lets see- i wonder if you could take a 3d scan of a scene (still or moving) and then superimpose a 3d lattice of white lines or something, and automatically generate the correct occlusion? that would make this effect very precise. that might be kind of cool. sort of like projecting a 2d lattice on a golf green to read the break

well that effect is cognitively bookmarked for the next hackathon. Presumably it will work in games if used sparingly.

This would be pretty easy to do in games since you have all the z-buffer info already. I'm thinking of a HUD that has multiple horizontal "monitors" that show you the action. Then when things get close, they pop out of the monitors for the 3D effect. That would be awesome!

Earlier quoted context omitted.

Basically: GIFs autoplay on people's Tumblr dashboards, proper video formats don't, and that's pretty much all people are trying to achieve in the first place. If we just had some sort of file-extension/media-type (.webg, maybe?) that signalled to a browser "I'm a video container, but treat me like a gif, by defaulting to autoplaying, looping, and muting me", we'd replace gifs instantly.

Video tag autoplays on any site where you have control over HTML. For example on Blogger. Can't say anything about Tumblr - never used it. You don't need any special containers. Just use video tag properly, it covers all that functionality since the beginning: https://developer.mozilla.org/docs/Web/HTML/Element/video Something like Muting can also be simply achieved by making audio empty in the video if you need to.

Yes, that's why I mentioned Tumblr in particular. Tumblr is an example of a website where people write HTML, yet don't control the HTML that displays to others.

On sites where you control the HTML, like Wordpress, you can do whatever you like. Use tags if you know them. Likewise, on sites where you don't write HTML (e.g. Facebook, as another poster mentioned), tags are fine--because people don't have to know about them, so it's all just handled in the background when you drop a video on the page.

But there are these in-between web services where HTML is used, usually as one method of several, to get rich text from people, and then presented in an aggregate view (think of any traditional threaded forum.)

Because people can do some pretty nasty things when you inject their HTML directly into your pages, you have to filter that HTML to remove bad behavior. And usually is one of the first to go--not because it's particularly bad (though getting people to autoload huge videos can be used as a DDoS attack in some instances) but because these filters are usually whitelist-based, and haven't been updated since became a thing.

Do note that the effect is much stronger (at least for me) if the moving object goes outside of the perceived image bounding box - the http://bit.ly/1bUkBJQ example in the original article.

Drawing outside the panel is a standard method in comics when you want to add extra impact or a 3d effect to a panel.

For example: http://siguealconejoblanco.es/comics/wp-content/uploads/2013...

I think this would work without the bars, by just having the object pop out from the boundary box.

Yes, but the white bars give you an (imaginary) non-box boundary that doesn't cost any vertical space, and lets the 3-D effect appear in the middle of the frame, instead off sides/top/bottom

TIL There is a subreddit for this. http://www.reddit.com/r/bubbling .

Well, that's a pretty weird subreddit. Lots of people on there trying to get their "friends" bubbled, probably without most of these "friends" being any the wiser...
