procedural craters

Hi!

Here the craters on a moon data .img file. In the left upper corner is only the IMG, next the IMG with colours and finally the IMG with fractal details and procedural craters.

Thats looks really good!

Indeed. It looks a bit like craters aren't really half domes, but have a flattish bottom.

The craters are adjusted to fit the NASA photo from the moon. Some are deeper and some are not. It took me quite some time to figure out what looks best. To get small round craters in a triangle landscape I needed a detail from 2 and Aa 8.

I think it's quite logical for the craters to have all different shapes, as some will be filled with debris from other impacts, other craters will be very deep, being from a faster impact, other a bit angled perhaps. So if working with procedural craters a bit of variation is good.

At first all procedural craters had the same depth but different sizes, and it looked as if the surface was hit by a meteor shower only yesterday and not as if it was of ancient age. So I did the adjustment for the 20 different procedural craters.

Here is a new render from the pole region of the earth moon with the NASA data and the procedural craters with some fractal detail.

So now I need a spacecraft ...

They are there, on the net...
