I was thinking. What if there was a modeling program that took a 2d image from the front and back view and turned them into a 3d model? The 2d images would have to hav shading to show how far away that point is on the camera. Does anyone understand me?

If the 2D image already has 'shading' (or at least anything that's useful), then you've basically already got depth information, so it's not really 2D anymore.

There are quite a few like this, just use Google to find them

That's what I meant by saying "or at least anything that's useful".

Shading with regard to the colour of something is next to useless for determining depth in a 2D image.

I mean having a program taking a 2d image that has been shaded to give depth and translating that into the front view of a 3d model.

No computers aren't that good, yet. I once saw a video of an application where you could load a video and model to that, the application then estimates the depth of each of the points you make and you can correct it as the video plays, quite an impressive video but I don't remember the name of it.

I've seen a youtube video of a program made in a research lab in a university where they could turn 2D images into 3D. They scanned in all these photos of buildings and such, and the program figured it out about 50% of the time, but even in 3D it still looked off. It is not nearly perfect yet but they're getting there.

i was at a demonstration at a tech college in Bradford called the WOW academy (nothing to do with world of warcraft) and they had a machine there that could take 6 pics of something (top,bottom,left,right,front,back) and turn it into a 3d model. so i assume it had some software to do it. so i guess it must be possible.


thanks to deathead for the sig! please Click on it!

You could do it with a 3D MRI scan, I suppose.


Since the other one was scaring you guys so much...

Here's an interesting article where researchers are recreating 3D landmarks from around the world using the hundreds of millions of photos on Flickr.

It's a good read

I've seen the demo's on T.E.D. that do the same, but I believe that still is more advanced than what aluseus is asking for:

actually 2 images, one for the front on for the back. I'm not talking about photos, I'm talking about images shaded in a way so that they can be translated into depth.

alus.portbb.com go there.

exactly! Except used to create a 3d model!

That's exactly what a Heightmap does...

'Shaded' is not the word you were looking for. A better one would have been 'Depth Information' because 'shading' implies that the image has other data assosciated with it (ie, an actual image), whereas all the colours in a heightmap go up to make the 3D depth
