I love OpenFrameworks :D

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

An iris is a beautiful thing

December 19th, 2009 admin No comments

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 :)

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

November 16th, 2009 admin 1 comment

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.

Placebo Interactive Video

August 28th, 2009 admin 2 comments

Placebo has released a new single called “The Never-Ending Why”, which is accompanied by a fantastic music video, created by Champagne Valentine.

We at Random were asked to help in the creation of an interactive video to go alongside the linear video.

After a lot of hard work, the result turned out, if we may say so ourselves, amazingly cool!

Check out the linear video here, and try the interactive here.
