Processing Month, Day 9 - Circular Pixels

09 May 2011

Today, we’ll take a look at how we can work with images in Processing, and how we can use color values of individual pixels to create an interesting result. First thing we need to do is finding an image to use and resize it so it has the same dimensions of our sketch.

Processing Month, Day 8 - Animating Bubbles

08 May 2011

To animate the bubbles we made yesterday, we’ll need to add a new method to our Bubble class: the update() method. If we call this method before we call the render() method on our bubble objects inside draw(), the y-position of the bubble will change, and the bubble will be rendered on a new coordinate. The update method looks like this.

Processing Month, Day 7 - Bubbles

07 May 2011

Functions are great to draw multiple objects to the screen at once, but if you want to control each of those objects and animate them, you’ll need something more powerful. Today, we’ll venture into the world of OOP: Object-Oriented Programming.

Processing Month, Day 6 - Square Flowers, Part 2

06 May 2011

Processing Month, Day 3 - Triangle Grids

03 May 2011

Day three will be all about triangles. But we’re not going to use the triangle() function. We will draw points and lines again just like the examples from day one and two, but we will restrict the lines so they can only be drawn on a grid based on regular triangles. To make it a little more interesting, we’ll also add animation.

Processing Month, Day 2 - Connecting Points, Part 2

02 May 2011

Today’s sketch will be similar to the one from yesterday, only we’ll use random points and connect them in a different way. We will draw a line if the distance between the points is less than a certain number. The distance will also be used as the value for the transparency of the line. Points close to each other will have a less transparent connection between them, points that are further away will be connected by a very transparent line.

Processing Month, Day 1 - Connecting Points, Part 1

01 May 2011

In this first article, we’ll take a look at how we can calculate points on the circumference of a circle and how we can connect them. We need to do this in a flexible way so we can draw images based on 6 points as wel as images based on 18 points.
