TypeGPU / WebGPU for HyperFrames

HyperFrames supports TypeGPU and raw WebGPU through its typegpu runtime adapter. The adapter does not own your pipeline. It publishes HyperFrames time and dispatches a seek event so your composition can render the exact GPU frame.

Contract

• Initialize WebGPU asynchronously (await navigator.gpu.requestAdapter()), but register all GSAP tweens synchronously — before any await. The HyperFrames player reads the timeline immediately at page load.
• Render from HyperFrames time, not performance.now().
• Listen for the hf-seek event and re-render at exactly that time.
• Guard against environments where WebGPU is unavailable — the adapter does not check for you.
• For video renders, call await device.queue.onSubmittedWorkDone() after submitting GPU work to ensure the canvas is flushed before the frame is captured.

The adapter sets window.__hfTypegpuTime and dispatches new CustomEvent("hf-seek", { detail: { time } }) on each seek.
