Poser - OFFICIAL F.A.Q (Last Updated: 2024 Dec 23 7:38 pm)
Increase the 3D effect by increasing the yOrbit value.
Note - You may need to reverse the images right to left to get the proper effect.

For the life of me I couldn't understand the camera measurements - trying to move it 2.5" using the camera options drove me mental ! Instead I just moved the camera to the right bit by bit then combined the images in PSP to see what result I got.
I'm not sure "orbiting" the camera along "Y" would work, as I understand it, you would be revolving the camera around a centerpoint. Eyes are next to each other, not set on a concave curve.
Anyway, I could be wrong, but here is the result of moving the camera to the right. Sorry, not sure how many units it was, I was just doing it as a test.
ETA: The second image is on the left.
Trivial.
Have the camera "point at" a dummy prop - any prop will do - I use a ball. This ball is the eye "focus point" - the position in space that the two "eyes" are looking.
You move this ball then hide it to keep the two cameras in sync.
Now, you can use your regular cameras, but I prefer to create a new pair of cameras for stereo. I make dolly cameras.
Position them both at 0,0,0 initially. Move one to X=k/2 where k is the inter-ocular distance you want. For exact human vision, use a realistic value. Move the other to X = -k/2.
Pick one to be the master, and parent the other one to it. This way, when you move the master camera, the slave will follow.
Have both cameras "point at" your focal target ball.

In Geeps render, he got the cameras reversed. Watch out for that when you put the images together.
For cross-eyed viewing, the image on the left is what the right eye sees.
Because he got them reversed, the central figure produces a visual paradox. From cues of a single image, he's behind the other two, but the stereo parallax places him in front. Swap them and all is well.

did you just learn all of that in 5 minutes or have you already been rendering 3D before?
so if i understand right the convergence is the length from the camera to the dummy ball(point at). for example if i have a human and a car infront of him. if i point at the human then the car will be in positive 3D. if i point at the car then the car will be on the zero and the human in negative 3D?

Sorry, guess I got 'em bass ackwards, it was a 50/50 proposition and ...
Haste makes was ... er, makes 'em backwards.
It's sort of like ... reversed normals, no?! :lol:

what does x= k/2 mean?
for example if k is 2.5 then i do 2,5/2 on the x dolly?
Dolly cam A 1.25 on x and Cam B -1.25 on x
I've done a few of these and they're always quite cool to see. This one has settings of x dolly 0.125, yrot -2 for the left image and xdol -0.125, yrot 2 for the right.

If you move it to the right and then turn it to the left, it's functioning like the right eye -- which the brain reads as left. Go figure... LOL
docandraider.com -- the collected cartoons of Doc and Raider
The brain takes the two signals from the eyes and reverses them -- TTTT, they go into the brain upside down and reversed, and the brain "fixes" it by putting the image back together. But for that to work, what's in the right eye gets "translated" into something that appears to come from the left.
When you think about everything involved, sight is a bloody miracle.

The cross eyed viewing means that your right eye observes the image on the left. In the stereo pair, put the image for the right eye on the left. It does not look like it is viewed from the left - it looks like it is viewed from the right. This is correct because the right eye is pointed at the left image when you look at it cross-eyed.

Ice-boy, just cross your eyes until you see three images, look at the one in the middle...
Actually I prefer to view such stereoscopic images by relaxing the eyes rather than crossing them.. in other words, position the eyes as if you are looking right through the screen at something in the distance. I find it gives a more satisfying stereoscopic effect and is much more comfortable to hold.
This method of viewing means that the image for each eye needs to be on the same side, not opposite sides. I.e. image for the right eye is the one on the right.
It does mean that the images cannot, in practice, be further apart than your inter-occular distance, or you can't get the two images aligned correctly. Geep's images (both of them!) and the light bulb image work very well this way and produce excellent stereoscopic effects.
Geep - you simply reversed your whole image, which doesn't actually make any difference to the way it should be viewed. In order to view it cross-eyed, the left and right halves of the image need to be swapped over, but not flipped.

Also.. the giraffe is a pretty good example of the cross-eyed method. But the memorial is a bad example, because the two camera positions are too far apart, I think.

Quote - This technique can be harmful to your eyes
If you do it too much, sure. But given that we naturally cross our eyes to change focus from thjings far away to those near, I dont think it's worth worrying too much about.

4 years ago i made something stereoscopic for Poser. There is still a PDF here with some description: http://www.poserprofis.de
While poking through the bones of the now defunct poserpython.com, I happened across a python script to create a stereoscopic pair of cameras. The file downloads fine, but I haven't yet tried it, myself.

BTW, I get 50% more negative waves from The Nay Say Guy in when he's in 3D. I need to go have a drink...

My mind is going, Geep. I can feel it... Daisy, Daisy, give me your answer do..........................

The Wisdom of bagginsbill:
"Oh - the manual says that? I have never read the manual - this must be why."i made now a test. i rendered the same image two times. the first one is the one that i posted. the point of convergence is on the figure. in the second render i put the point of convergence on the wall behind the figure.
i was reading somewhere that if you use differencet points of convergence that the 3D looks different. but in my examples it didnt look different. i forgot to save the renders so i can not post them.
does anyone ahe an answer?

seanmartin please excuse me for using your image.
No problem. That's pretty cool.

Quote - my first example.
the point of convergence is on the figure. for the inter ocula 2.5.
The problem with this, as I'm looking at it, is that the figure remains flat, like those late-generation Viewmaster reels.

Their eyes are on the sides of their head giving them a huge field of vision with very little if any overlap for parallax in the middle directly in front of them... bobbing the head gives them sequential parallax on those wide side fields of vision covered only by one eye. Or so I am told ;) Sounds good to me in any case. An alternative explanation for why they bob their heads even when standing still is that they are just always listening to a really groovy soundtrack in their heads.
Pigeons bob to stabilize the visual field. As the body moves forward, the head holds still then quickly thrusts forward and re-establishes near zero motion as quickly as possible.
Pigeons don't bob their heads when standing still, nor when walking on a treadmill. They do bob when coming in for a landing in time with the wing beats, again to cancel their motion and stabilize the visual field on the retina.

after watching the movie Avatar i found on the internet ''cross eye'' 3D images.
in this link its explained everything. how you watch cross eye 3D pics.
www.neilcreek.com/blog/2008/02/28/how-to-see-3d-photos/
for 3D pics or 3D movies you need two images with different camera angle. like humans eyes see from a different angle. the difference is very small.
Inter Ocular Distance:
The distance between the centers of rotation of the eyeballs of an individual or between the oculars of optical instruments.
stereoscopic convergence:
The stereoscopic convergence is adjusted in stereoscopic imaging equipment to increase or decrease the stereoscopic convergence angle. Two imaging devices are disposed symmetrically relative to a median optical axis to generate video signals representing images of an observed scene. Depending on the required stereoscopic convergence angle, two image "read windows" are positioned symmetrically relative to the median optical axis, each being defined by a first pixel and a last pixel of a processed image line.
so if i understand this right now. inter ocular distance is the distance between our left and right eye. the bigger the inter ocular distance is the more 3D effect we have.
the convergence is the point in the 3D space where we want to point at. we decide from where on we have positive 3D effect and negative 3D effect?
am i correct?
