Detailed Description

template<typename Handle>
struct MayaFlux::Kinesis::Vision::VisionPass< Handle >

State threaded through one execution of a VisionSequence.

Shared by the CPU and GPU executors so op functions have one signature on both paths. Three bands: the walk, working storage, and redundancy caches.

Cross-run retained state is not here. It is owned vectors on the CPU path and owned images on the GPU path, neither of which is a working storage handle, so each executor holds its own in its own types.

Template Parameters

Handle

Working storage handle. Slot index on the CPU path, shared_ptr<VKImage> on the GPU path.

sequence is non-owning and valid only for the run that constructed the pass. Storage and caches outlive a single run once the pass is held by the executor; the walk band is reset per run by begin().
