Clouds projected on a sphere. I had some time-lapse footage of sky from a previous project but it didn’t project so well I didnt want a sky rushing up and over the dome I wanted the dome to feel like it encapsulated the sky.
I also tried some perlin noise generated clouds and the just looked like noise. I wanted real puffy clouds. In my mockup I used some actual clouds and I was happy with that look.
The only solution was to build my own cloud generator, then I could controll speed and movement around the dome.
I used actual bits of real clouds and randomly cluster them into larger clouds that grow and deform as the move around a circle. This is then projected on to the dome giving me the effect I was after.
