MW: It's difficult to explain, but when you're making stereo images (photos, screenshots, whatever) there is a "window" into the scene and this window corresponds with your viewing device (a monitor, a projector screen, etc.) Objects appear to be either behind the window or in front of it ("bulging out" as it were). This "window" is artificial and a result of how the left and right eye image are cropped (changing how they are cropped and how they will overlap each other in the final stereo image effects the position of the "window" or, in other words, whether objects in the scene appear in "front" of or "behind" the screen).

Whether or not objects "stick out" is somewhat an aesthetic choice. Purists may argue that the image isn't "correct" unless everything appears behind the screen. With some of my 3D images I have chosen to have objects sticking out in order to give it more of a "wow" effect. The only real reason to not do this is if you have an object that sticks out but crosses the edge of the picture. If this happens the 3D will look funny to your brain because you expect the object to continue on past the edge of the picture yet it just abruptly stops. If you adjust the image so that you push all the objects "behind" the stereo "window" then it looks like you're looking through a portal onto a scene and when objects extend to the edge of the picture they won't look unnatural because your brain assumes you can't see the rest of it because it is behind the "wall" around your "window".

Phew. Like I said, it's complicated :)

Thanks for posting this Kato. I've been making a 3D animated movie by hand in photoshop using 3D homemade gifs converted into Avi files. Thank you for showing me those other programs, it's going to make things alot easier. I do have a question if know.. Why is it that most pictures look like your looking inside though nothing is coming out of the screen though with your pictures clearly there is some bulge? :P

i understand how to get the footage just not about how i would convert both movies (left eye and right eye) into one 3d movie, if i would have to do it frame by frame(like film the movie, convert it into X bitmaps and convert them all, then put them back, or if there is a way to load the right eye movie and the left eye movie the same way as you load left and right eye photos

2008-03-03T15:28:00.000-05:00

Glad it was helpful.

In regards to your video question. You could do a 3D video, but you would have to be content with having a video in which the camera doesn't move/zoom. You could set up the camera someplace and record a video, then move it slightly left or right and record a second video, but you can't move the camera during the video or else you will ruin your 3D shot.

thank you so much! this was very helpfull, i had a question though, is there a way to upload say, 2 videos, and do the stero image thing with the red and blue to the whole video, or would i have to just do it pic by pic,

also i made some halo 3 pics and even some real life ones! (nothing bad just things like pop cans)

2008-02-10T18:40:00.000-05:00

There is an even EASIER way to do this. If you want to play PC games in 3D rather than just get images of them, go to mtbs3D.com and download the latest iZ3D 1.07 drivers. They are meant for iZ3D monitors, but they have an anaglyph (red/blue) mode option. You can create screen shots from that too. There is also an entire gallery there filled with stereoscopic game screen-shots in cross-eyed view that can be converted to anaglyph if you want.

2007-12-10T18:19:00.000-05:00

Nick,

Don't worry too much about getting exactly 2.95% distance between the shots. That number was derived through some trial and error and some calculations. Feel free to try a smaller separation, or larger one, if it gives you better results.

The 2.95% separation is along the width (long dimension) of the display.

If you are having trouble moving the camera the width you want consistently, do what I did: create a guide. Get two lengths of string (or dental floss in my case) and cut them so they are a few inches longer than the height of your TV. Find something to tie to one end of each to weigh them down (screw, nail, bolt, whatever). Find something else sturdy to attach them too--a small block of wood is nice, but I made do with a bit of cardboard that I weighted down by taping on some coins. Attach the lengths of string to the block of wood (or whatever) such that they are the appropriate distance apart (2.95% of the width of your display, which is probably a couple of centimeters) and so that the "weights" are on the unattached ends. When you're done you should have a little guide you can put on top of your TV that will hang down two strings across the screen. Line up something in the picture with one of the strings and take one shot, then line that same bit up with the other string and take your second shot.

I made a few 3D screenshots by following your guide, but I am having trouble getting the camera movement distance correct. I guess I'll have to try to measure the 2.95% more accurately. Also, does the 2.95% actually refer to the "width" (technically the "height" is the shorter distance, while the base is the length) of the TV, or is it actually the "length"?

the jonez: Cool pics, though it looks like your left and right eyes are swapped. Easy enough to fix, though, if you still have the source images.

tina: Are you loading in a picture for both the left and right eyes into Stereo Photo Maker? That picture looks kinda like a single image forced into a left and right eye image.

2007-11-07T14:33:00.000-05:00

Yes, but you don't really need two people. Just take your film into the theater, cue the player up to the right part, move your camera somewhere appropriate, then hit play and record it (interpret that as you will--more than likely this involves video capture into a PC). When you're done, reset the film to the same start point and move your camera for the second eye and do it again. The only limitation is that you have to "stationary" clips this way (that is to say, your cameras can't move during the segment you're recording because it would be nigh on impossible to synchronize).

how bout some rampant speculative ideas...

what if we have a scene in forge, where 2 players are the monitor and are spaced eye-width apart in a fixed position. both record a short video scene, like a nade stick. can frames be extracted from those 2 videos and used to make a 3d video clip?

Anon 1: Glad you were able to understand my wordy instructions. Feel free to post a link to your work if you have uploaded them someplace. And thanks for the code... I'll have to try it out. Though I'm not sure I have enough digits to hit all those buttons at once.

Anon2: I use flickr and they look fine as JPGs there. I usually save mine as either PNGs or as JPGs set to be lossless (as described in the article) and flickr doesn't seem to add too many compression artifacts (but it will if you try to upload BMPs... something about how they reformat them). You could also try Photobucket, should work there too.

It looks terrible as a .jpg

Can someone help me out with this?
