WebGPU Material Slot Compiler

Interactive Three.js WebGPU/TSL demo for WebGPU Material Slot Compiler, with 6 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 3

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

P0Define and measure the target performance contract

The hero, city, distant 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.

P1Capture a current-source evidence bundle

Publish source-hash-bound renderer/backend facts, required diagnostic images, aligned readbacks, resource inventory, timing method, and limitations; directly inspect the important artifacts before promotion.
evidenceBundle
P2Close tier-specific acceptance

Validate and promote hero, city, distant as independent visual and performance contracts without crossing their protected invariants.
