I know, I know, I have some kind of severe ascii fluid sim addiction but I'm trying to build the once-and-for-all version and god damn this shit lookin good.

it's definitely expensive to do in 3D. it can be done though you just have to reduce the sim resolution. the other hard part of 3D is how to actually visualize it so it doesn't become a mess although additive blending and transparency works okay

Heeey, could you maybe use audio waveforms as input for this? If this is not your interest I'll keep an eye out for any kind of release or OSS; this looks quite cool

I love doing audio reactive shaders and I've thought about adding it to this but I don't really have good idea for how exactly to make this react unless I completely replace the fluid sim with like a frequency analyzer or something

First thing I'd try is just using amplitude to affect the movement of your main point — like, with silence it just tools along slowly left to right, loops back when it leaves the frame (same angle). Then greater audio amplitude = speed up, and with any big pulse, change angle (either direction)

Still hypnotized by that video you posted! Very interesting project, especially with the potential of sound reactivity as I’ve seen mentioned in some of the other threads
