TSL Procedural PBR

Interactive Three.js WebGPU/TSL demo for TSL Procedural PBR, 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 15

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

  1. P0Define and measure the target performance contract

    The ultra, high, mobile 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.

  14. 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.

  15. P2Close tier-specific acceptance

    Validate and promote ultra, high, mobile as independent visual and performance contracts without crossing their protected invariants.
