Generate OpenSCAD files for visualizations of arbitrary functions.

WHY?!

Why not?

I wanted to be able to generate 3D models of various mathematical functions after seeing this Tweet by \@nwilliams030

How?

This is one simple Ruby script. At the top are the only things you need to edit:

  • t: the starting input value for your function (f(0))
  • step: the stepping between function values
  • tmax: the end value
  • calc(t): your function, expected to return an array with (x,y,z)

The main loop iterates from t to tmax at step increments, calculates the function calc at each step, and draws cylinders between the points, with a sphere at each point (for a smoother appearance).

After setting it all up, run the script, sending the output to a target file. Open in OpenSCAD, render, voilà.
