Hi Bo, The OSG rendering traversal will set the projection and view matrices itself during each new frame so you'll need to get the projection,modelview and viewport settings from Maya/OpenGL and then assign these to the OSG to keep everything in sync. As Rui mentioned the osgviewerGLUT example will illustrate a barebones way to integrate the OSG, us the osgViewer::GraphicsWindowEmbedded functionality, also see the osgviewerSDL example as well as it does something similar.
