[Groff] Perspective in Pic

[Miklos Somogyi]

Ted,

If you want to do 3d in groff, I think that PS is better suited for 
this than Pic.
Here you can define an object in its own co-ordinate system, introduce
modelling transformations to help in putting together complex objects 
from simple
elements, and viewing transformations to rotate the object for viewing
without changing its coordinates.

This is one of my old slides:

PS. Fellas, I haven't received a single post from this forum for a 
very-very long time.
How do you manage? Do you check the archives all the time or your ISP 
is not taking
SpamCop so seriously as mine?
