Detailed Description

Copyright (c) Theophilus Eriata. All Rights Reserved.

Internal view-local capture transport shared by scene picking consumers. It owns only pixel and view snapshots; callers retain the matching native owner metadata in three slot tables. CPU frame-boundary access only. No submission or GPU wait occurs in this facility.

Member Function Documentation

AddCapture()

xiiResult xiiScenePickingReadback::AddCapture	(	xiiRenderPipelinePassContext &	context,
		xiiRenderGraphTextureHandle	texture,
		xiiUInt32 &	out_uiReservedSlot )

Requires Poll first. Supports R32UInt and RGBA32UInt, both single-sample 2D textures. Success with InvalidIndex means backpressure or a resize draining old captures. At most three captures are retained, including during repeated resizing and format changes.

Poll()

xiiResult xiiScenePickingReadback::Poll

(

xiiUInt32 &

out_uiCompletedSlot

)

Publishes the newest completed image and returns its slot, or InvalidIndex when unchanged. Consume/swap that slot's metadata before AddCapture can reserve a slot again.
