[comp.sys.sgi] mapw call?

markv@phoenix.Princeton.EDU (Mark T Vandewettering) (08/30/89)

Does anyone have a fragment of sourcecode that utilizes the mapw call
on the silicon graphics?  Or alternatively, how can I get a line in
world coordinates from the corresponding screen coordinates? 

Your help is appreciated.
