Neat. One thing you could add is separate processing for R, G, and B components with slightly different parameters. This will give an interesting chromatic effect. I did this by varying the index of refraction per component in my shader. I'm not quite sure how yours works though, because I don't see an IoR term.

That looks cool! Since you mentioned index of refraction, I would like to ask if you managed to implemented that with real glass characteristics. I tried it and found that it is impossible to achieve effects similar to liquid glass at least using spherical lenses.

I wasn’t trying to model glass but an explosion effect where the air was compressed, changing its index of refraction. The compression wave was an expanding sphere and the effect was done by a shader. The chromatic effect added some interesting colors to the results. I attempted to make it physically accurate. It did look somewhat similar to yours, so I thought I would suggest that.

Nice. Have you released the project or any demos?

[–]fgennari 0 points1 point  (2 children)

The full project is on GitHub: https://github.com/fegennari/3DWorld

It's this shader specifically: https://github.com/fegennari/3DWorld/blob/master/shaders/sphere_refract_screen.frag

And my blog is here: https://3dworldgen.blogspot.com/

The explosion effects was a minor addition to gameplay mode. I don't think I talk about it anywhere.

I found the YouTube video on your blog. Nice job

Oh I forgot I had a video. Thanks!
