Can I do this in Ruby? Basically, I want to copy this guy: I don’t even know what words I’m supposed to describe this. ---

Can’t specifically think of any ruby libraries or bindings that would help with this, but the basic plan of attack would seem to be: 1. Design your object in a 3D modeller or CAD program 2. Export it to some standard vector format 3. Find a library that can work with that vector format and calculate cross sections Your 3D modelling program might actually be able to do the cross sections itself, and generate them in a loop via its internal scripting language. martin
