an error with another another Sprim of the same type. For example, if another prim references a non-exisiting Sprim, the fallback could be used.

Parameters

typeId the type identifier of the prim to allocate

Returns: A pointer to the new prim or nullptr on error.

Implements HdRenderDelegate.

HDST_API HdInstancer* HdStRenderDelegate::CreateInstancer	(	HdSceneDelegate *	delegate,
		SdfPath const &	id
	)

overridevirtual

Instancer Factory Request to create a new instancer.

Parameters

id	The unique identifier of this instancer.

Returns: A pointer to the new instancer or nullptr on error.

Implements HdRenderDelegate.

HDST_API HdRenderPassSharedPtr HdStRenderDelegate::CreateRenderPass	(	HdRenderIndex *	index,
		HdRprimCollection const &	collection
	)

overridevirtual

Renderpass Factory Request to create a new renderpass.

Parameters

index	the render index to bind to the new renderpass.
collection	the rprim collection to bind to the new renderpass.

Returns: A shared pointer to the new renderpass or empty on error.

Implements HdRenderDelegate.

HDST_API HdRenderPassStateSharedPtr HdStRenderDelegate::CreateRenderPassState ( ) const

overridevirtual

Request to create a new renderpass state. The default implementation creates an HdRenderPassState instance, but derived render delegates may instantiate their own state type.

Parameters

shader The render pass shader to use. If null, a new HdRenderPassShared will be created.

Returns: A shared pointer to the new renderpass state.

Reimplemented from HdRenderDelegate.

HDST_API HdRprim* HdStRenderDelegate::CreateRprim	(	TfToken const &	typeId,
		SdfPath const &	rprimId
	)

overridevirtual

Prim Factories Request to Allocate and Construct a new Rprim.

Parameters

typeId	the type identifier of the prim to allocate
rprimId	a unique identifier for the prim

Returns: A pointer to the new prim or nullptr on error.

Implements HdRenderDelegate.

HDST_API HdSprim* HdStRenderDelegate::CreateSprim	(	TfToken const &	typeId,
		SdfPath const &	sprimId
	)

overridevirtual

Request to Allocate and Construct a new Sprim.

Parameters

typeId	the type identifier of the prim to allocate
sprimId	a unique identifier for the prim

Returns: A pointer to the new prim or nullptr on error.

Implements HdRenderDelegate.

HDST_API void HdStRenderDelegate::DestroyBprim ( HdBprim * bprim )

overridevirtual

Request to Destruct and deallocate the prim.

Implements HdRenderDelegate.

HDST_API void HdStRenderDelegate::DestroyInstancer ( HdInstancer * instancer )

overridevirtual

Implements HdRenderDelegate.

HDST_API void HdStRenderDelegate::DestroyRprim ( HdRprim * rPrim )

overridevirtual

Request to Destruct and deallocate the prim.

Implements HdRenderDelegate.

HDST_API void HdStRenderDelegate::DestroySprim ( HdSprim * sprim )

overridevirtual

Request to Destruct and deallocate the prim.

Implements HdRenderDelegate.

HDST_API HdAovDescriptor HdStRenderDelegate::GetDefaultAovDescriptor ( TfToken const & name ) const

overridevirtual

AOVs Returns a default AOV descriptor for the given named AOV, specifying things like preferred format.

Reimplemented from HdRenderDelegate.

HDST_API HdStDrawItemsCachePtr HdStRenderDelegate::GetDrawItemsCache ( ) const

HDST_API Hgi* HdStRenderDelegate::GetHgi ( )

HDST_API TfTokenVector HdStRenderDelegate::GetMaterialRenderContexts ( ) const

overridevirtual

Returns a list, in descending order of preference, that can be used to select among multiple material network implementations. The default list contains an empty token.

Reimplemented from HdRenderDelegate.

HDST_API HdRenderParam* HdStRenderDelegate::GetRenderParam ( ) const

overridevirtual

Returns an opaque handle to a render param, that in turn is passed to each prim created by the render delegate during sync processing. This avoids the need to store a global state pointer in each prim.

The typical lifetime of the renderParam would match that of the RenderDelegate, however the minimal lifetime is that of the Sync processing. The param maybe queried multiple times during sync.

A render delegate may return null for the param.

Reimplemented from HdRenderDelegate.

HDST_API HdRenderSettingDescriptorList HdStRenderDelegate::GetRenderSettingDescriptors ( ) const

overridevirtual

Get the backend-exported render setting descriptors.

Reimplemented from HdRenderDelegate.

HDST_API VtDictionary HdStRenderDelegate::GetRenderStats ( ) const

overridevirtual

Returns an open-format dictionary of render statistics

Reimplemented from HdRenderDelegate.

HDST_API HdResourceRegistrySharedPtr HdStRenderDelegate::GetResourceRegistry ( ) const

overridevirtual

Returns a shared ptr to the resource registry of the current render delegate.

Implements HdRenderDelegate.

HDST_API TfTokenVector HdStRenderDelegate::GetShaderSourceTypes ( ) const

overridevirtual

Returns the ordered list of shader source types that the render delegate supports.

Reimplemented from HdRenderDelegate.

HDST_API const TfTokenVector& HdStRenderDelegate::GetSupportedBprimTypes ( ) const

overridevirtual

Returns a list of typeId's of all supported Bprims by this render delegate.

Implements HdRenderDelegate.

HDST_API const TfTokenVector& HdStRenderDelegate::GetSupportedRprimTypes ( ) const

overridevirtual

Returns a list of typeId's of all supported Rprims by this render delegate.

Implements HdRenderDelegate.

HDST_API const TfTokenVector& HdStRenderDelegate::GetSupportedSprimTypes ( ) const

overridevirtual

Returns a list of typeId's of all supported Sprims by this render delegate.

Implements HdRenderDelegate.

HDST_API bool HdStRenderDelegate::IsPrimvarFilteringNeeded ( ) const

overridevirtual

Return true to indicate that the render delegate wants rprim primvars to be filtered by the scene delegate to reduce the amount of primvars that are send to the render delegate. For example the scene delegate may check the bound material primvar requirements and send only those to the render delegate. Return false to not apply primvar filtering in the scene delegate. Defaults to false.

Reimplemented from HdRenderDelegate.

static HDST_API bool HdStRenderDelegate::IsSupported ( )

static

HDST_API void HdStRenderDelegate::SetDrivers ( HdDriverVector const & drivers )

overridevirtual

Set list of driver objects, such as a rendering context / devices. This is automatically called from HdRenderIndex when a HdDriver is provided during its construction. Default implementation does nothing.

Reimplemented from HdRenderDelegate.
