Re: [osg-users] current View Point

Each frame, you have to update your matrix. For the moment you set it, next you frame() the viewer, nothing more. Matrix will no update itself. To update it, do it in the viewer loop (after/before frame()), or create a new nodeCallback. Have a look on nodeCallback to see how to use it. Regards,
