This is interresting; the code with json is available ; is there a way to use json code with grasshopper?

JSON (i.e. JavaScript Object Notation) is not a programming language, but a (really nice) language-independent, human readable, key/value based file format. You can use the standard Python json module in GHPython to read/write these. I believe P5 is the JavaScript flavour of Processing. As there is no JavaScript interpreter in Grasshopper (that I know of), your best bet is probably to implement the code in e.g. GHPython or C#.

Could it help ?

Epicycles, complex Fourier series and Homer Simpson's orbit

Hello here is a good script to replicate that, without the circles at the moment. I made a big mistake with complex multiplication. Here I use complex which are embedded in Grasshopper. [image] Epicycles, complex Fourierv 2.gh (13.0 KB) And here an implementation to blend between 2 shapes, that is very simple to do with this method as each curve is represented by a set of coefficients. [Frame_] Like in this tweet Epicycles, complex Fourier.gh (30.8 KB) An animation with 100 points [F…

That’s nice i will try it ; looks like it is the solution
