F03GL -- modules for using the OpenGL graphics library from Fortran To use this package you need a Fortran 2003 or later compiler. Unpack the files: tar xzvf f03gl.tgz or unzip f03gl.zip The files will be extracted into a new f03gl directory. Change to this directory. Check that the Makefile is set up to use the correct compiler and the appropriate libraries. Also set the GLUT variable for the version of GLUT that you intend to use. Then just run make. This should compile the OpenGL_gl, OpenGL_glu and OpenGL_glut object and module files, and then compile and run the test files, one after the other. You will need to quit from each test before the next one will run. The first three tests are rather boring, but in the last three you can bring up a menu with a right mouse click and change some of the properties of the display. From the f90 code you can see how to do similar things in your own code. These examples are slightly-modified versions of the examples provided with Bill Mitchell's f90gl package. They should run on both 32-bit and 64-bit architectures. Anthony Stone Aleksandar Donev
