Personal project - a planet generator using some simple noise textures and a very large and slow shader.

Done mostly to see if I could generate something that looked good and felt somewhat realistic as a planet generator entirely in a shader.

The shader works by sampling a few different 3D noise textures to generate temperature, humidity, and height textures. It uses these to pick between different biome colors and generate a normal for the surface derived from the height.

Earth-like planet - light is generated on the dark side using a population slider.

A cold planet with a high ocean level.

It can also generate Mercator-projection maps.

A high temperature island world.

Or generate entirely alien planets!

Or more realistic chunks of rock...
