Simon was preoccupied with vector functions for most of the day on Saturday, compiling what, at first site, looked like a monstrously excessive code in Processing (he recycled some of it from the Processing forum, wrote some it himself and translated the rest from Codea). Originally, he was gong to use the code to expand the 3D vector animation he made into a roller-coaster project he saw on Codea and wanted to create in Processing, but got stuck with the colors. What happened next was fascinating. In the evening I all of a sudden saw Simon write in a new online editor Repl.it – he was translating the vector code into… Python! He hadn’t used Python for quite a while. I don’t know what triggered it, maybe Daniel Shiffman noting last night during the live stream session that “normal people use Python for machine learning”. Simon also said he had sone some reading about Python at Python for Beginners and Tree House!
He isn’t done with his project in Python yet, but here is the link to it online: https://repl.it/JAeQ/13
Here Simon explains what he is writing in Python:
Simon did the 2D, 3D and 4D classes but eventually got stuck with the matrix class in Python. He then opened his old Xamarin IDE and wrote the 2D, the 3D and the 4D classes in C#. In the video below he briefly shows his C# sketch and talks about Cross Product in general:
And this is a video he recorded about vector functions (in Processing, Java) the day before:
