Simon followed Daniel Shiffman’s Fractal Recursion tutorial on how to write functions in Processing that call themselves (recursion) for the purpose of drawing fractals. Later he programmed a Sierpinski triangle from memory, … Continue reading Recursive Function: Sierpinski triangle
Simon built another project of his own design. His program allows to draw intricate patterns that resemble Islamic tiling, the building block being a polygon of your choice. First, you … Continue reading Connections Project in Java (Simon’s own code)
Simon made this beautiful interactive Islamic star pattern from Daniel Shiffman’s one hour long coding challenge he devoted to the refugees. The coding challenge is based on this paper about … Continue reading Islamic Star Pattern
Since Simon has been using so much trigonometry in his programming lately, we decided to review some SOH-CAH-TOA during his regular math classes and did some Brilliant.org quizzes: Simon also enjoyed … Continue reading Math > Back to Brilliant.org to train Trigonometry
Simon showed me 3D trigonometrical functions (like tan(x) or cos(x*y*9^10) in his Solve calculator app and we were surprised at their incredible resemblance with forests and flower fields. I mean, is there anyone … Continue reading Forests and Flower Fields
We spent yesterday under the beautiful fractal tree branches of all sorts. Simon followed a whole set of coding challenges by Daniel Shiffman in algorithmic botany featuring several ways of … Continue reading Fractal Trees 2.0
We have purchased something Simon wanted to have for months already: new software to construct the craziest 3D-supershapes! The software is pretty old, developed by Australian programmer Paul Bourke long before … Continue reading Crazy Supershapes
A superellipse This was the formula (Simon doesn’t fully understand it yet but loves playing with it):
Inspired by the formulas used by Daniel Shiffman to draw phyllotactic patterns, Simon decided to get back to his old favourite. In this rather long video Simon tries to use … Continue reading
Thursday night Simon told me he really needed to draw “something about a circle”. We were having an evening walk at the local park so I gave him a stick … Continue reading The Supershape Formula
Simon came up with this “golden infinity” concept on Monday evening and had to wait until Tuesday morning to draw it for me. He started out with an equilateral triangle … Continue reading Golden Infinity
Is that a bunny on the first picture? No, says Simon, it’s the area of a quarter of a cone! And that funny face on the floor? That’s the area … Continue reading 3D shapes dissected and unfolded
