hmm.. sure would it be possible. I'd guess you want a random function
that returns the same list of values for every recompile and is
configureable using a seed value, right? I've added that to the todo list.

Thanks! No hurry.

tghis is what happens already now. the bigger of the two radii of the
cylinder defines the number of facets.

When I use something like:
    cylinder(h = 10, r=25);
I always get 32 facets. No matter what radius I use.
It seems to stop after r=10 ...
What do I do wrong?
Or is this by design?
I sometimes only need part of the curve and then the resolutions is a bit low at 32 facets for the whole shape.

I actually am pretty happy with a simple traditional mailing list..

OK with me. As long as you are happy :-)

I think the documentation is the piece where the most help is needed atm.
examples with pictures would be a great improvement. Zach added pictures
for some of the primitives - but I'm sure there is still much room for
improvements..

I'll do that!

Thanks, Trumpetto

the sections about Special variables should answer this question:
