Detailed Description

Cache of material SRBs indexed by their ordered logical texture slots. Acquire() is thread-safe and only reserves logical entries; Prepare() and SRB access are render-thread-only. Entries are owned by RadientMaterialSRBLease instances, and unused records are removed by Prepare().

Member Function Documentation

◆ Acquire() [1/2]

RadientMaterialSRBLease Diligent::RadientMaterialSRBTable::Acquire	(	const RadientMaterialTextureSRBSlot const	ppSlots,
		Uint32	SlotCount )

Thread-safely reuses or reserves an entry for a complete ordered slot recipe without retaining the supplied texture references on a cache hit.

◆ Acquire() [2/2]

RADIENT_STATUS Diligent::RadientMaterialSRBTable::Acquire	(	const RadientMaterialTextureSRBSlotArray &	MaterialTextures,
		PBR_Renderer::PSO_FLAGS	PSOFlags,
		Uint32	MaxTextureSlots,
		const RadientMaterialDefaultTextureBindings &	DefaultTextures,
		RadientMaterialSRBLease &	Lease,
		PBR_Renderer::StaticShaderTextureIdsArrayType &	ShaderTextureIds )

Thread-safely builds the material texture mapping and reuses or reserves the matching SRB entry without creating GPU objects. Slot texture references are only retained when a new entry is inserted.

◆ GetSize()

size_t Diligent::RadientMaterialSRBTable::GetSize ( ) const

noexcept

Returns the number of retained table records. Expired weak entries may remain included until the next Prepare() call removes them.

◆ Prepare()

RADIENT_STATUS Diligent::RadientMaterialSRBTable::Prepare	(	Uint32	TextureVersion,
		Uint32	MaterialBufferVersion,
		Uint64	MaterialBufferGeneration,
		const ResolveTextureSRVCallbackType &	ResolveTextureSRV,
		const CreateSRBCallbackType &	CreateSRB )

Creates new SRBs and recreates existing SRBs when the texture resources or shared material buffer change. Pending texture resolutions are skipped and retried by the next call.
