You can also use OpenGL in VB.NET. There are many tutorials on the web like
http://www.activevb.de/tutorials/opengl/tut_ogltutintro/tut_ogltutintro.html(sorry

Which Version 2.0 DOT.NET ? Pixel Shader?
I tried your prog on a graphic card with pixel shader 2 capability by your prog

running. I could not open any model, but there where no complains of your prog.
So at this point I am confused.
