Send me the code if you want. I will take a look. If the size of data would be larger, use my email address only.

Re: [osg-users] different behavior on the trackball manipulator
Hi Nick, there are two major changes to CameraManipulator::computeHomePosition(): - the computation uses bounding box by default (the model center is located more precisely) - the computation considers the camera fov to make sure that the model nicely fits to the screen (small fov may make the model larger than screen while big fov too small). If there is a bug, you see some problems with the approach, or you would like some adjustments, we can discuss them further.

Re: [osg-users] different behavior on the trackball manipulator
Hi JP, the zoom update submission was sent to Robert and it waits for commit. It reverts the zoom to use original behaviour by default. Concerning 4 manipulator, which one do you mean? I am expecting it is TerrainManipulator. It avoids you to go over +/- 90 degrees in vertical direction. It can be turned off by setVerticalAxisFixed(). Just for the case that you would think that the behaviour should be different, we can discuss ideas. John J.P.

The 4 manipulator now does a funny flip for the southern hemisphere. And I think, will confirm, that the zoom works differently. jp -Nick ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] different behavior on the trackball manipulator
Strange. Unfortunately, all my models gets centered on the screen, so I can not reproduce the problem on my side. Can you investigate further what is happening and whether the problem is not in your code? Is the problem happening with osgviewer as well?
