side-by-side VS gaseous-giganticus

I think the curl noise paper is from 2007: https://www.cs.ubc.ca/~rbridson/docs/bridson-siggraph2007-cu...

I've used the basic idea from that paper to make a surprisingly decent program to create gas-giant planet textures: https://github.com/smcameron/gaseous-giganticus

Gaseous-giganticus - procedurally generates gas giant planet textures for space games, etc.

This is what gaseous-giganticus uses. Combined with some other techniques, it can help with making some clouds for earthlike planets, but not in real time. Mentioned here previously. The process I use for making earthlike planets with clouds for Space Nerds in Space is described here.

Here's my own gas giant thingy, which produces (what I imagine to be) decent results, but is quite slow.

Hi. I'm the author of gaseous-giganticus. You do not need to apply the patch, as it was incorporated into the source already a long time ago: https://github.com/smcameron/gaseous-giganticus/commit/b3ca95f2f3975d6ca97029dae166e2daf068b3f0

I needed some gas giant textures for planets in my space game so I made this thing, which also ended up getting used by other people for their Kerbal Space Program mods.

Is that gaseous-giganticus output that I spy?

I've made a couple. For gas giants, gaseous-giganticus. For earthlike, or rocky planets, there's a program called "earthlike.c" in the space-nerds-in-space repo. Other than allowing you to supply an input image to use more or less as a color palette, they don't allow much in terms of customization, though there are quite a few knobs you can turn.

Most innovative thing, or what I'm most astonished I actually successfully pulled off against all odds, is probably gaseous-giganticus, which is a program that uses curl noise for procedural fluid flow(pdf) on the surface of a sphere to create cubemap textures for procedurally generated gas giant planets.
