I'm not think of doing it scratch,
the books i cited are ones witch I read in the 90's
I only have Andr? LaMothe's Black Art of 3D Game Programming (on CD with source code) and
Waite Group Press's "Virtual Reality Creations." (no source code) on hand
the others i borrowed from a library
I've talked to the webgl community about this, and their reply was it could be done, without a reference
i am looking for object viewer programs that display models at 640x480

I had often run D.E. WREGE's version of Spacewar! on my PDP-12. But
when I tried to run it on my PDP-8/E with a VC8/E and DEC VT01 (Tek
611), I would get flashing artifacts on the screen in addition to the
normal display.
I initially thought I had a hardware problem - but I could only get my
VC8/E and VT01 combination to fail while running DEC's VC8/E diagnostics
by setting the timing switch on the VC8/E incorrectly.
When I initially looked over the VC8/E code in SPCWAR, it looked O.K.
and I thought the problem was likely in the clock or interrupt code.
After reviewing it extensively and not finding an issue, I tried
multiple hardware clocks (EP, EC) and various VC8/E settings without
success.
Finally, I revisited the VC8/E code in SPCWAR - and the problem turned
out to be a subtle bug in the VC8/E code.
According to DEC's VC8/E writeup in the LAB 8/E manual, a "wait for
done" should be given AFTER the last LOAD command (X or Y) is given and
BEFORE the intensify command. In other words the code should be:
TAD X /Get X coordinate
DILX /Send to VC8/E
TAD Y /Get Y coordinate
DILY /Send to VC8/E
DISD /Skip on done
JMP .-1 /Wait until done
DIXY /Display (Intensify) XY point
...
The original SPCWAR code it was:
Get X
DILX /Send to VC8/E
Get Y
DILY /Send to VC8/E
DIXY /Display (Intensify) XY point
DISD /Skip on done
JMP .-1 /Wait until done
Because of the above coding error, the VC8/E analog output would not
"settle" the correct amount of time (which for a VT01 is about 80
microseconds) because a DIXY command was given immediately after the
DILY. This error created artifacts on the screen because the intensify
command was in effect while the VT01 was still in the process of moving
it's "beam" to the correct location.
BTW: Slower displays, such as the VT01/Tek611/Tek613, do NOT need a
clock to slow down Spacewar to an appropriate speed.
If you would like a copy of the corrected SPCWAR.PA or a listing
(SPCWAR.LS), you can get them via anonymous FTP to bickleywest.com or
via your browser at ftp://bickleywest.com/pdp8_spcwar/
While I was at it, I also added an assembly option to start SPCWAR in
Spaceship mode (per the original Spacewar!) as opposed to UFO mode.
Cheers,
Lyle

Quick question
There are three executables that I know of to copy RK05 disks in OS/8 on a
PDP 8/e.
RXCOPY
RKCOPY
RKUTIL
Using RKCOPY I was able to generate exact copies of the 0 partition only.
Any tips for how to get both partitions to another disk? What's the best
utility. I hate to experiment on someone else's disks too much, doing the
copy for a fellow MARCH club member.
RKA0 --> RKB0
RKA1 --> RKB1
Thanks
Bill
Anyone remember Lotus Improv?
I understand that a version 3.0 was finished, though unreleased, and was a 32-bit application (unlike the final 2.1, which is 16-bit). Anyone know if Improv 3.0 survived?
Thanks!

I would like to see cell shading do an image like this http://www.supernintendoclassics.com/wp-content/uploads/StarFoxNoUpres.png

Yes, I'm running far far behind schedule with our new datacenter buildout. I'm finally to a point where I can start migrating classiccmp-related stuff.
I'll be migrating the classiccmp-related websites that we host first (but not the main classiccmp.org site and subdirectories therein). That will start tonight probably.
Anyone who has classiccmp-related websites hosted on classiccmp.org server, please do not make any changes to content over the next few days - that would make it easier on me. Also, while we provide DNS for most of the domains on that server, there are a few there that are using some other dns servers. If that is the case, please make an effort to respond quickly with regards to changes in A records.
Several people contacted me a month or two ago about hosting additional classiccmp-related sites. I have those emails in a separate mailbox and will be getting back to each of you after the final classiccmp migration is done.
After the websites are moved, but before I get ready to migrate the mailman/list setup, I'll post another update at that point so you're aware of the impending migration.
Best,
Jay
