Hi,
I was wondering if someone has an algorithm for a cloud generator?
Cloudless in Columbus

You could use a few bitmaps of clouds (preferably with alpha) and use the iterator to move/scale/randomise them.

You could do a similar thing with the star field though each cloud would be the same.

You could look for a GL shader with appropriate licence.

For realistic clouds the preferred solution is to video record some clouds.

Thank you!
