Hi Yong, You'll need to load the file then use a custom NodeVisitor to traverse through the scene graph to locate all the osg::Geode leaves, then look at all the osg::Geometry within the Geode's and get the colours from the ColorArray attached to the osg::Geometry. Have a look at the NodeVisitor implementations in the OSG to see how they work. Also look at the examples and published books.
