Cool. If you want to try rendering some flame fractals, you can try our Fractal software Chaotica (https://www.chaoticafractals.com/) which was used to make the first image in the linked post (Vorpol Dawn By technochroma).

We didn't exactly use compute shaders for Chaotica, we used OpenCL instead, which is a more general GPGPU framework like CUDA.

Oh hey Nick, fancy seeing you here :)

Honestly, this is such a good rewrite of Apophysis. Congrats to you all for bringing back some happy memories.

Fractal creative method of choice >^•¥•^<

I love the look of flame fractals, but I never figured out how to tweak things to get them to look more like how I want. I could never predict what a particular change would do to the look, or which change is needed to get a particular look.

I tried Apophysis (or one of the many spinoffs), but it never quite clicked.

Here's a web editor that has a fairly simple interface: https://fractalar-app.web.app

It might not run very well depending on your hardware, though.

Fractal flames is such a cool algorithm. They're what got me into programming many moons ago :)

Oh wow, it really has been many moons! You might recall a guy called lycium/lyc from those days :D

We're lurking on Discord these days, there are some new people from Austria sometimes joining our meetups, you should come along :)

Got a link to that Discord group?

Do you remember the email you sent me 12 years and 1 month ago, in which (among much other unhinged stuff) you called me a nazi because I mentioned I'm (part) German? I remembered your name; hello again! I see your project didn't go anywhere, that's too bad. I'm sure you'll understand if I decline to invite you to my Discord server :)

Haha hey lyc! I didn't forget, you guys were second family! You taught me a lot about maths and code, not sure where I'd be without you :) Learnt more while messing around with fractals and gfx than in all my time at uni.

Honestly I try not doing much computer stuff in my free time because I'm doing so much in my day to day but I'll stop by some time! I've been in the Chaotica discord for years but never said hello.

That's kind of you to say, and I'd love to meet up sometime just for the lolz, it's really far too close (with lots of other cool fractal ppl nearby) not to :)

This bring back memories of Apophysis
