3d information captured from video?

lampekap

Hi,, ok so I recently watched this video: http://vimeo.com/7341615
In the tutorial, the instructor shows how to match 3d geometry to a photo.
somewhere in the beggining, he says that if this were a video, u will be able to use some "super powerful software" to capture of from the video 3d information. Ive never heard of this before, and I don't know the technical terms for this, and I have no idea how this works. If someone is able to explain this I would be very thankful

I saw this a while ago, Blender with a real time displacement modifier. Maybe that's what you are thinking of?

Hey, that's from our own chronic.

You might be interested in PhotoSculpt.

photosculpt seems like a interesting tool, and the real time displacement modifier for blender too. When I heard chronic mention the kind of 3d capturer, I linked it to using for example a 3d model in a movie, where the 3d object turns as the camera moves , as if part of the actual enviroment. Is some kind of capture tool used or do those people animate the camera movement by hand? on chronics portfolio is a movie just like this where a robot marches on top of his desk

If you want the virtual camera matched with recorded footage from a video, there are tools such as MatchMover (now included in Maya, Softimage, etc) to help match the movement.

If it's just a still matte painting projected onto geometry, it shouldn't matter how the virtual camera is moved, as long as the initial placement is matched.

Match moving?

or

Augmented Reality?

note: There are more threads on augmented reality just do a search.

There are a few other options out there too, I couldn't imagine anyone doing it by hand... well I can but they are working on Sci-fi specials like "MEGA NUCLEAR POLARBEAR VS GIANT KILLER ANTZ!"

awesome, I didn't knew it was called match moving.
This is a really cool thing to play with im assuming

There's an (oldish, but free for non-commercial) match mover called voodoo, though for some reason its results are always upside down for me. :P

boujou's got a really good reputation, and is laid out to walk you through everything you need to do. Also tended to give me the better result (compared to MatchMover) when I had to match footage with heavy motion blur.

Just some other options.
