One particular usage of the SoOffscreenRenderer is to make it render frames to be used for the construction of movies. The general technique for doing this is to iterate over the following actions:

  * move camera to correct position for frame
  * update the |realTime| global field (see explanation below)
  * invoke the SoOffscreenRenderer
  * dump rendered scene to file

..then you use some external tool or library to construct the movie file, for instance in MPEG format, from the set of files dumped to disk from the iterative process above.

It is not even necessary to use an external tool.  The FFMpeg wrapping

allows you to generate movies from within Octave.


Ok, this feature is included in Coin3D, which is the c++ opengl library I am using.

Thanks for the link, Stefan.
