This could be handy in replacing video game 3D modellers

Oh, that is nice. I remember the Bach...It was chosen particularly, I think because it is baroque, and it elicits a very specific state...it was commissioned for that very reason. A better choice of music might have been Mozart "Sonata for Two Pianos in D", I think?

Well, when do we get it?

If only The problems here are a) though 3d since they are made from 1 image they are really kinda 1 sided models, if you notice they never go around the backside. b) how many polys are those models? a competant modeller can eliminate unneeded polys for better performance, can this? Still I would not mind having that on the old pc here.

Didn't we *just* discuss this like a month or two ago?

Anyway, sounds really cool. Would be nice to be able to make games without any help

Technology isn't new, in-fact most have been using stuff like this for a while. I doubt it'll ever replace 3D modellers though, best once on the market right now is SketchUp 3D

SketchUp 3D is different. Isn't that the one where you draw shapes and it converts it to 3D? A 2D to 3D convertor is 1000x times more complicated, and there's no way it will ever be able to model the back of objects.

Well, there are 2D - 3D apps like the one that cane as a demo with 3D world, which requires more than one image and does it that way, so you have all sides, their example didn't look too bad, I got as far as installing it, opening it...then uninstalling it, never actually did anything with it, if I can find the disk I might tempted to install it again.

That's pretty cool

In the future we should be able to take 3D photographs

CAT Scanners are basically 3D cameras aren't they? Surely the principle could be expanded for everyday items too.

Clever stuff. At a guess it probably analyses patterns on the flat surfaces to work out perspective and direction. It seemed to do a good job with roads and walls with directional markings and consistent architectual lines, and then fail on the folliages and people etc. I'd guess it wouldnt work at all with a natural landscape, but you can't deny its clever.

Initially, i thought it looked quite cool. But the last image extraction shows it's extreme limitations. I think it uses the convergence of lines in the photo to match the perspective. Thats the clever bit. Humans still get better results.

It would be really handy for making false backdrops to videos/film if the camera was only moving slightly.
