A parametric object.
‘Twirl’ is a parametric object that I made for a computer class. It is made out of laser cut cardboard.
How was it programmed?
Rhino & Grasshopper
I wrote a script in Grasshopper (a parametric plugin for Rhino) which layers a shape, places the outlines of those layers on a flat surface and puts numbers on them. You can take these lines, laser cut them and engrave the numbers.
