Hi Wally,
have a look at the code path of the example:
osgprerender --image cow.osg
It already has a spinning cow and copies the image back in the callback.
What you have to add is just the image write e.g.
osgDB::writeImageFile(*myIm, "im.jpg");
and maybe some manual stepping.
If you feel more adventurous, have a look at the osgscreencapture example.

I am interested in creating a small OSG programs that will read in a model of
whatever type and then render screen captures that would mimic a 360 rotation
around the model. I would imagine this would be rather simple to write but my
days of writing C++ are rusty at best and my initial attempts have proved to be
fruitless (got a bunch of gray screen captures).
The basic idea is that I could run a command line program with one argument
(the path to the model) and have that do the stepping, say 36 steps of 10
degrees each, taking a screen capture at each step and outputting the sequence
to JPG or PNG (i.e. model01.png, model02.png, ...).
Are there any kind souls out there that could help me with such a task or know
of something that already may do such a thing?
Thanks in advance for your help,
Wally Atkins
