I'm in Busan, though I didn't feel anything. (I was on the beach at the time though.)

Wow! I just checked your CV (we were at Cambridge at the same time :) ), and I will never dismiss a Geography degree again!

Hey, if you click through to one of the example simulations you'll be able to change the visualization from waves to time-averaged power density, which should be closer to what you're looking for.

Thanks! If you navigate to one of the example simulations, you'll be able to change the instantaneous field visualisation to one of time-averaged power density, which sounds closer to what you're looking for.

The cool thing about the speed of WebGPU is that you can drag things around and watch changes in real-time, even if you have to average lots of simulation steps per rendered frame.

Interesting! I have a desktop 3070 and hear the same. I don't hear anything on a Mac M1 though.

Definitely the vibe I'm going for!

Good question! This is actually a numerical solver for a few coupled partial differential equations - the method in this context (electromagnetism) is called FDTD. It's implemented as a WebGPU compute shader.

You absolutely could do this using WebGL2 compute shaders too, but I thought it would be fun to try this newer API.

Agreed! Though support should be coming soon it seems. As a complete WebGPU novice I was really impressed with how quick it was to get going.
