Classes
struct	GPUSceneBlobWrite
	One deferred blob payload write: decode blob into the mapped destination dst. More...
struct	GSCurvePoint
struct	GSCurveSegment
struct	GPUSceneGeometry
struct	UploadGPURingBuffer< T >
struct	GPUSceneImpl
	All implementation state and machinery owned by GPUScene. More...
struct	GPUSceneImpl::TextureSlot
	Per-bindless-slot residency backing TextureHandle (one table per pool, since the 2D/3D pools have independent slot spaces). More...
struct	GPUSceneImpl::GeometryResidency
struct	GPUSceneImpl::PendingGeometryUpload
	A geometry resource reserved by Upload and finalized by Join / Poll. More...
struct	GPUSceneImpl::PendingTextureUpload
struct	GPUSceneImpl::PendingBufferUpload
	A plain device-local buffer copy; the payload is owned so the caller's source can go. More...
struct	GPUSceneImpl::OpenTables
struct	GPUSceneBlobDecodeJob
