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
class at
http://www.dsp.sun.ac.za/~stefan
allows you to generate movies from within Octave.
