It depends on the level of control you need with positioning objects and any dynamic geometry.
One way would be to put each object under it's own MatrixTransform and add an update callback that positions/orients the object from time history data known by the callback. You could also use osg::AnimationPath and osg::AnimationPathCallback to do the same thing at a higher level. See the osganimate example. The first solution provides the most flexibility, but requires the most code, you code everything you want it to do. The second solution requires less code, but it constrains you to the capabilities provided by the osg animation classes.

I am trying to animate an assembly of a pulley using callbacks. My osg experience only goes as far as the nps tutorials and am not sure how to reference the parts of the assembly in the callback. I am not using DOF transform or searching for nodes. I am just trying to manipulate three parts that are defined as individual nodes. Any advice anyone has would be a great help thanks, Chris _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- This is a PRIVATE message.
