w = g-g*exp(-mix(h*3e2,d*2.5,a=h<.001?0.:1.))
w = g-g/exp(mix(h*3e2,d*2.5,a=h<.001?0.:1.))If you see a way to make it shorter, feel free to share :)
w=g-g*exp(...),g-=w*a,c+=w*a*d*9.+...,c.r+=w*a*a*2,...
w=g-g*exp(...),g-=w*=a,c+=w*d*9.+...,c.r+=w*a*2,...
But! You can save 1 char by replacing w with a:
g -= a*=w,
c += a*d*9.+...
a = min(...),
c.r += w*a*a*.2,
(d==0.?K*.01*h:c-c)
(d>0.?.0:.01)*K*hI added your changes to the Shadertoy version with your HN nickname. I'll integrate it to the original later.
Thanks!
It seems that leaving the obsession behind some more can save another byte.

The code on the blog is pretty simple and naive (I'm not a webdev): https://github.com/ubitux/scripts/blob/main/share/blog/shade...
Any suggestion on how to address the issue is welcome.
Note: I don't have any Windows machine to test with

If you want to make your own solution there's one listed here about 1/2 way down the page
https://webglfundamentals.org/webgl/lessons/webgl-multiple-v...
As an aside, WebGPU doesn't have this issue or at least has it less. For one, WebGPU can use a single device to render to multiple canvases, something WebGL can't. Another is that WebGPU is mostly stateless making it easier for both the user and the browser.

What am I saying? Fine? It's freaking awesome.
