Clouds have three requirements:
- They have to be randomly genorated
- They have to be completely 3d, as in you can fly through them
- They have to be beleivable as clouds
And I beleive that I've acheived all of those quite efficiently,
What I used for rendering the clouds I genorate with a rather simple algorithm I just pulled out of my ass, is a particle system. Each cloud is a particle system for which I had to write a particle emitter addon for OGRE and all.
Ok enough rambling... A few days and plenty of bugfixes later I ended up with this:
The clouds vary in size, shape, number of particles, and particle opacity.
And just for the record, you should have seen me freak out when I saw that one of the clouds looked like a dog. It went something like, "OMFG this cloud looks like a DOG and real clouds sometimes look like stuff!!!131E@!$q123"
EDIT: that screenshot's about a day out of date, the clouds look a bit better now, but not much I can do without stepping into the land of light scattering =P.
