Introduction to openFrameworks

12 January 2010

I’ve been playing around with openFrameworks for a while and I decided to write some articles about it. Coding in openFrameworks feels a lot like working with Processing so it might be easy to convert some of my old Processing sketches to openFrameworks. In this first article I’m going to compare some of the functions of openFrameworks to those of Processing to show you how easy it is to move from one platform to the other.

Managing Inspiration

26 August 2009

Every day I spend some time reading RSS-feeds. I read a lot on design, technology, usability, … Just about anything I’m interested in as a designer. The best articles end up on Delicious for future reference. I also see a lot of inspiring images. Most of these images come from places like ffffound, but does it float, The Dieline and some other design blogs. The images I like end up in my inspiration folder on my computer. So far I have about 4000 of them. I’m using one of the standard Apple Screen Savers to start showing the images at random when I’m away from my computer.

OpenGL ES for iPhone: Drawing a Circle - Part III

27 May 2009

In part 3 we’re going to take a look on how we can optimize the code to make our app run smoother. At this moment, all vertices of the circle are calculated each time the view gets drawn.

I’ve learned a lot by reading Beginning iPhone Development by Dave Mark and Jeff Lamarche and the iPhone Development blog. In these articles I want to share some of the things I’ve learned. Read this article as an introduction to Generative Design on the iPhone. So let’s do some OpenGL programming.
