First off, damn, chipmunk is cool, thanks for your work on it! Now, I'm a longtime rubyist playing around with rubygame/gosu over the last year.
Recently I started on a small "moonlander"-game in Gosu/chipmunk to learn more.
I made the the planetsurface a big polygon (painted in / imported from inkscape) but soon bumped into the "cant have pointy polygons" limit.
Now i ponder over how to continue. I guess I could paint the surface as alot of convex polygons..
Skimming through the C-documentation / forum there's talk about "lines", maybe this what I should construct my planet-surface from?
I cant find anything about lines in the rdocs though so either it's not supported in the rubybindings yet (if not, is this planned ..hm, during 2008 or simular
?) or the it's just missing from the docs?
