(At the Movies) 3D in AE
on Nov 18, 2010 at 12:04:51 pm

Hi All,

I was lucky enough to watch Jackass 3-D this weekend, which was a treat, and I even got to keep my 3-D glasses, so it got me thinking...

During the movie, when I took off my glasses, it seemed like there were just two images ofset, one less opaque than the other.

Is it more complicated than this, or is there a way in AE to duplicate a comp that you wanted to be 3-D and offset the position and change the opacity?

Thanks,
Clint

ideally you'd have a two cameras shooting the shot, but offset by horizontally by about the distance between two eyes (i'm sure there is a magic number for this).

the two shots then get combined and then there is some form of glasses that separate the combined image so that the left eye will see the footage from the left camera and the right eye sees the footage from the right camera.

however there are some ways to fake it (to a certain degree), check out the three part ae tutorial here:

Hi Kevin,

Yeah, I was kind of thinking about that... In particular I was thinking of Andrew Kramer's SureTarget plugin, but instead of having one camera, having two, side-by-side.

Then you could render out the comp using each camera and then blend the resulting files together... but I'm sure there's more science behind it.

Also, how do they do the 3-D (like at the movie theater) that isn't the old-school blue and red?


Thanks,
Clint

i think a lot of the current movies are using polarized glasses to separate the left and right images. there are other technologies out there but most of them have the same concept of two image combined into one, then separated by glasses.

your idea with two 3d cameras will work. it's a matter of getting the distance between them set up correctly. possibly a little tweaking of the point of interests, but i'm not sure.

for testing purposes in ae, i think i'd go with the red/blue cardboard glasses. they are cheap and easy to find, and you can easily work with ae's 3d glasses effect for test.

if you needed to deliver another format, then you could still use the renders from each camera, they would just need to be combined in a different way.
