I used a 64x64x64 3D cellular noise texture to cover a sphere, but the resolution was too low.

Since the texture was tileable, I noticed that there was no downside to tiling it like in 2D because you don't notice repeating patterns with a curved slice of 3D space.

Is there a way to warp space to avoid visible tiling, even when you aren't cutting the texture with a curved shape?

This could be the key permitting 3D noise in the moon and clouds attempt from #263, since 3D noise textures can't be very wide/tall when they have to support an extra dimension.

Here's your belated screenshot.
