virtual gpu::Texture	acquireFilterTexture (const gpu::TextureDescriptor &desc)=0
	Takes a filter intermediate matching desc from the renderer's pool, or an invalid texture when the renderer's budget refuses it.
virtual void	releaseFilterTextureAtFrameEnd (gpu::Texture texture, const gpu::TextureDescriptor &desc)=0
	Hands texture back for reuse once the frame it was recorded into has submitted.

Detailed Description

Renderer-owned allocation boundary for filter textures.

Filter work is recorded into the renderer's frame command encoder, so textures must remain unavailable for reuse until that frame submits. Implementations provide exact-descriptor pooling and defer releases to the frame boundary.

Member Function Documentation

acquireFilterTexture()

virtual gpu::Texture donner::geode::FilterTextureAllocator::acquireFilterTexture ( const gpu::TextureDescriptor & desc )

pure virtual

Takes a filter intermediate matching desc from the renderer's pool, or an invalid texture when the renderer's budget refuses it.

Parameters

desc	Descriptor the intermediate is allocated with.

releaseFilterTextureAtFrameEnd()

virtual void donner::geode::FilterTextureAllocator::releaseFilterTextureAtFrameEnd ( gpu::Texture texture, const gpu::TextureDescriptor & desc )

pure virtual

Hands texture back for reuse once the frame it was recorded into has submitted.

Parameters

texture	Texture to return; consumed.
desc	Descriptor texture was acquired with; must match, or the next acquire for that descriptor misses its bucket.
