Re: [osg-users] OSG RotateToPoint
Hi Dan, Unless you know Java3D RotateToPoint functionality I think it'll be hard to guess exactly what it does. I don't know Java3D so can't really help specifically, you'll need to explain more specially what you are after in non Java3D specific terms. Also worth mentioning is whether you are moving objects in the scene to a particular position in the world, or whether you are moving your main camera to that location. Robert.

I'm not entirely sure what you're trying to accomplish, but you might want to take a look at the makeLookAt method in osg::Matrix. If you're trying to rotate the plane to aim it at a particular point in space, that should do it for you. You can use the resulting osg::Matrix in an osg::MatrixTransform node. --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
