The openGL gsurf library (ogsf), consisting of approximately 20,000 lines 
of C code, contains some 180 public functions and about twice as many 
internal functions for run-time data storage, manipulation, querying, 
and visualization using OpenGL.
The library handles all drawing and lighting operations, including use of
user-defined clipping planes and drawing various style "fences" on clipping
planes when drawing multiple surfaces, and treats datasets as objects which
can be used for various attributes of the rendering.  It allows data 
sharing (e.g., same data for more than one attribute of same or different 
surfaces), separate masking for each surface, multiple surfaces, vector
sets, or point sets, and will also allow multiple volumes.  The library 
provides all query features such as 3D "point on surface", keyframe animation
routines, and full state saving functionality.  Database-specific routines 
for interfacing with the GRASS GISlib are kept isolated for easier library 
reuse  with other databases.  The gsurf library is not dependent upon any
particular  interface library, and has been used successfully with both 
Motif and Tcl/Tk. 
It is used for NVIZ visualization tool.
---------------

The library is described in GRASS 5 programmer's manual (get latest version,
probably via CVS:
cvs -z3 co progmangrass50
)

Andreas, thanks for your comments!
