Re: [osg-users] OSGViewer camera position and external data
the png plugin is based on 3rd party libs. If you have used CMAKE make sure the path for the 3rd party libs is correct. To me it looks like the png plugin has not being compiled Nick http://www.linkedin.com/in/tnikolov On Fri, Aug 28, 2009 at 2:26 AM, Alex Malhao franciskovi...@gmail.comwrote: Yes, you were right, there was a part missing, my mistake.

Which values should go inside brackets of setHomePosition(...) ? Any example? -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=16803#16803 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

I won't answer as it's clearly time you learned how to read the headers... as it's pretty clear what the values should be from the naming the parameters.

Re: [osg-users] OSGViewer camera position and external data
I suppose that: Code: osg::Vec3 LookFrom, LookAt, Up; LookFrom = osg::Vec3(10,0,1); LookAt = osg::Vec3(10,0,1); Up = osg::Vec3(0,0,1); viewer.setHomePosition( LookFrom, LookAt, Up ); viewer.home(); will do the job.

[osg-users] OSGViewer camera position and external data
Hi, When I load a map with OSGViewer the camera is positioned very far from the map. How can I change the initial position of the camera? There is one other question, how can I use external data (gamepad, wiimote, etc..) to make movements inside my osgViewer? Thank you!

Either write your own CameraManipulator an attach that to the viewer, or dispense with a CameraManipulator and set the viewer Camera's view matrix manually on each new frame.
