Visual Fortran 6.5 & OpenGL

Hi Mr Miller,
I have a grant in AZTI (San Sebastián, Spain), a technological institute. I’m trying to understand the possibility on programming in Visual Fortran 6.5 to perform graphical elements in OpenGl diectly without passing through Visual Basic or C. It seems possible but I can’t find something teaching how to use OpenGl by Visual Fortran from the beginning. I’m particularly interested on creating grids of elements and paint bathymetries, 2D and 3D velocity vectors and things like that. Could yoy say me anything about this (books, material, courses, tutorial…)? It would be very kind of you.
