#Red/Blue 3D Render tools
11 messages in this thread
Has anyone had any experience with generating 3D files that use the red and
blue glasses to provide a 3D effect? I have a client that wants a few segments
of this in a video I'm working on. If anyone has information on how well this
works and under what circumstances it works best I would appreciate your help.
If you also know what is required to achieve this effect that would also be
_very_ helpful. Does this require a special post process or can it be done from
the renderer and vpost?
Thanks for any help or information.

Make sure you search the library for files with the keyword STEREO. You might
be able to get info from there, as well as make a note of the uploader's CI$ ID
for further info.
Thanks Nik…
Also be sure to go to GRAPHDEV and ask more about stereo imaging.

Tom,
I am currently playing with this effect myself, but only on a still
image.
I am using a Windows program called "3D Maker" from Synthonics, Inc.
(Westlake Village, CA ph# 1.818.707.6000) to do my red\blue
conversions. Ads for it are frequently in "New Media" magazine (they
are the ads in the back with REALLY lame looking elf or troll heads
rotating down the margin).
3D Maker is extremely fast, but might be difficult to use over a
series of animation frames, because it only works with still images
and not animation files. The process is fairly simple, load a right
view, load a left view, set stationary points in both views and hit
the 'Make 3D' button. It then generates a full color (kinda') stereo
image using red and blue overlapping.
I have found that when rendering both eye views that wide-angle camera
lens' don't work because the object distortion on the outside edges
is too great for the 3D stereo overlap to work correctly. I have had
to really tame down my left and right views to get proper 3D.
I hope this will help in some way. You might want to give Synthonics a
call and see if they have any suggestions.

Thanks for the reply Sean, I've seen the ads…
I was looking for an automated process that I could use from VP since I'll have
several hundred frames to do if I go with the idea. If I have to do it by hand,
one frame at a time, the idea goes to the bit bucket…

Hi Tom,
I've played with red/blue stereo a little using 3DS alone.
I made left and right cameras, rendered an all-red left view and an
all-blue right view, and used videopost to combine the views with the
front one 50% transparant. (I made a single camera straight up in
the top viewport, then move/copied the camera a little to the left
and right) I switched materials for the different views. I could
never get the red exactly right for my cheap (is there any other
kind?) red/blue glasses when rendering for video, but the results on
the computer monitor were pretty good. An animation should be no
problem.
BTW, this won't help with your problem, but for a cool 3D stereo
effect right on your monitor, try this… Put the right camera view
in the bottom left viewport, the left camera view in the bottom right
viewport, and view the wireframe in the monitor directly with the
crossed-eyes technique. Instant beautiful stereo wireframes! (Use
Backface) The viewport sizes are just about right on my 20" monitor
at normal viewing distances. You can even view stereo wireframe
animations (moving or rotating the scene instead of the cameras).
Unfortunately, you can't click the >> button since this makes the
active viewport full-screen, but you can hold down the > key on the
keyboard to animate the stereo scene.

John, thanks for the reply, I'm begining to think this was a bad idea.
I've toyed with the idea of doing this ever since I got a paper from
Lawrence Livermore back in 1989. (their paper was on still frame
simple stuff). I was hoping there would be some automated way of
producing the effect. This is for a trade show video that would be on
a 70" screen. The idea was as a gimmick, but it sound like I'd kill
myself on the rendering side for just a gimmick. Guess I'll go for
flashier 3D stuff and leave the 3D stereo stuff to the old B movies.
John, I'll be at NAB if your around I may run into you around one of
the mutually interesting exhibits. Adesk, DPS etc..
>>NAB…
I'll not make it to NAB, but perhaps at Siggraph? I'm spending this week
sawing and hammering pressure-treated lumber.

I 'spose I should come help you. You did, after all, help me put a few walls
up, while you Supposedly were here on Vacation. A nail for a nail and all that.
We're just back from Mexico, and Rocky's room awaits my Next Batch of
spare time. Spare time after a vacation: Heee Hee.
Have you ever used those models you showed me when you were here?
J the B,
What a difficult life you lead. Confined to the horrible living
conditions of whitewater on the edge of wilderness, subject to all
those nasty elk and eagle intrusions, and now this – suffering thru a
vacation in Mexico. You po' fell'r! We need to get some of the
normal 3DS'ers to send you some LA smog, Potomac river water, and a
batch of flying logos to work on.
After adding a basketball goal to our estate, I'm building some
additional wooden fence to keep the ball-chase time to a minimum. I
just finished several animation projects and decided to take a
break. I did, however, <guilty look> <averted gaze> model the
addition and deck section it attaches to in 3DS for a walk-around
just to show my wife what it would look like. My last video client
saw it and commented on how few people in the world could, on a whim,
expend the resources to have a 3D graphics model and animation done
of a small project like this. Yikes, I'm starting to take 3DS & me
for granted!
The nail exchange seems imappropriate. If I remember correctly, I
mostly stood around the Rock Room project site running at the mouth
and preventing you from putting in an honest day's work. A fair
warning is in order: I'll be in your state in June and may
accidentally swing by for a surprise inspection of the Completed
Facility. <g> I've got you tagged on the GPS.
The models were completed, forwarded, and subsequently animated and
delivered. I have a tape.
