Recently the OpenGL Architecture Review Board approved the Fortran 90
bindings for the OpenGL 2D and 3D graphics library.  These bindings are
defined in NISTIR 6134 "A Fortran 90 Interface for OpenGL: Revised
January 1998", which is available at the web site below.

I am pleased to announce the availability of f90gl version 1.1, a public
domain implementation of the OpenGL Fortran 90 bindings.  This version
implements the interface for OpenGL 1.1 (or Mesa), GLU 1.2, GLUT 3.6 and
several OpenGL extensions.  It supports most Unix workstations and
Windows 95/NT.

OpenGL is a software interface for applications to generate interactive 2D
and 3D computer graphics.  OpenGL is designed to be independent of operating
system, window system, and hardware operations, and is supported by many
vendors.  The OpenGL Fortran 90 bindings represents a significant development
for scientific visualization in the Fortran community.  Until now there has
never been an industry standard for generating graphics from Fortran programs;
instead, only proprietary libraries that support a limited number of systems
have been available.  With the new bindings, a Fortran programmer can write
standard-conforming graphics applications that will be portable over most
computing platforms.

More information and the f90gl package are available at the f90gl web page.
