Dear Performers,

For an Augmented Relality application, we need to put an RGB image (720x576) at
the background of the Performer window (Channel). There is a possibility to
achive this with OpenGL and IRISGL function calls (glRasterPos3i, glDrawPixels)
, or mapping the image on a far texture plane. However these solutions are more
or less heuristic, and adding complexity to virtual camera calibration, and
preventing us from using different image sizes easily.

We are looking for a set of Performer functions to draw an image on the
background. < the best would be something like:
              pfLoadBackground(pfChan, rgbimage) ??!!! >

Is this possible and how ?

Kind Regards

Selim Balcisoy
