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: Accepted runtime evidence is available for the published contract represented by this demo.

Readiness & remaining fixes 1

Declared evidence work remains. Overall implementation status does not establish individual runtime or performance claims.

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.
