Fast Generation of 3D City Models
FleaPlus writes "New Scientist and UC Berkeley News report on research by Avideh Zakhor and Christian Früh on rapidly and automatically generating photo-realistic 3D models (coral cache) of city environments. This is reminiscent of research mentioned here in March, although the approach is rather different. Applications for areas like urban planning, entertainment, emergency response, and the military are discussed. Zakhor's group is also working on 4D systems, to allow for recording of events over time as moving 3D models."
The long awaited release of Sim City 5
Because God designed it that way.
Next question.

If I remember correctly... companies like Silicon Graphics have been doing this for several years for the military using their reality center systems to analyze satellite photographs of combat zones in real time.
feeling lonely? grab a balled up pillow for company
This would be awesome for flight sims. If you want to view this in this in Linux here is a viewer.
I can't wait to "get out of the house"!
Now the military can fake invasions in cities while working with the media to control us all. Cool. /removal of tin

Excuse me.. but 'photo realistic' usually means that it is close or completly indiscernable the same as an actual photo of a real city. To be honest I've seen similar things from Sim City 2000 and see no real merit from the 'final product'. Really, how is this new? Sim City? huh? Nevermind!

This technique should be replaced with (or combined with) LIDAR techniques. LIDAR (Light Detecting And Ranging) is like a laser version of radar, and it can be used to generate 3D maps of objects or topography fairly quickly. A LIDAR-enabled plane can do a fly-over of a city and quickly generate 3D maps. For instance, check out these LIDAR images of New York pre and post 9/11.
I've always thought that these 3D maps of cities should be combined with satellite imagery so that you could 'paint' the rooftops onto the buildings and streets. In fact, most satellite images are at a slight angle, allowing you to paint the facades of buildings. The techniques from TFA show how you could paint even more facades in the 3D model/map fairly easily. I think the LIDAR data would greatly simplify the painting algorithm, since the correct 3D shape of every object is known.
I can't wait for the day when we can browse 3D maps online of any city. It would be useful for surveyors and architects of course, but also useful for planning trips, learning geography, and so on.
For instance Picasso (in his early days) did paintings of peoples faces from different angles and with different emotions all as one face.
This is my last post.

Where are the crackwhores, pimps and junkies?
Is some big backbone route in the USA broken or is it some kind of a holiday? I hope you're not saying that people are actually spending a Saturday night out, for chrissake!
finally live action 3d pr0n!!!!!!!!!!!!!!!!!
It's a bit-torrent link and please remember kids: only pirates resort to P2P. You wouldn't steal a car, you wouldn't steal a purse, you wouldn't steal a movie. It's that simple.
AKA a nazi fanatic loser.
....
...etc.
1. You rejuvenate and dance when you hear a windows flaw exposed, but you conveniently ignore the thousands of security flaws exposed in linux.
2. You yell loudly TROLL! at any person's post or at any person you see posting facts that you do not want to hear about your oh so cool linux.
3. You know it's a classic case of penis envy, you don't have all the support, software and hardware available for linux and you have to let that anger out somewhere, but you don't have the brains to admit it.
4. You hate windows, hate Microsoft, but race to emulate windows, have programs to run office from within linux, and spend a $300 on a Windows emulator, only Windows fools.
5. You cannot admit that you don't have professional usage of Linux outside server markets.
6. You cannot admit that most of the joe user out there when told that there is linux will respond, what is that?
7. You cannot admit that there is no professional printing capabilities in linux.
8. You cannot admit that you are a masochist (otherwise why would someone spend hours playing with scripts,
and recompiling programs that are available for Windows?)
9. You cannot admit that there is no professional desktop publishing done on Linux.
10. You cannot admit that no one in their right mind would do professional video editing in Linux.
11. You cannot admit that linux sucks when it comes for gaming/home entertainment or education.
12. You have problems in understanding Windows, and you will blame your own incompetence on Microsoft.
13. You have problems in pointing a clicking, but have no problems in wading through cryptic scripts written by lunatics.
14. Nothing will get past that shit that fills your head, you will not admit to any facts.
15. You can't admit that naming of linux components, packages, and others are weird and fits profiles of troubled teenagers. gentoo, lgx, rpm
16. You feel angered because you were left out by microsoft's Media technologies, they support Mac, Sun sparc, but not linux.
17. You feel inferior deep inside but unable to admit it, you don't have a database as easy and powerful as Access.
18. You cannot tell that not a single office package outside Microsoft's is worth looking at or bothering with.
19. You don't know that your CD recorder software sucks.
20. You don't have DVD-RAM, DVD-R, DVD-RW support in your pathetic OS.
21. While the rest of the world moves on, you're stuck in a stone age technology that needs third party software to boot into GUI.
22. You act out of prejudice, you kill file domains and users of specific news readers while you ignore the bullshit that your fellow linux losers post.
23. You don't know commercial support in Linux is almost non existent.
24. You miss the fact that companies are leaving linux because of the chaos, and the cheap linux losers who are unwilling to pay and support hard work, Corel, gaming companies,...etc.
25. You are unaware that linux has no terminal services (there is a lame one that no one uses), and commercial support for it is not happening.
26. You are unaware that setting up servers on Windows takes couple of minutes while on linux, good luck playing with configuration scripts.
27. You cannot admit that support for USB on linux is laughable at best.
28. You think that Linux is better because slashdot told you so.
29. You spend countless hours flaming people because they post their opinions about your oh so cool linux and your attitude, instead of researching things for yourself and understanding fact in order not to look this stupid.
30. You think that anyone who uses linux has a clue.
31. You think that linux cannot crash.
32. You think that everyone is interested in your conspiracy theories about Microsoft (or should i say M$ in order for you, teenagers to understand?), and how they destroyed linux,
33. You keep ignoring the fact that thousands of linux servers get hacked every year, but it takes one Windows server hacked to get you and your fellow linux idiots to dance and celebrate.
You, I mean.
Please die. Or at least get one of those "brain" things.
I would really be impressed if they could automatically generate a 3D model of the three dimensional mess that is Lausanne:
...I claim he was just painting angular, childish drawings requiring no particular talent, and then threw some meta-artistic gloss on it.
for example
http://www.geosimcities.com/showroom_Phil.htm They were using laser to scan cityscape too.
It would be great to have this integrated to a GPS or something .. you can polan routes and tell what sort of a neighborhood a restaurant is in etc. I await the day for cameras to be equipped with GPS .. well current camera phones .. they dont write GPS data into the EXIF do they. Anyway .. integrate that tech with location and time etc. and you can have reviews of restuarants and picture or video records of neighborhoods etc. at whatever times. It would be awesome. All at the tap of one's fingers .. google is helping facilitate this with google maps .. now we need a wiki type thing to enable this sort of thing.
The problem with these techniques is there are no algorithms I know of that account for the effect of light/shadows effectively. So the textures on your objects are going to include shadows. You can notice this effect on one of the images that have linked to in the article.

Yahoo has been digitizing the front of buildings in major cities for some time now. It'd be great to see this imagery merged with Google's satellite view data from their KeyHole acquisition, to allow for 3d flythroughs of your favorite metropolitan area.
This could take sites like MapQuest to a new level, providing 3d photo-realistic flythroughs of your route between two locations. Sure beats reading directions!
...I can't think of anything more intelligent to say than "Damn, the next Sim City is going to be AWESOME!"
That and, as a computer animator, I can see this being very useful various CG fields.

Or was it called "4D Studio Max"? It has been a while since I abandoned the world of 4D editing, for good ol' simple 1D (top down yeah?) programming...
take these maps, and put them in a driving game. would love to drive around my city virtually.. and then get stuck in grid lock traffic in the morning ..
Now imagine sending a fleet of probes to Mars consisting of an array of satellites and ground based robots that determine and design everything necessary for perminent human habitation. Imagine taking the initiative and sending such fleets throughout the solar system to all sorts of places we will want a foothold decades before mounting such complex missions. Such a system could red flag all sorts of problems with environments that would have otherwise caused a manned crew to turn around and go home. One step further: Imagine sending (even later in time) more advanced fleets that could study a place and contruct a human habitation with robots and materials before humans even left Earth to head where ever. Even further: now imagine sending such fleets to other star systems centuries before humans. The environment could assesed. Suitable structures built and pressurized with atmosphere. Everything could then be maintained by yet another group of robots for centuries or even millennia with every aspect of the greater system under the direction of planning software. Hell they could mine endless reserves of materials and chemicals that humans would want upon arrival. Alot of this would likely require advanced nanotech.
I am sure it can be taken to even greater extremes.

BTW - I have been visiting slashdot everyday since it opened in what, 96 or 97? As of this post I have only now bothered to create an account! So FIRST POST in a sense I guess.
it's not every day you see posts on slashdot that have giant detailed 3d models of two blocks from your house...
If you dont squint your left or right eye and really really look at it you can kinda see how it resembles... Dali's The Persistence Of Memory painting.
See content acquisition section here.
How easy would it be to take this modeling infomation and to import it into one of our favorite games, such as CounterStrike or CS:Source?
