[whatwg] Dealing with Stereoscopic displays

2010-04-26 Thread Eoin Kilfeather
Hello, I was wondering if any though had been given to a consistant way of dealing with stereoscopic displays. A use case has come up in a project I am working on which calls for the use of stereoscopic UIs but I can find no metion of the term in either the specs or the mailing list archive. My

Rather that trying to make DOM collections feel like arrays, how about just giving them a toArray() method?  This makes it clear that a collection is not an array, but clearly defines a way to obtain an array.  Clever implementors might even be able to optimize common uses-cases using some

What is the implication of denying dynamic changes to the HTMLCollection in a CORS environment? In some variant of Comet (or asynchronous UA polling), how can the UA implement change if it is regularly processing inside locked control blocks? Please pardon my ignorance of the details.

I think it's interesting to think about what browsers could do with stereo output. We already have three features that could produce useful stereo output today: 1) WebGL 2) CSS 3D Transforms 3) video (assuming there was some kind of 3D video format defined elsewhere) What are the use cases for

I agree that this probably means that web elements that are 'flat' would be styled by CSS with a depth. This is important if other material presented to the user really is stereo (e.g. a left/right eye coded movie). The movie will be set so that the eyes are expected to have a certain
