ofVideoGrabber effect help


#1

Hi, I just started using OF not so long ago. I’m experimenting with webcam and ofVideoGrabber and I was wondering on how to achieve this kind of effect: https://vimeo.com/8218843 .

Any suggestion would be great!

hey, i think i already did something that you can use straight away, in my dotfrag addon:

in the example_test, in ofApp.h change ofx::dotfrag::Twist frag; to ofx::dotfrag::EchoTrace frag;, then compile and run the app, activate “hard cutoff” in the gui and set the gain to more than 1.0 and the threshold to less than 0.5, play with that

Awesome that’s perfect, thanks a lot!
