Attempting to get a decent cratered planet.

Here I try this technique from Johannes Dahlstrom. Looks ok but there are a few problems with how craters overlap, including a particularly nasty example near the terminator. Hopefully going to be able to try a few other techniques soon.

Also served as a practice for multi-core rendering with POV-Ray, this is something new for me.

Thats really really good. I know a great way you do craters and asteroids in Bryce to make a crater texture turn the view so you look straight down on the plane and make sure nothing casts any shadows make your craters resize them duplicate them and then when you are happy apply a texture to it. For asteroids Bryce is the easiest way to make them make a lot of stones and don't duplicate make them all seperate stones make sure they all have the same texture render them and when you have rendered them go to render options and choose object mask then render that as asteroid.msk open them in photoshop cut out the msk image paste it onto the asteroid image and then either cut them out and place in your image or define them as a pattern. Bryce is capable of many things some consider to be impossible.

I am sure you probably know all of this though you are very good at your work(I just wanted to share).

Regards

Karl

Yes, that one crater pair near the upper end of the terminator does look a little strange!  But that could be fixed with a little erasing, and the rest of the planet looks very good indeed.  I like the way some of the craters look older and more eroded than others.

That is very well done. Makes me wish Blender had that ability.

Thanks!

I'm experimenting with making it into a mesh instead of using an isosurface, trade-off between parse time and render time. I was initially hesitant about the idea of manual edits, but rendering to a heightfield will also allow manual edits while still letting me animate it if I want.
