GDI+ 3D Demo using C#

I have programming computers since before the first IBM PC was introduced in the Forth language on STD Bus systems and then Microsoft BASIC, DOS, QuickBasic and QuickC. Later, my most interesting and productive work was on Commodore64 and the Amiga computers. I recently started programming again and while recuperating from cancer surgery got deeply interested in C#.
I have been employed in various electronics occupations for 30 years and presently work for a company that manufactures and analyzes radiation dosimeters for professionals in nuclear power plants and research and also dosimeters for nuclear medicine personnel. Any spare time is spent in enjoying cigars, motorcycles and now, learning C# programming, GDI+ and OpenGL.
