1+1=3D

Skill Level: Beginner / Views: 1319 / System Requirements: Just about any version of Poser will do.

Isn't it odd that for all the excitement of 3d modeling and animation applications you still look at a 2d view of the 3d world?I thought so. Using Poser I figured out a better way by setting up a parallel view stereoscopic window that provides an exponentially better option. With one camera parented to another, 4D flying through animated sequences is unparalleled, so to speak. I'm pretty sure you haven't seen anything like it before.It was originally posted on Renderosity a few years ago but it has apparently been misplaced so I'm uploading it again with the hope that it will again inspire others to see for themselves.I can not overstate how much easier it is to place and animate multiple objects in true stereoscopic 3d by eliminating the need to reposition the camera in order to make sure objects are in apparent proximity.

1+1=3D



For the purposes of this (work-in-progess)  demonstration, I'll be describing a method that produces a 400 pixel wide viewing area comprised of two 200-pixel wide views, side by side. 200 pixels is within acceptable parameters for the average human eye (about 2.5 inches) and should be something most people can adapt themselves to, if sufficiently motivated.

It's 2013, 5 years later, and I recently purchased an amazing for what it is stereoscopic still/video camera that I can plug into HDMI anything for less than $200. Projectors are still steep but they are available. I've been puttering in my 3D studio for decades devising stereoscopic exhibits and it's my hope to go full circle and work with an old friend in their new home on the bay, to bring some additional depth to the whole exploring curiosity thing. I hope we can all look forward to it.

PixelPusher2004, First: my experience with Poser is that it renders a single camera view so each view/each frame will be rendered separately. There are a variety of post-production techniques available after that, depending on the results you seek. Second: yes, each camera has a "point at" command. Based on my limited experience with this awesome technique, I suggest you create a separate invisible object for each camera to point at, rather than pointing both at a single invisible object. As you've done with the Cameras, slave the AuxCamera object to the MainCamera object and move it where you want the focus to be. Move the AuxCamera object to make sure your Camera convergence is on the surface of any visible figure and not within it or in front of/beside it. The flexibility will be invaluable for closeups. Talisman, Wow! I appreciate your comments. Flattering and illuminating. I really was trying to serve the community by posting this and I'm gratified to know that it's appreciated. In the early 90s, I was fortunate to have worked at Exploratorium in San Francisco and was able to brainstorm with 3d exhibit developers, among others. That led to this: 1+1=4D: Real Time Stereoscopic Video Projection http://www.youtube.com/watch?v=JbUBSxru1is I'm glad that cartoons are finally! going 3D. I believe we haven't begun to see where stereoscopic video is heading but I predict viable home stereoscopic recording and projection systems in 5 years. Anyway, thanks for the thoughtful and informative comments.

I worked as an photo interpreter for the U.S. Army, and we used stereoscopic viewers, which basically facilitated the cross-eyed view for 3D. In that faux-3D environment, I recall that I only see one, composite image, but a lot of eye-strain and headache goes with the technique. This, too, diminishing over time, however. In the parallel viewing technique, I see one, nice 3D view, and the two satellite 2D views on either side. Once you can stabilize and hold the 3D view, you can easily switch between all three views. I think what is easy for one is maybe not so easy for another, so 3D glasses may be the ticket for those who find it harder to do without assistance. I know, in my stint of military service, that I could generate any 3D view with just the sight of the appropriately-spaced 2D views but some of my fellow interpreters needed the stereoscopic viewer to create the 3D image. To each their own, I say. If the use of Open GL eyeglasses would help, then maybe that should be pursued. The technique that the author of this tutorial tries to present, successfully, I think, is that, for some people, no aids are needed usiing these views. You cna see 3D in real time, with camera motion. You do not have to render anything to see the views; I can generate a 3D view of the mannikin on this website by just focusing properly on it, thru both cross-eye and parallel techniques. I also recognize that this is not necessarily possible for all people. In the service, some people, who wanted to be photo interpreterrs, simply couldn't see in 3D and so failed the qualifying entry tests. So Kuro's point is worth noting: other tools to view the 3D-ness of this technique may be needed for some people. I think, however, that Eye has done us a valuable service when showing us how to create the camera setup. All that is left to us as users is to find the way of emulating the 3D imagee from this useful perspective. I am curious, however, to see how making a movie using two cameras would actually work; a walking sketch would be ever-so-nice with some of my favorite maodels!

2 questions; first, can you render in a split pane?(both images in the same render, or do you have to render 2 images seperatly using the diferent cameras?) second-can you use the "point at" command to aim the cameras?

I think anything useful which enables others to explore REAL 3D is a mighty plus. I am an oldie and true 3D has fascinated me since a little boy. I notice recently that many younger people engaged in art, poser, Geometry 3D, etc., are unaware of stereoscopic art and technique, which is a shame. Tutorials like this one, helps new people explore old ideas with a fresh mind and perspective. Well done! regards Mol http://www.3dcreator.net/ Renderosity Vendor and passionate about visual arts.

When I set up the stereoscopic view, I normally prefer parallel viewing (or diverged eye viewing or the "wall-eyed" method) over cross-eyed, as parallel viewing produces no headache for me. I can not, of course, speak to other peoples experience. Some say it is more difficult than cross-eyed but that is not my experience. It's really no different to me than looking through a parallel view stereoscope with out the device. Suffice it to say, you can set up the view in Poser to be either parallel or cross-eyed as you see fit by simply reversing which camera is in which viewing pane. If you, or any reader, is unfamiliar with the parallel viewing method, it may be understood as having your eyes converge on a distant point beyond the screen while focusing on the closer plane of the two images on the screen, thus, each eye sees a different part of the screen in focus allowing unique views to enter each eye producing the illusion. The cross-eyed method forces your eyes to converge between you and the screen and is notorious for causing eye strain headaches. If there is still a danger of eye fatigue from the parallel viewing method, it is easy enough to resize the window to be smaller, allowing your eyes to converge closer to but still behind the screen. The, for me, persistent superiority of this method is it requires NO ADDITIONAL TECHNOLOGY (lenses or devices of any kind) to model or animate meaning anyone with Poser can do it. Your point is your opinion and that's cool but that this works and is already possible in Poser (and has been for a decade) is a fact which makes it a tool ANYONE CAN USE NOW. In my opinion, that makes it better than state-of-the-art technology I can't afford. I appreciate your comments.

No, my point stands. I'm rather very well versed in 3D Stereoscopics. If I understand you, you are referring to cross-eyed viewing - I don't remember reading anything about anaglyphs or so-called 3D monitors so that's my assumption. Cross-eyed viewing can lead to headaches, migranes, dizziness, nausea. Not that flicker glasses can't do the same under circumstances (such as low refresh rates) or prolonged use. If that is your intention, you should provide a warning concerning that as some people are prone to these symptoms while others just can't cross their eyes (at all or sufficiently) to bring the images together completely. I can do it only for very short stints. I'm not knocking your idea - I love 3D Stereoscopics - but the currently cheapest and best way to do it is with flicker glasses on a sufficiently high refresh rate CRT monitor. Anaglyph glasses aren't bad but you do lose some color information. Headsets and 3D monitors are usually prohibitively expensive.

The complaint escapes me because this functions perfectly. Too bad kuroyume0161 missed the point. Working in Poser I can see a fully stereoscopic view while posing AND while animating WITHOUT any extra technology/glasses/etc. cluttering up the process. The suggestion that OpenGL 3D is somehow more desirable is confusing to me but then I don't generally try to solve problems that aren't problems with solutions that aren't solutions. If anyone has anything to say about the tutorial that relates to the tutorial, I would be interested in that.

kuroyume0161  10:48PM Sun, 01 June 2008

Too bad that these two views cannot be combined via OpenGL 3D Stereoscopics to 'flicker-glasses' or a headset so that you can truly see the stereo depth while working!
