WebGPU Node GTAO

Interactive Three.js WebGPU/TSL demo for WebGPU Node GTAO, with 7 scenarios, 6 mechanisms, and 3 quality tiers and evidence-gated validation.

Evidence status: The implementation is available for technical review, but its native-WebGPU runtime and evidence gates remain incomplete.

Readiness & remaining fixes 5

5 open closure items. Loadable does not mean accepted or performance-valid.

P0Define and measure the target performance contract

The ultra, high, medium tiers have no accepted frame target. Record named device/browser/GPU, viewport, DPR, sustained CPU/GPU/presentation p50 and p95, deadline misses, memory, and settled quality. Submission time is not GPU timing.

P0One Prepass One Lit Pass runtime proof

Capture current-source evidence for the declared one prepass one lit pass gate.

P0Current Adapter GPU Timestamps runtime proof

capture-status.gpuTimingVerdict remains INSUFFICIENT_EVIDENCE; no named-adapter timestamp ledger was accepted.

P2Close tier-specific acceptance

Validate and promote ultra, high, medium as independent visual and performance contracts without crossing their protected invariants.
