We are considering the GPX as a graphics workstation.  As a fluid modelling
group a large number of graphics images are produced daily.  Each 
image generally contains approximately 100K vectors.  We wish to add
color and produce images more quickly and are wondering about the
capabilities of the GPX.

1. At what speed are vectors drawn by the GPX?  (How was this measured?)

2. What transformations are done in hardware?  Rotation,Scaling,etc.

3. Are namelists supported?

4. Shading and 3-D are not supported?

5. Software support? (GKS, highlevel packages)

Obviously, these questions have been asked of DEC reps.  They have not
been able to supply the answers with any detail and have not gotten back 
to us.  Any information which you can supply would be most appreciated.
Comparisons with other machines are particularly encouraged.  Please
let me know your application so that I can compare with our needs.
Note that an Iris or similar machine would be great, however we are
trying to supply several GPX's for individuals and then maybe an Iris
for group use.  I will summarize to anyone interested.
