The G3S (three-dimensional geometry support library) was meant as a
three-dimensional equivalent to the G2S module. However, the functionality that
is implemented is restricted to the reading and writing of three-dimensional
geometries. The library defines compound data structures that reflect all lists that
comprise a three-dimensional geometry (points, lines, faces, solids, boundaries,
segments, and geometries) . By providing only one read and one write function
details of the underlying PAL function calls and of the memory management are
hidden from the user. Again, by defining distinct data structures, other high level
libraries are not utilized.
