WebGPU Bounded Water

Interactive Three.js WebGPU/TSL demo for WebGPU Bounded Water, with 1 scenario, 6 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 5

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, 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.

P0Heightfield Readback runtime proof

presentation final/no-post/diagnostics RGBA8 readbacks captured; specialized heightfield storage probe remains residual for full acceptance.

P0Receiver Caustic Energy Readback runtime proof

GPU storage-buffer energy-closure probe required for full acceptance; not claimed on primary correctness lane.

P0Opaque Color Depth Without Water runtime proof

primary correctness presentation captured; specialized opaque-without-water pass proof residual for full acceptance.
