    Hey everyone, decided i'm going to try something new...
    My latest involves generating a massive planet using procedural noise and texturing...
    My question to all the geniuses on here, how do i go about generating the planet in the first place?
    Can I use a Sphere? but then i will probably need some sort of gravity?
    Or would a some sort of mesh work better?

    Any help is appreciated!:)

    Your first and best direction (imo) would be geodesic sphere displaced with a 3D perlin noise along vertex normals. Increase fog on planet proximity to emulate atmosphere (if any).

    That's what I'm using here

    I recommend checking out some videos about how they do it in KSP. Most of the second half of this talk is about planet generation.

    After some digging and examples, I want to try the method where you map a cube to a sphere..
    Does anyone know how this can be done??

    Ok i got the cube mapped to a sphere and it is subdivided...
    Another question, how can i implement noise to only generate on top of the mesh and not reshape the entire mesh?
