[osg-users] camera node in osg file

[Robert Osfield]

Hi Erik,

What do you mean by a camera in the scene graph in this context?  Are
you looking to control the camera view and animation path?  Or do you
require to control the capturing of images via an active camera such
as a RTT effect?

Robert.
