[osg-users] Camera Placement Question: Geocentric reference
Hi all, I'm having difficulty moving a camera to a specific point to look at in a geocentric coordinate reference frame. I've got a geocentric point that I want my camera to look at and the point is in x,y,z form where x,y,z are in meters. I do not understand how to translate and rotate my camera to this point. Is there a setByViewMatrix method in OSG any more? Some examples refer to it and I can't find it. If not, is there an equivalent? Or is there an easier way all the way around? Thanks for the help!
