Edit: Updated image!

I have successfully sampled the surface of a sphere travailing along the 4th dimension through a smoothed noise field. It is currently very slow, and has a few tiny flaws, but it will be improved. Maybe I will make a 4D optimization on the N dimensional noise field.

My texture mixing code works too, so things will be getting interesting.

Details about the meaning of this will follow, but for now, just know that we are working on stuff.

That was fast.
I thought you were just learning about Perlin Noise fields a few hours ago :)

Ya. I finished the easy part, Time to implement my optimized n-dimensional interpolator. My head fails at n-dimensional visualization.

Contest: First person to describe how the cube texture at the left can get reorganized so it can make a smoothly textured cube wins! I added some solid colors to make it easier. Good luck!

First zoom-out so that your image is 1-pixel.
Then zoom-in until your image is 16x16 pixels…
Then make a cube!

Actually, I see how to solve your cube, but not without individually rotating each face :(
Edit: And replicating them.

ROFL!
This deserves a double-post!
I got it:

The squares were too small, so there were gaps between them. Fixed now.

Ice is now done. It works off of both latitude and elevation. After rendering the big one, I realized the edges on the land are too smooth, so I fixed it, and rendered the polar region of a new planet. Much better!

Is this all randomly-generated or generated from an arbitrary number?

Fully pseudo random. Repeatable, and editable. Also varies with time, but the current render speed is a bit low for animating. Currently it could do LOD, but does not have GUI for zooming.
