Have you looked at any of the examples? Lots of them collate different models together in different ways. Try osganimate. Also practicing your source code search skills as it's invaluable for answer many questioning. Try searching the example directory for the keyword readNodeFile and then look at the examples that have readNodeFile multiple times. > 2.

This is pretty open ended. What do you mean by different coordinates? Different coordinate systems? Different scales? Are they imported from different tools and should overlap? Should they sit side by side? > 3. how to transform the coordinates form one stly to another? > may be the three questions talke the same thing,do you understand me? i I can understand your english fine, but... there isn't really enough specific information to know what the problem you are trying to tackle as it's too open ended, what solution to choose depends on the actual problem you have in hand, without knowing this one can't give a specific answer. The best guess I can give is look at osg::MatrixTransform, but I really couldn't say if this is appropriate to your problem.
