2D image => 3D pair -- which program?

[Paul Schmidinger]

Hi,

please look at this: (not by me)

I can imagine doing this with layers in PS, but it sure'd be very much
work. I wish for a program where I load a 2D base image, and then
directly paint the 3rd dimension into it, creating the dirtorted 2nd
image in real-time. So I'd actually be working in 3D. And ideas?

Internally, the program would work with a grayscale-depth-map, of
course, but I would not need to see it because I see the actual
3D-impression.

I am aware that this method would have some problems, but I think it
could be quite comfortable/fun to sketch the basic depth and fine-tune
the image later with different software...?

Cheers,
Paul

If you look at the image in deviant art its pretty hard to see much depth
detail, so you really don't need to do much. I would use something like
GIMP and select each component on a given depth and copy it over to the
stereo pair image (essentially duplicate size to one side) to the same
location, one GIMP layer per depth value. Next select each layer at a given
depth and translate it the proper amount in the x axis only (this is where
experience and experimentation are important). For objects that project in
z (depth) that will usually be the top or bottom edge so you use the shear
tool in x only and then translate for the proper z alignment. If only a
portion sticks out, eg a nose, you would treat that as a seperate object and
use barrel or pincushion distortion and then again translate on x axis.
Lat, you need to essentially paint a new background and put at the bottom
layer and now add back all the distorted and moved layers on top of that
back to front. As you can see, there is no single magic button program to
do this for you, most of the success or failure comes from your personal
skill.

If it was me, I'd skip all the 2D stuff and use Blender (3d) and projection
painting to make rough 3D shapes, paint your 2D image onto the 3d shapes and
render with stereo camera. OTOH, you think GIMP is hard to learn, blender,
Mwahahaaaaaa!

Good luck
