This will permit you to write your graphic display code using familiar IRIS graphic calls in FORTRAN or C on the VAX, link this to your application code, and run it on the VAX. As you generate graphics information, it is sent to the IRIS which is running a terminal emulation program (thus becoming a fancy terminal to the VAX). We have linked a MicroVaxII running ULTRIX to our IRIS this way on a TCP/IP LAN. It has the advantage of eliminating the need to build a graphic data output file, the data transfer step, and the need for a separate graphics display program to be written on the IRIS. A disadvantage is that your graphics display speed will be paced by the VAX, which may or not be a problem in your application. I know the RGL is available for VMS systems, but am not sure about XNS network support, though this is easily checked by a call to your friendly supplier.
