Three-Dimensional Modeling Under Windows

Hello,

While trying to work out how to do simple 3D graphics using software rendering (as opposed to handing all the fun stuff over to an API like OpenGL), I came across an old article that was published in Dr. Dobb's Journal.

Although certifiably antique, the code did compile on VS 2005 and is a fair representation of what is required to do simple 3D graphics.

I've had a go at improving the interface slightly, introducing double buffering and mouse-based rotation. But I'm not an authority on 3D projection. :(

Would anyone mind having a look at the attached and trying to further improve it? I think that this remains a useful article and should not be lost to the mists of time.
