Vizard can then render models and combine them with video captured from the webcam.  Vizard uses the position and orientation of the markers for placing these models in the AR scene.  The video tutorial in this article shows a short demo of this in action and then steps through the basic code for tracking a marker and linking a model to it.]]></description>
