Automation of 3D Paper Modeling
i am a programmer and not a mathematician, and my math knowledge are a little bit rusty. i have found this nice picture surfing on the net:
and i want to replicate it.
as i remember there is written an implicit function, and for plotting i need to transform it in a parametric one. is this right? how can i do?
then, once i have the parametric surface i can iterate over an axis and obtain the slices for replicate this nice paper-work.
i am code agnostic and i can use every opensource tool for mathematical computation (octave/matlab, wolfram alpha, python, java/c/etc).
