When it didn't work, I spent more time porting the OF blob tracking extension to OF.06, and it still didn't work. But today I found a rather silly workaround.</p> <p>1. Connect the webcam you want to use</p> <p>2. Open skype, go to preferences and turn on the video so it shows the iSight image.</p> <p>3. Forget about the skype preferences window but don't close it.</p> <p>4. Start the OF app, stand-alone or from the Processing app.</p> <p>5. The OF app should get image feed from the external webcam.</p> <p>Ok, so now I'll be able to focus more on the interaction (“Playing with new mac”)</p> rocaa@student.chalmers.se (unknown) Thu, 09 Apr 2009 00:45:00 -0700 http://idp.mexinetica.com/blog/blog/blog/view/56/setting-up-the-of-code-in-gnu-linux-a-mac-osx http://idp.mexinetica.com/blog/blog/blog/view/56/setting-up-the-of-code-in-gnu-linux-a-mac-osx <p>0.
