QRT SCRIPTS
__________________________________________________________________
*** THIS FILE: ***
There are 6 QRT scripts in this archive, all of which have been
previously released. I have put QRT source and documentation on
a BBS system in Cleveland I routinely call, and from there people
copied them to different Amiga BBSs (which is what I was hoping
would happen). But it seems that no one copied any of the
scripts, so I'm getting quite a few inquiries from people who
want demo scripts for the new features. For this reason, I'm
collecting a few of the better ones into this archive in hopes
that whoever copies QRT around will distribute this, too. Also,
I have gotten some calls from people who have found QRT 1.4 (the
newest verions as of Nov 88), but have old documentation or no
source code. So, to all the people who post QRT to various BBSs,
I ask:
* PLEASE *, COPY ALL OF THE FOLLOWING FILES!!
QRT14.ARC - QRT executable for 1.4
QRTDOC4A.ARC - QRT docs for 1.4
QRTSRC14.ARC - QRT source for 1.4
QRTINP14.ARC - QRT sample inputs for > 1.4
(this archive)
THANK YOU!
If people make an attempt to distribute all this stuff, it will
save me alot of time in responding to people who want source
code, newer docs, etc. Also, quite a few people have only the
older demos (ROOM.QRT, etc), which don't look as nice as the
newer ones. I have also sent a complete version of QRT1.4 to
Fred Fish, so hopefully he'll include it on one of his disks, and
the full system will get wider distribution.
I have so far responded to all QRT inquiries either by mail or
phone, but I have been having some problems with postal service,
so I apologize to anyone if I didn't respond - it was the post
office that messed up, not me. By the way, if anyone comes up
with some nice input files, I'll be happy to include them in a
future version of this file and give you proper credit, if you
send them to me.
As far as I remember, all these scripts will render with 1.4 (I
didn't try them all with 1.4, but versions should be upwardly
compatible). In particular, alot of people have asked me for
demos of glass objects. TABLE.QRT has a nice demo of a glass
topped table that looks pretty slick. Getting nice glass
surfaces requires some playing around, so be patient - the
results are worth it. Also, the REMOVE command is used in
PIANO.QRT to form the piano top. This command is useful for
making arbitrary polygons from parallelograms.
** OTHER NEWS **
A few people have pointed out various bugs in version 1.4. I
thank these people for their efforts, and I will attempt to fix
them in a future release. But I have recently been busy and I
have not done any work on the code since AUG 88, so I don't know
when I'll get around to it. Also, there are a number of users
who claim to have written post processors for various flavors of
IBM's. I don't have the source to any of these, but if somebody
gives me one, I'll release it with a future version. I'd be
interested in hearing from anyone who has ported QRT to other
machines. It aught to look nice on a MAC II, or an HP 825 SRX
(which is a REAL fast RISC based graphics workstation from
Hewlett Packard. Free plug here for HP workstations - if
you're in the market for a Sun 3 or 4, take a look at the HP
stuff.)
KNOWN BUG LIST FOR 1.4
-----------------------
* triangles only work if 2 sides are orthogonal.
* patterns won't map to quadratic surfaces.
* there are a bunch of malloc(strlen(x)) statements which
really should be malloc(strlen(x)+1).
* short focal lengths distort objects near the edges of the
image.
* maybe some more stuff I've forgotten. Again, thanks to
everyone who's pointed out these bugs to me or suggested
enhancements. Sorry about the bugs.
** FINAL NOTE **
A few people have actually contributed money for QRT. These
people I thank, but I stress that this is NOT required. It's
supposed to be FREE, and I don't have the time to maintain a
registered user list or send out new versions in the mail to a
bunch of people. So you'll have to get it from your local BBS
system. And no contribution is required. But I will still try
to respond to serious inquiries, as long as the number of these
doesn't get too great.
