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.

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

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.
