Native WebGPU Dense Grass

Interactive Three.js WebGPU/TSL demo for Native WebGPU Dense Grass, with 7 scenarios, 3 mechanisms, and 4 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 dense/ultra, dense/high, dense/medium, dense/low 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.
