Procedural skysphere

Controls : WS to roll up/down, AD to rotate clockwise/anticlockwise. Space to go forewards.

Prototype I put together in a couple of evenings to try out a few ideas that I was interested in, such as how source games render their skybox from a separate mini scene outside the map.

 It uses Vorenoi noise to generate a procedural starfield in the skybox, the gas giant texture is also procedural, using nested fractal-brownian-motion. This is rendered to a separate viewport texture and drawn on the skysphere, so you can't actually fly to the gas giant!
