WebGPU Procedural Timelines

Interactive Three.js WebGPU/TSL demo for WebGPU Procedural Timelines, with 3 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.

  1. P0Define and measure the target performance contract

    The full, balanced, test-minimum 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.

  2. P0Current Adapter GPU Timestamp runtime proof

    timestampQueriesActive remains false for correctness profile; GPU timing is not accepted as performance evidence.

  3. P2Close tier-specific acceptance

    Validate and promote full, balanced, test-minimum as independent visual and performance contracts without crossing their protected invariants.
