Hi Oliver, Juan provides an example of how to do it, but doesn't specifically say how it works - the key is creating a pbuffer graphics context to assign to the viewer so it can use this for render. A pbuffer is an off screen Pixel Buffer that can be used in place of a conventional on screen window.
