after reading some of the threads here dealing with various ways of producing realistic clouds, I thought I might also give it a shot. The technique is based on the findings of http://ofb.net/%7Eeggplant/clouds/ (thanks Kernon ;))
It’s still a rather rough approach, no generally working solution. But I’ve only messed with it for about half an hour, so there is still room for improvement.
Still frame is here (full view plz, thumbnail looks sucky), animation will be posted when it has finished rendering (about 2.5 seconds per frame at 640x480)
edit: I also used only a single image as texture for the sprites, so forgive the sometimes repeating patterns
For animation, please see 2 posts below
