2d dynamic clouds

[yan]

Hi monkeys.

I’m so fascinated with GLSLs these days. Today I read an article about 2D dynamic clouds by Inigo Quilez. Then I tried to write a simple exmaple with his idea, and want to share with you.

It’s simply combined with 4 noise texture. The clouds can move and change shape as time pass by.

The problem I’m facing now is that I don’t know how to generate tile-able noise map. I use 4 simplex noise instead, which make the clouds looks strange.

I’m now reading these articles, hope I can make it better.

How do you generate tileable Perlin noise?

At last, this is the source.

Reminds me of a project I worked on a couple of years ago. Maybe you find something useful:

Hey! First a bit of background. I’m a huge Elite and space sim fan! Sometimes i get cravings to play First Encounters again, but usually when i do, i get so disappointed by how primitive it is nowadays and don’t get very far. A while back i got this urge again, and decided to check what else is out there. I found this: http://pioneerspacesim.net/ An open source “clone”, or something similar, of First Encounters. Rather than playing it, i went on and checked some youtube vids of someone play…

Seems the formatting has broken down since, though.

Edit: I see now that I didn’t use noise, but a texture instead as source.
