[ REQ 5922]: Geomview question

[coughlan at cs.ubc.ca]

Hi,

First of all, thanks for all the work you have put into Geomview.  I'm
just starting to use it now, and it's proving to be very helpful in my
research.  Our grafics lab is currently drafting a letter of support for
you.  Keep up the good work!

I'm currently attempting to write an external module, in which I need to
manipulate a geom that's an OFF file.  I think I need to use the
PolyListFLoad() function.  Are there any example programs that show how
to _manipulate_ the polylist?  Is there any documentation that talks
about functions like GeomFLoad() and the like?  Loading in the geom is
all very nice, but what do you do with it afterwards?

I want to modify the "graffiti" external module, such that you can only
add vertices that are immediate neighbours of the last picked vertex.
To do so, I need topological information for the OFF file on which I'm
"graffiti-ing".

Any help appreciated.  Thanks,
