I want to render a QC comp once, display the result full screen on the main display and a cropped portion of the result

From what I understand I will have to create use one QCRenderer and then use lower level OpenGL contexts in order to
crop a section and send it to the second display.

Yes, to do that efficiently, you would need to render the composition in a pBuffer using a QCRenderer, then create an OpenGL texture from that and display it the way you want on each screen.

Except from reading another post, it seems that the QCRenderer does not have the possibility to be bound to Interface builder controls or to be passed keyboard and mouse events like a QCView does? I'm just double checking because I was not 100 percent sure what "KVO compliant" meant from the earlier post.

So at the moment the only possible way of running a composition full screen with mouse and keyboard control

is directly within the Quartz Composer application with the full screen option? is this right?

thanks

Roger
