To the users: sorry I was out of the office for the duration of the holidays 
and did not see this response. Also, in this example, the camera needs to move 
forward a bit before the cacti become visible.

Alberto,
I am not getting the CameraGroup::frame() error you speak of... the only error 
I get is if optimizer is set to true and the user hits Esc it causes a memory 
violation, again part of the problem I'm having.

Hi, I don't even know what your problem is. I just compiled the code and run it 
and I got:

CameraGroup::frame() : Please call realize() first

Are you getting the same?

Regards,
