Simon continued his lectures about transformations in Processing (Java). Processing has built-in functions that make it easy for you to have objects in a sketch move, spin, and grow or shrink: … Continue reading 2D and 3D Transformations in Processing (Java) Continued
The earthquake data visualization coding challenge by Daniel Shiffman went further than just a 2D map – it went 3D! Simon managed to complete the challenge, except for the very last … Continue reading 3D Earthquake Data Visualization Coding Challenge
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
On Saturday Simon was mainly busy with the Inverse Kinematics Coding Challenge: Simon watched two out of Daniel Shiffman’s four kinematics videos and studied forward inverse kinematics in Processing (Java) to create a … Continue reading Inverse Kinematics in Processing (Java)
On Friday Simon finished another beautiful Daniel Shiffman coding challenge called Mapping Earthquake Data. The purpose of this coding challenge was to visualize earthquake data from the USGS website (http://earthquake.usgs.gov/data/) by mapping … Continue reading Mapping Earthquake Data Coding Challenge
In the two videos below Simon is talking about 2D transformations in Processing. Transformation functions in Processing (Java) make it easy to have objects in a sketch move, spin, and grow … Continue reading 2D Transformations in Processing (Java)
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
The next step after the Spherical Geometry Coding Challenge was to turn the sphere into supershapes using Daniel Shiffman’s “superformula” in Processing (Java). The result resembled the supershapes Simon had programmed … Continue reading Supershapes
Simon completed the Spherical Geometry Coding Challenge by Daniel Shiffman! In this challenge, he created a sphere in Processing (Java) using spherical coordinates and triangle strips. Simon had already tried doing this … Continue reading Spherical Geometry Coding Challenge
Simon built this awesome animation that looks and moves like a hammock on Sunday, a coding challenge on Daniel Shiffman’s channel. In this challenge Simon used the toxiclibs physics library to create … Continue reading 2D and 3D Cloth with ToxicLibs
Simon got seriously hooked on Matter.js, a a 2D JavaScript physics library that supports rigid body collisions and constraints. He started with Daniel Shiffman intro to Matter.js, downloaded it using GitBash … Continue reading Matter.js (Physics Library)
Simon spent his Sunday morning programming SVG (scalable vector graphics, a file format for static and dynamic vector images in XML) elements. The code (from w3schools) largely relies on coordinates, … Continue reading SVG shapes
