Show HN: a Rust ray tracer that runs on any GPU – even in the browser

In Safari 26 on an M1 with WebGPU enabled I get "InvalidStateError: GPUCommandEncoder.beginComputePass: Unable to begin compute pass."

In Chrome I get "Failed to start: Failed to create State. Caused by: failed to find GPU adapter."

So I guess it runs on "some" GPUs, in "some" browsers!

Works fine on M4. M1 didn't have mesh shaders, maybe that's why?

And on M5 Safari 26, jacking the samples/pixel setting up high seems to trigger a system reboot, which is most curious
