Re: [osg-users] camera postion problem
Hi Wiebe, would you please tell me how you got NodeTrackerManipulator to work? I do not seem to be setting it up correctly and it is not working for me. Thanks!

Re: [osg-users] camera postion problem
Hi Thanks for the help, I found the problem this morning. There where some matrices mixed up.
