Craters

Another quick update. I have been working on adding craters to the procedural moon. I implemented a Voronoi diagram shader in HLSL and then I tweak it with quite a few different parameters to generate conical pits that are distorted slightly with fBm noise.









I tried for quite a while to get rims around the edges of the craters, but I couldn't get it to work. I tried using a colormap to alter the Voronoi results, but I was having issues with the it. I will continue to tinker around with it because I think having rims would add quite a bit.

Interesting fact: If I add even more fBm noise to the crater distortions, it forms pretty cool canyons:

That's No Moon ...

Quick update. First, I switched to more "moon-like" textures.



Then, I tweaked some of the parameters to my existing noise function.



Finally, I started messing around with sums of two different noises.



Here's a detail shot showing the "better" noise at the surface.



There's a lot more work to do!
