This does not change your point at all, but I did a double take at "years later" and had to check for myself. It was released in September of last year, so less than 14 months ago.

Which part? For the main lighting technique, most of the magic comes from the artist providing the surface normal components. Then to produce the image under some specified lighting direction, you can do the normal 3D graphics thing: dot

Yes, so then the hard part is actually getting a photo of a completely un-shaded object. Alternatively, you could draw the lighting profiles and then specify the true lighting direction for the given photograph -- this is potentially enoug

Yes! Same goes for pulling eigenvectors out of a data set e.g. for PCA (Principal Components Analysis) -- those form an orthonormal basis. You can even pick a set of random orthogonal vectors of the same number and dimension as your origina

For those wondering why the introduction is so long, I'm betting they realize that the opening Cyan logo animation and music instantly transports many people back to firing up Myst for the first time 20 years ago with a nearly identica

I also thought you were saying that this project was an actual implementation of Myst's fictional art of writing ages (as practiced by Atrus), as in you describe something with text and an interactive 3D world is generated that corresp

I love BioShock and I desperately want modern games to be as immersive as Riven, but this example image illustrates why it's often obvious that I'm in a flimsy world made of huge polygons (the tracks in the sky) and repeated flat

Higher quality render of that first Riven image: http://img7.hostingpics.net/pics/104111.jpg More (low-res) examples from Riven in 1997 that I agree still beat modern realtime environments in many ways: http:/&#x

Interesting. Myst was a defining part of my childhood and I reluctantly put up with the shooting and fighting elements of BioShock, Assassin's Creed, Red Dead Redemption, and Mass Effect just so that I can experience and explore the wo

Very true, and I'm glad that approach is being actively pursued by meta ( http://www.kickstarter.com/projects/551975293/meta-the-most-... ). I also like the Oculus Rift hack that Occipital showed briefly here -

So this is a topic I have thought about for awhile -- I released a 3D scanning app for iPhone nearly 3 years ago (uses the screen as the light source for scanning, called Trimensional) and have had many conversations about when Kinect-style

In fact, the animatronic 1964 GE pavillion show that Asimov is talking about can still be seen today at Disney World. It's called the Carousel of Progress, kind of tucked away behind the Buzz Lightyear ride in tomorrowland and sadly (b

Also from Atlanta here and I'm always most aware of this when riding MARTA to the airport. Once you get south of downtown, it becomes hard to ignore the strange fact that the only white people still on the train are those with luggage.

Note that one could also do "area mapping" with nearest neighbor instead of 4-pixel interpolation (if speed is more important than smoothness) to avoid the white dots. This is the most obvious "naive" approach to me -- b

This is a very person-centered view of the universe, no? We're made of the same fundamental particles as everything else, no need to make special cases for when perception and cognition arise in the universe -- they/we follow the

That's great, both conceptually and from an ease-of-implementation perspective. Somehow I've never encountered that work, thanks for pointing it out!

Yes, though there is confusion in the second paragraph of that reply about what it means for the image to be a "matrix". It's being a matrix has no bearing on converting it to grayscale or sepia. It may as well be an unorder

It's a strange post because nobody answers the question posed by the asker who is clearly a complete beginner, wondering how images get converted to grayscale and sepia -- I think it's a much more basic question than the answers i

Thanks for this context -- these were all new to me.

I do completely realize this, but if that's truly the only barrier then we're left in the interesting position in which we can increase society's freedom of communication by increasing energy efficiency. Or maybe then someone

This is completely outside my areas of expertise, and there may already be a name for it, or it may be the dumb thing every rookie thinks of, but what about this: ignoring issues of bandwidth and power consumption (!), if every communicatio

I use POP because of inertia: When I first set up a Gmail account in 2004, I tried IMAP and it behaved in unexpected ways when organizing mail locally with my other POP accounts, so I switched it to POP and have never really had a reason to

I'm not involved with the app, but there's no need for a hidden marker in this case -- the page IS the marker. It is a planar surface with one of a few known black and white images on it. So: Detect features in each blank drawin

"...more and more people are dropping cable..." Exactly -- this is why it was baffling that they spent half the intro event showing features that only work with a separate cable box hooked up to the Xbox, so that you control your

Nope. All photos (and screenshots) are added to iPhoto automatically as long as iPhoto is actually running, even if the iPhone is on wifi in a different country, meaning its not just a local sync. Only videos require physical cable.

by GrantS 13y ago
It sounds like you (and possibly the author of the article) turned off the iPhoto option to automatically import photo stream images to your library. See: http://support.apple.com/kb/PH2712 Other than videos not being included (yes, that'

If anyone is attempting to build something like this, I'll just note that automating this process (spatio-temporally registering photographs and reconstructing 3D models of cities as they change over time) was essentially the topic of my Ph
