have included this Multiple Document Interface example here because any game development requires a good editor for constructing the world or models. The editor should provide multiple views of the scene and therefore the most intuitive method is to use multiple windows that allow perspective and orthographic views. In my search of the internet I was unable to find any example code that showed how to program an OpenGL Multiple Document Interface application using just straight Win32 programming with no MFC so I decided to program it myself. This MDI example only shows the same scene in each child window but should be easily understandable and modifiable by anyone familiar with programming a standard MDI application using the Win32 API. I will follow up this example with a more complete editor example.
