Surface-Oriented CAD, Math, & Telescopes

July 16, 2011

surfcad is a python proof-of-concept CAD library I’ve been writing for what I call “surface-oriented CAD”.

The idea came to me when I realized that some of things I’d been trying to make in openscad, a CSG based CAD program, would have been much easier to do in the software I’d written for making models of mathematical objects (eg. this model of a solution the diffusion equation). In this software, surface were constructed based on mathematical functions. One had to think to make sure that their object was closed, but it was possible to describe things that would have been prohibitively difficult in a CAD program like openscad. (more…)
