    Good Job…I downloaded the FlarToolKit…made a custom marker and wrote over the flarlogo.pat with mine….. and nothing

    Do you need to install papervision or does everything come ready to go just by replacing the .pat with our own? with the FlarTookkit

    Great demo!!!!

    I have a question about the detector.getDirection() method. I want to detect if the marker is moving to left, right, up or down. This can be done?

    Thanks a lottt!!!
