From Michael Hartman, " Here is the MFC_OSG example. It is very basic and the community is welcome to enhance/improve this example. There is one bug documented in the Readme.txt file that I just have not had time to solve. Also, the code is built outside of the OSG environment and uses environment variables to get to the OSG distribution headers and examples. That should be the only change a user needs to make to get the code to compile."
