Platform issues

The mesh generation and computation packages are usually written in pure standard Fortran, C, or as in the case of the implementation that we used for research, in C++. They are not dependent on operating system or hardware, and they are actually run on a large scale of computers. Visualisation, and computer graphics in general, however, strongly relies on hardware. Although it is not a necessity to do the calculations and the display on the same computer, it was a priority to maintain platform independence in both modules. Therefore, OpenGL was used to render everything displayed, including the graphic user interface elements.
