	I am currently writing a program which defines three dimensional
objects which are generated by defining a 2-D polygon which is swept around 
an axis or extruded along an axis. Now I am looking at shading the
3-D objects that I have created. 

I have not had much experience with shading, and so I would be very grateful 
if anyone could send me information,'C' code or algorithms which perform  
Gourand shading (or similar) on 3_D objects.

Any advice would be welcomed.

Please email to cpgrb@marlin.jcu.edu.au
