Cgraf is DEC's implementation of CORE. The same performance problems you experience in GKS we also experience in Cgraf. If you're really looking for a FAST way to get out of your dilemma, you could form a set of graphics-handling routines of your own which would in turn call the host-machine's graphics-handling routines (in the case of the VAXstation, UIS). In this way, you would only be changing the implementation of your graphics "library". However, as some netters will pick-up, this definitely doesn't seem like the _best_ way. As you mentioned, this will also take a good deal of development effort and a pretty good knowledge of UIS. Other than these experiences, I also don't know what else is available and would, too, be interested in alternatives to PHIGS, GKS, and Cgraf. Would X be a reasonable choice (does it give what we need?)? ------- Gil Kloepfer, Jr. U-Net: {decuac,boulder,talcott,sbcs}!icus!limbic!gil ICUS Software Systems Voice: (516) 968-6860 [H] (516) 746-2350 x219 [W] P.O.
