I would like to be able to draw transparent polygons using DEC PHIGS. I've tried various values for the "trans" field in the surface structure that is passed to ppsetsurfprop(), but haven't had any success. The documentation hasn't been very helpful in this regard. Am I missing some obvious "gotcha," or could somebody mail me a short code sample that shows how to get transparency to work? I'm using DEC PHIGS V2.2 on a DS5000 PXG/Turbo running Ultrix 4.1. -- Clauss Strauch Carnegie Mellon University cbs@cs.cmu.edu
