Has anyone implemented a `previewer' for NFF files? By `previewer', I mean
a program that eats a NFF scene description and QUICKLY spits out a wireframe
(or some other inexpensive) drawing of the scene.
ASIDE{
Why is such a beastie useful?
For students, it provides a quick way for them to verify that they've
specified
their view parameters correctly, that their objects are in the desired
configuration, etc. I'm teaching graphics to 40 students this semester and
would like (both for their sake and mine) to give them some nice tools
to start with, so they can do something interesting rather than simply
hack code all the time. MTV's ray tracer is a great teaching tool, and
an `el-cheapo' NFF renderer would be a great addition, for those situations
(`prototyping' a scene or sequence of scenes) when speed is more important
than realism.
}
It shouldn't be too hard to write this previewer; I'll probably do it
myself (*gulp*) if nobody else has already, but I thought I'd query the
net before diving in.
Send e-mail or follow up if you have code/suggestions/brickbats.

There is an NFF previewer available for anonymous FTP on gondwana.ecr.mu.oz.au [128.250.1.63] pub/preview.c. It uses the vogle library which is also available as pub/vogle.tar.Z Bernie.

Elapsed time: about 10 hours. If anyone on this side of the pond wants the preview.c program, it's now available for anonymous FTP from shillelagh.cse.nd.edu (129.74.9.7). You can get the VOGLE library from uunet. I tried the previewer; it does what I need. TTFN -- Patrick J. Flynn, Computer Science & Engineering, University of Notre Dame flynn@cse.nd.edu

I've got one that works on HP workstations, if you'd like it. Nothing fancy (the mouse controls viewing a little bit), but it works. Eric Haines, erich@eye.com

There is a NFF previewer for Silicon Graphics workstations available on godzilla.cgl.rmit.oz.au (131.170.14.2). Make sure you grab the readme file also. It uses the hardware lighting and Zbuffer on the SGI machines to give a very fast preview. Mike Gigante ACGC, Royal Melbourne Institute of Technology Melbourne, Australia mg@godzilla.cgl.rmit.oz.au
