Hm... build checks think that Any browser that implements WebGPU will also have this API, so I think it's a non-issue. I'll look into how to suppress that error later, probably Monday. |
It was removed in TypeScript 4.4 Should just need to upgrade to 4.9 or newer. |

Done. updated to the last 4.x revision (4.9.5) |

This is a pretty simple sample, but it's covering a subject that I've seen a couple of questions about and I think i's useful to have readily available as a sanity check to ensure this method of using WebGPU works.
The sample itself is basically just a copy of the rotating cube sample, but with all the WebGPU code executing from a worker rather than the main thread.
canvas.transferToOffscreen()is used to produce anOffscreenCanvason the main thread that's then transferred to the worker and used for rendering. The frame loop is managed worker-side withrequestAnimationFrame().If we feel it's useful we could set up variants/options for this sample that use the
transferToImageBitmap()pattern for rendering and a main-thread-driven rendering loop, but I think it's probably OK to have it focus on simply demonstrating that you can use WebGPU in a worker.
