Generate [OpenSCAD](https://openscad.org/) 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

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.
