The software may be called from Fortran programs and from C programs, too. The GR3 Software is an independent software package, you only need the basic control routines of the GR Software. The GR3 Software allows to combine different 3D objects in one area, they may be shown in parallel projection or central projection. Normally you will get a line graph, but you may also get hidden surfaces with shading algorithms.
Stereo projection is also possible.
The example programs exist as source files, there are also some examples for the use in a C program. The ingenious representation of scientific data by visualization techniques is an important goal. Therefore, ZAM develops software oriented along KFA's requirements.
