Particle based animation with openFrameworks

Continuing on with my other particle based generative art, here’s an animation I made with openFrameworks.

Particle based generative art with openFrameworks

I’ve recently started playing with openFrameworks and I have to say I’m very impressed. Having messed with Processing previously, openFrameworks doesn’t feel too alien. It does have a steeper learning curve than Processing but it you’ve programmed C++ before it shouldn’t be long until you can whip up your first masterpieces.

Last week I’ve created a very simple particle system and had each particle leave a trace as it was animated. The following images are variations on the same theme. They are pretty much the same program with a few changes made between each run.

The common thing in all of these is that the particle movement is governed by Perlin noise.

Calibrator: An Arduino library to calibrate sensors hooked to analog inputs

Once you get past your first few projects with the Arduino, you soon realize that the calibration method they show on their webpage is just a sample and cannot be used with many sensors without polluting your code with a ton of variables.

So, here it is. My own take on sensor calibration library. You can download the source code and a more detailed explanation on the github Calibrator page.

This is how you use it:
