Video flowfield in Flash

I ported my earlier OpenFrameworks experiments, where I moved particles based on video input, to ActionScript, and here is the result.

Click on it to change the video. If it doesn’t run well on your computer, press the – key to reduce the number of particles.

I love OpenFrameworks

Smoke! from Ralph Kok on Vimeo.

This is an effect done in OpenFrameworks, which is similar to my last video, but uses the webcam in a more visible way.

Lots of particles reacting to webcam input, on top of a blur. It’s so simple

Lightning in OpenFrameworks

Yesterday, I ported my AS3 lightning renderer to OpenFrameworks with the help of Rick Companje and Joris Rotteveel.

Edit: download the source at the OpenFrameworks forum

My most recent iris rendering:

An iris is a beautiful thing

For a while now I have wanted to render out an iris in code alone, so I have now finally started experimenting in that direction.

I must say I am not unhappy with the results sofar, especially since I have stumbled onto some nice byproducts along the way

I love particles

This little diddy was inspired by Ralph Hauert’s beautiful Bloom animation.

Try moving your mouse and clicking every once in a while

L-systems revisited

admin — Mon, 16 Nov 2009 17:10:13 +0000

I sat down again to update my ActionScript L-system renderer so that it can use multiple rules and new characters.

Next, I fiddled around a bit with axioms, rules and angles and came up with some pretty cool new curves (if I may say so myself). Check them out below.
I’ve also added the renderer application, if you run it you can play around with the curves (controls are listed at the bottom of the app). If it is too slow, please decrease the number of iterations or resize the window to be smaller.

(Please open the article to see the flash file or player.)

ShameStation’s Bright future

admin — Sat, 08 Dec 2007 10:43:25 +0000

In the last weekend of November, we attended the STRP festival with the ShameStation. That was a lot of fun and we were pretty popular, with curious people coming to see what this ‘game’ was. During these four days of fun we were also spotted by Bright, who immediately wanted us on the BrightLive festival. It seems that the star of the ShameStation is on the rise

Here’s two videos showing the ShameStation in action on STRP festival:
