While I did not design the algorithm, I've been playing around with the
StereoscoPy open source codebase to create
anaglyph 3D
images. I've talked about my interest in anaglyph 3D before with my
Positive and Negative Planes Concept so it was fun to do this. I actually bought red and cyan glasses to
try this out (you can find them pretty cheap online).
The results are by no means perfect, but short of designing it from scratch with anaglyph 3D in mind, the fact that it works at all and I can more or less automate it is pretty cool.
How does Anaglyph 3D Work?
Anaglyph 3D takes two images offset from each other, like imagine a photo
of a scene, and a subsequent photo taken from a foot to the left, or
something like that. It then aligns and merges the images, and color codes
them, most frequently with red and cyan. Then, when wearing red and cyan
lenses, the respective colors are filtered from one eye or the other, such
that your eyes receive competing information that makes it appear 3D.
Tbf since I did not code the algorithm myself, this is a bit of a weak
sauce explanation, this is among the reasons why I prefer to do things from scratch like with my Genetic Algorithm that Learns the Konami Code, but for now this is fine.
Anyway, after installing that StereoscoPy module, and after experimenting with several different parameters, I used the following
command to generate an anaglyph 3D version of the MRD Cover:
StereoscoPy -A -S 20 0 -a ./MRD_Cover.jpg ./MRD_Cover.jpg
./MRD_Anaglyph.jpg
Rather than using two images, I just used the one cover, but offset it to
the left (-S 10), and used their auto-alignment algorithm (-A).
In addition to installing this module with the auto-align optional
dependencies, I did also have to install some linux packages for this to
work, and only was able to figure that out by tracing some errors and
googling around, so it's not as user-friendly as it could be. Perhaps I
could submit a PR to make it more user friendly, in lieu of writing it from
scratch...
Maximum Recursion Depth in 3D!!!
Reminder that this requires red and cyan glasses.

Dammit, where are the 3-D specs when you need 'em! Supercool that you did this!
ReplyDeleteI have three pairs now lol.
DeleteNever know what we're gonna get at W&WW from post to post - extremely potent blogging style, contra algorithm-friendly consistency.
ReplyDeleteYa it's ironic that I'm probably one of the least algorithmically traceable or SEO friendly blogs despite being probably one of the least bothered by the idea of that haha. My brain and writing is intuitively anti-patterned. Oh dang this is actually a really cool idea! It's like those anti-psycker warp people from WH40K but for cracking cybernetic systems! Damn imma have to think more about this...
DeleteI must now go and steal from my local theater, or perhaps I can salvage some red and cyan spectacles from the abandoned theater downtown... Surely nothing horrible will happen to me...
ReplyDeleteYa they're pretty old school so I wasn't sure how accessible they'd be but you can actually find them pretty easily online. But if you can find some old theater ones that should work too haha.
