The attached image shows a very simply plate with a hole in the center. This is a simple stl file with no contour data. The stl file is also attached. The resulting shading appears to be messed up. Any thoughts on why this is and how to fix it? Also, I am working with the example ios application. How do you change the background color? I changed the background color of the GLView in MainWindow.xib and that did not work.<br clear="all">
