[ REQ 5517]: Display question

[sgupta at umbc.edu]

Hi

I have been using Geomview to display hollow extrusions. I use the .off
format to diplay various faces. When the extrusion is bent, however,
the faces in the bent segments become conic surfaces. When I use the
.off format to specify the vertices at the beginning and end of a bent segment,
these (the vertices) are joined by straight lines only, thereby giving me
planar faces instead of conics.

So my question is: What would be the best way to display such parts, which
have lets say, alternating straight and bent segments, so that the bent segments can be displayed accurately?

A further extension to this question is: What is the most general way to
represent any surface, i.e. a general swept surface for example?

Also, do you maintain any FAQ list or some such thing, so that I don't have
to bother you every time I have a question?

Thanks a lot. Really appreciate your help.
