Even better than the 3D Meninas

Awesome hack. I don't really have any application for this, though.

dagw• 16 years ago

Well I can think of a use or two for the bird example, but I'm unsure why I'd want to use this method over something javascript based.

Why are you interested in hacks? What's wrong with using better tech such as OpenGL?

Did you notice the name of this site? (And yes, for practical purposes OpenGL can be better.)

I think it could be used on any kind of catalog page to allow users to rotate the product image. Wonder what it would take to add a vertical scroll so you could rotate it in any direction. This kind of image manipulation is something I have no experience in.

This experiment is definitely worthy of a post. I haven't looked at how he did that or the "CSS Bird" shadow effect but I'm impressed that can be done without Javascript.

The other examples on his blog are even cooler... check this out. http://www.romancortes.com/blog/css-3d-meninas/

And that one points to an explanation of the method, with diagrams and the partial pictures used:

Strange, I had to refresh the page twice to get the effect to work correctly in Chrome. Each time it worked progressively better!

Nice effect.

I think a bit of JS is being used to create the DIV structure, but that's not important.

It could also be improved a bit: you could remove the shading gradient from the Coke can mask PNG, and render the shading using an CSS gradient with RGBA values. That would mimic the specular highlighting, and you could also animate the shading.

I still haven't quite grok'd the displacement method though... it must be carefully calculated background x pos offsets? (I don't have firebug on this machine)

morphir• 16 years ago

I got js disabled. And the effect worked fine.

flog2• 16 years ago

Yep, cool - it just means a lot of empty div structures (n * width) to contain the samples... I assumed JS as it would have been more efficient.

No scripting. Here's a direct link to the effect page:

Looks like it's just slicing up a wraparound texture vertically -- no scaling, just subsampling. The can and highlight are just composited on top. Slick and clever.

Note that it's really not "3D" in a meaningful sense. It's doing pixel-aligned warping only, and is hard-coded to a cylinder (any "lathe" shape would also work). This is the same trick that the Amiga used for the bouncing ball in 1985.

Seems cpu intensive :) Server down.

tvon2• 16 years ago

Were it CPU intensive it would be so on the client side and have no affect on the server, and fwiw, scrolling back and forth quickly I saw no cpu spike (fairly new MBP, granted).

It's more likely that the site has been taken down by being posted on sites like HN/reddit/digg/etc (it was easier when we could just say it was "the /. effect").

vinhboy• 16 years ago

Wow amazing. Now I feel like a total CSS noob.

sscheper• 16 years ago

That looks great. No trying to be a dick, but what's the point?

tvon2• 16 years ago

To demonstrate cool shit you can do with CSS.

dtegart• 16 years ago

Well the first time you do it to see if you can, the second time because you can and the third time you use it to see if you can do something else

nobosh• 16 years ago

This is slick. I wonder how long it took to build that image/

sandGorgon• 16 years ago

wow!

PROTIP: Try hiding the the width and the float on p and/or the padding and width on the 'div div' with firebug.

faramarz• 16 years ago

Very cool. My question is.. how did he scan the coke-can? http://www.romancortes.com/ficheros/coke-label.jpg

javanix• 16 years ago

I bet you could do it without "scanning it" per se.

Taking a set of pictures and then using stitching software, followed by some Photoshop touch-ups would probably give you a pretty good start.

ElbertF• 16 years ago

Perhaps he cut it open.
