Very cool (note that you can place the light and drag it's direction)!

One thing I noticed is that this visualizes how dangerous laser light can be. A lot of DIY projects these days use lasers (SLA printers, Laser cutters). You can't warn people enough about the risks when working with lasers.

This app shows how laser light bounces around in ways you don't expect.

Edit: and ofcourse the rest of his portfolio is great: https://benedikt-bitterli.me/portfolio.html

The consolation image entirely made up for the fact that this doesn't run on my phone.

The usual WebGL demos that never match native experience.

My mobile devices do OpenGL ES 3.0 and 3.1, none of them runs the demo.

Floating point textures seem to be a particular weak point with WebGL on mobile devices. I don't understand why, though, as the devices I looked at actually support them with native apps (they're in the ES3 spec), but not with WebGL.

Yeah.

"Your platform does not support float textures. This demo won't run in your browser."

Nexus 5, Chrome

Doesn't run on mine as well, something about float textures

So apparently the classic Dark Side Of The Moon album cover isn't physically possible after all.

Not necessarily. We don't know what the index of refraction is on the prism on the album cover, nor even if the whole prism has a constant refraction index, or even if it's solid. But yes, the artist probably didn't depict it based on science.

Tip: don't set it to 4096x2160 unless you know what you're doing.

I tried and it takes a lot longer to render but cpu didn't pass 19%.

I get the following error message: Your platform does not support the draw buffers extension. This demo won't run in your browser

Both in regular Chrome and in Canary. Why?
