Thanks for the info on the normalize options.  In response to your
questions about my bug report (???), when the sequence normalize option
was chosen, the machince locked up, ie. mouse didn't work, it didn't
answer a ping over the network, we had to reboot it (this happened 3
times the same way).  I'll play with that a little bit more and let you
know the EXACT sequence of events that occur to make things freeze up.

(We are only running IRIX System V Release 3.3.2.  Would an upgrade to
4.?.? make a difference?)


I have a couple of more questions:

Is there anyway to normalize a group of objects the same way, or perhaps
in a collection of objects, have all objects normalized the same way as
the first object loaded?  Currently, we have three objects - each color
coded.  We are not using any normalization because we want two of them
imposed upon the other.  The problem that occurs with this approach is
that it makes it extremely difficult to rotate the three objects
together to get the perspective we need.

What exactly is each slider doing in the 4-D Rotate module?  Are they
specifying a normal direction somehow for a projection into 3D?  What
precisely do the labels mean:

x-w

y-w

z-w

wt

I assume that x-w, y-w, z-w are specifying a normal direction using three
angles.   If this is so, then what does the wt slider do?

Thanks,

Eric Nielsen
