Simon comparing possibilities to create 4D noise in different computer languages:
Simon built a program in Codea visualizing the absolute value of a vector:
A set of awesome Codea tutorials that Simon recorded for those who are just starting to program in Codea. Simon ported examples from Processing (java) into Codea (Lua):
In the second tutorial (in two parts), Simon explains how to write a physics simulation program in Codea using forces like gravity, friction and spring force. Anyone watching will get to use some trigonometry and see what arc-tangent is for! The original code in Java comes from Keith Peters (Processing).
Here are some notes from when Simon was explaining the arc-tangent to me the other day:
Simon translating the game of Pong from Codea (Lua) into Processing (Java).
On Monday this week Simon spent hours converting hexadecimals into RGBA values for the 140 colors supported by all modern browsers and creating a color file in Codea. He used the w3schools color map available at https://www.w3schools.com/colors/colors_groups.asp and an html color codes converter http://html-color-codes.info/
Some of the color names were quite exotic (like Chartreuse or Bisque ), and we looked those up together in the dictionary. We also took a very close look at the relation between red, green and blue values and found out that red was added every time to make colors lighter, even in shades where you would not expect any red.
Simon later made a nice design pattern in Codea using the color file:
Simon translated Daniel Shiffman’s Diffusion-limited Aggregation Coding Challenge into Codea. The coding challenge explores the generative algorithm “Diffusion-Limited Aggregation”, whose visual pattern is generated from random walkers clustering around a seed (or set of seed) point(s).
Unfortunately, every time the iPad falls asleep the application seems to stop, so we never got a sizable tree.
Some more translations, this time from Codea (Lua) into Processing (Java).
Physics Lab tests from Codea:
For my birthday, Simon made me some Fireworks:
He made them look even better the following day, by adding trails:
We’ve also thoroughly enjoyed our birthday weekend at Brugge and especially Knokke. Fine to discover such fabulous beaches in the neighborhood. Simon loves water. Perhaps, because it is somehow related to the fluidity and of his mind and because of the freedom water provides to his body.
