2. The clouds near the sun are glowing much brighter than clouds far from the sun.
3. Luckly the clouds are moving across the sky, and occasionally block out the sun, making it easier to see, so you don't have to squint as much.
4. The clouds are also changing shape as they move across the sky.
5. Not all the sky contains cloud. Some areas of sky are completely cloud free.
6. The clouds do not continue into the distance forever. The furthest clouds are often obscured by haze.
7. All of this used 29 pixel shader instructions to implement.
8. All of this are real-time on GPU that used only 1 noise 3d lookup texture even the sun is procedural.
9. I coded the cloud in 2 days with rendermonkey and integration to ogre.
enjoy it
