There are plenty of resources online for OpenGL in C, which would be available from our C/C++ compiler.   However, I suspect you're interested in using OpenGL from Fortran.  We don't provide a Fortran wrapper with a stock installation of Simply Fortran for OpenGL.  I would suggest trying F03GL with Simply Fortran.   It provides a modern Fortran interface to OpenGL functions.  Basically, it defines the necessary interfaces to the C functions in Fortran along with defining all the OpenGL constants as parameters.

You can either try compiling it yourself from their home page or, if you have a package manager account, installing our package.   Once installed, almost any OpenGL program, translated to Fortran, should work fine.

Does that answer your question?  Sorry for the long delay in a response.
