Arrays
Arrays are used to store data, but unlike the other data storage types we have been using (such as variables) arrays have the ability to store more than just a single value. Arrays can store multiple values of the same datatype in much the same way that an ordinary list (such as a grocery list)…

Why use Object-Oriented Programming
One of the fundamental concepts that makes OOP (Object-Oriented Programming) so popular is known as data encapsulation. We have already discussed how a variable can have a greater or lesser scope depending on where it is declared, that is to say that when a variable is not declared within the global variable scope it can…

The Blueprint Analogy
By creating classes we categorize the data we are representing and give these representations a context by associating them with features in the programming languages API. However a class is never used in the main program, it must first be instantiated as an object and the object is what we would use in our main…

Object-Oriented Programming
Object Oriented Programming Object Oriented Programming is a modern day programming paradigm, meaning that it is a fundamental style that suits the task of creating modern software. Most popular modern programming languages support OOP (Object Oriented Programming), and as a result understanding the fundamental concepts that define it within Processing can help in implementing it,…

More Random Circles
This example builds on the random circle exercise by constraining the random colour aspect of the sketch and only draws circles not ellipses. size(600,600); smooth(); int circleNum = 50; noStroke(); for (int i = 0; i<= circleNum; i += 1) { fill(random(200, 255), random(100,200), random(100,200), random(100,255)); float randomDiam = random(width); ellipse(random(width), random(height), randomDiam, randomDiam); }…

Inspiration I
The Artvertiser – Julian Oliver, Damian Stewart, et al (video) The Artvertiser is a software platform for replacing billboard advertisements with art in real-time. It works by teaching computers to ‘recognise’ individual advertisements so they can be easily replaced with alternative content, like images and video. Newstweek – Julian Oliver (video) Security experts discover a…

Randomness
It’s arguable that all generative art includes some degree of randomness: without randomness, there can be no unpredictability. Almost all programming languages include a function equivalent to Processing’s random function, but returning a truly random number is an impossibility for a predictable machine. Computer-generated randomness is always pseudo-random, using mathematical formulae, often including a reference to…

Datatyping
You might have noticed something else that’s new about the active mode structure of a sketch, that being the usage of the void keyword preceding both the setup() and draw() functions. The keyword void is used for defining functions that do not return a value, all other user defined functions must return a value of…
