Hi all,
I did this once but I forgot how.  The IRTC deadline is near and I may
have to trace with two computers.  How can I trace on the second
computer from the bottom up.  When the two images meet, I am done and
just have to stitch them together.

Thanks in advance,
Bob

P.S.
I have already tried...
Start_Row=120 End_Row=1
and
+sr1.0 +er0.00

Something like this in the camera statement:

up -y right -4/3*x sky -y

might do the trick.
