The old implementation of the Harris code in fg was using hard coded cloud shape, hard coded cloud relative position between clouds, hard coded group of cloud around ksfo. The next implementation could do clouds everywhere on the planet, parametrable cloud shapes in an xml file (Harris was using a non editable binary format), parametrable cloud formation type. Wasn't that some kind of improvement ? What could have been improved then is some new texture for the cloud particles or new shapes or whatever, frankly anybody could enhance what I did. Hm wait, you did not realize that Harris clouds are *slow* and ppl on this list were using depreciated hardware... Using his method to render the clouds is very easy to integrate in our code.
