Procedual Planets

This is a blog post about my procedual planets. I'm not gonna put the github link as i'm not proud of the code. Although I guess nobody likes their old code :D.

Development

I worked on this on and off for about 8 months in 2020. I made it in unity.

This is a basic planet that just uses a heightmap and a colour shader. I followed this tutorial so I could figure out how to make procedual meshes.

Next I wanted fully 3D planets and i found cube marching.

I wasnt quite happy with the giant holes and how you cant see the planet from afar. So I implemented an octree structure. It was alot of work but I don't have many screenshots as it was mostly just errors.

I never got arround to fixing the errors and polishing it as at this point I had lost motivation for the project. But I still put some planets together to make a cool scene.
