Texture allocation API

Allocate texture handle (encapsulates texture and sampler object, memory request and callback to shader).

The actual allocation of the associated GPU texture and sampler resources and loading of the texture file is delayed until the commit phase.

Parameters

textureId	Path to file and information to identify a texture if the file is a container for several textures (e.g., OpenVDB file containing several grids, movie file containing frames).
textureType	Texture type, e.g., uv, ptex, ...
samplerParams	Sampling parameters such as wrapS, ... wrapS, wrapT, wrapR mode, min filer, mag filter
memoryRequest	Memory request. The texture is down-sampled to meet the target memory which is the maximum of all memory requests associated to the texture. If all memory requests are 0, no down-sampling will happen.
shaderCode	After the texture is committed (or after it has been changed) the given shader code can add additional buffer sources and computations using the texture metadata with AddResourcesFromTextures.

HDST_API HdStTextureObjectSharedPtr HdStResourceRegistry::AllocateTextureObject	(	const HdStTextureIdentifier &	textureId,
		HdTextureType	textureType
	)

Allocate texture object.

The actual allocation of the associated GPU texture and sampler resources and loading of the texture file is delayed until the commit phase.

Parameters

textureId	Path to file and information to identify a texture if the file is a container for several textures (e.g., OpenVDB file containing several grids, movie file containing frames).
textureType	Texture type, e.g., uv, ptex, ...

)

Remove any entries associated with expired dispatch buffers.

The returned pointer should not be held onto by the client as it is only valid until the HgiBlitCmds has been submitted.

HDST_API HgiComputeCmds* HdStResourceRegistry::GetGlobalComputeCmds

(

HgiComputeDispatch

dispatchMethod = HgiComputeDispatchSerial

)

Returns the global hgi compute cmd queue for recording compute work. When using this global cmd instead of creating a new HgiComputeCmds we reduce the number of command buffers being created. The returned pointer should not be held onto by the client as it is only valid until the HgiComputeCmds has been submitted.

HDST_API Hgi* HdStResourceRegistry::GetHgi

Instance Registries

These registries implement sharing and deduplication of data based on computed hash identifiers. Each returned HdInstance object retains a shared pointer to a data instance. When an HdInstance is registered for a previously unused ID, the data pointer will be null and it is the caller's responsibility to set its value. The instance registries are cleaned of unreferenced entries during garbage collection.

Note: As entries can be registered from multiple threads, the returned object holds a lock on the instance registry. This lock is held until the returned HdInstance object is destroyed.

HDST_API HdInstance<HdBufferArrayRangeSharedPtr> HdStResourceRegistry::RegisterPrimvarRange

(

HdInstance< HdBufferArrayRangeSharedPtr >::ID

id

)

Primvar array range instancing Returns the HdInstance pointing to shared HdBufferArrayRange, distinguished by given ID. *Refer the comment on RegisterTopology for the same consideration.

HDST_API HdInstance<HgiResourceBindingsSharedPtr> HdStResourceRegistry::RegisterResourceBindings

(

HdInstance< HgiResourceBindingsSharedPtr >::ID

id

)

Register a Hgi resource bindings into the registry.

HDST_API void HdStResourceRegistry::ReloadResource ( TfToken const &  resourceType, std::string const &  path  )

overridevirtual

Generic method to inform RenderDelegate a resource needs to be reloaded. This method can be used by the application to inform the renderDelegate that a resource, which may not have any prim representation in Hydra, needs to be reloaded. For example a texture found in a material network. The path can be absolute or relative. It should usually match the path found for textures during HdMaterial::Sync.

Reimplemented from HdResourceRegistry.

HDST_API void HdStResourceRegistry::SetMemoryRequestForTextureType	(	HdTextureType	textureType,
		size_t	memoryRequest
	)

Sets how much memory a single texture can consume in bytes by texture type.

Only has an effect if non-zero and only applies to textures if no texture handle referencing the texture has a memory request.

HDST_API void HdStResourceRegistry::SubmitBlitWork

(

HgiSubmitWaitType

wait = HgiSubmitWaitTypeNoWait

)

Submits blit work queued in global blit cmds for GPU execution. We can call this when we want to submit some work to the GPU. To stall the CPU and wait for the GPU to finish, 'wait' can be provided. To insert a barrier to ensure memory writes are visible after the barrier a HgiMemoryBarrier can be provided.

HDST_API void HdStResourceRegistry::SubmitComputeWork

(

HgiSubmitWaitType

wait = HgiSubmitWaitTypeNoWait

)

Submits compute work queued in global compute cmds for GPU execution. We can call this when we want to submit some work to the GPU. To stall the CPU and wait for the GPU to finish, 'wait' can be provided. To insert a barrier to ensure memory writes are visible after the barrier a HgiMemoryBarrier can be provided.

BAR allocation/migration/update API

The Update* flavor of methods handle both allocation of a new BAR and reallocation-migration based on the existing range, updated/added specs, removed specs and usage hint. This allows client code to be less verbose when a range's signature (specs) can change.

If curRange is invalid, this is equivalent to calling Allocate*. Otherwise, checks if curRange needs to be migrated to a new range (based on updatedOrAddedSpecs and removedSpecs and usageHint). If migration is necessary, allocate a new range and register necessary migration computations and return the new range. Otherwise, just return the same range.
