This is my lego planet. It's made entirely of clear 4x2 Lego blocks.
It was to have a diameter of 500 units, but anything much over 20 and it
crashes my system.
Here's the source.

Yep, those exponentially huge scenes will do it every time... Something
tells me you will never see your planet rendered at 500 units!

I gave the scene a try and then put another zero onto the 20 units. This
800MHz CPU struggled with it for 8 minutes before the memory gave out. Has
taken another 14 minutes to free it back, at least much faster than my other
computer with 256MB and 500MHz CPU would have been. I have 192MB on here.
I was going to ask if coincident surfaces might be the cause but now I
wonder. Still, I'm not certain about it but even with merge wouldn't so
many coincident surfaces within a clear CSG be potential trouble?

I was thinking that instead of making it solid, I could make it, say 5 units
thick... That's still a lot of legos, but maybe I could get a bigger sphere.

That's just what I was about to suggest! Probably even 3-4 levels thick
would be sufficient. (While leaving the center hollow.) All those cylinders
would obscure any objects that were more than a few levels deep inside the
object anyway. That way you should be able to make it pretty big.

This is interesting: I put in some #render commands, and I found that my
#declare C=C+BZ;
line NEVER gets called.
Did I screw up the #if command?
