Detailed Description

Per-graph, single-threaded resource allocator that sits in front of the global ezRenderGraphResourcePool.

Each render graph owns one allocator. The allocator provides a simple AcquireTexture / ReleaseTexture API. Internally it tracks how many resources of each description are currently in use so that the same GPU resource is never handed out twice within a graph, while still sharing resources between graphs that happen to need the same description.

Released resources stay alive in the allocator for intra-graph recycling. FreeResources (or the destructor) drops all shared pointers, decrementing the ref counts back toward the pool.

Member Function Documentation

AcquireTexture()

ezGALTextureHandle ezRenderGraphResourceAllocator::AcquireTexture

(

const ezGALTextureCreationDescription &

desc

)

Acquire a texture matching the given description. If a previously released texture with the same description is available, it is recycled. Otherwise, a new slot is requested from the pool.

ReleaseTexture()

void ezRenderGraphResourceAllocator::ReleaseTexture

(

ezGALTextureHandle

hTexture

)

Return a texture for intra-graph recycling. The underlying pooled resource stays alive in the allocator; a future AcquireTexture with a matching description may return this same resource.
