Hi,

How can we create a 3D Mesh from a 2D region drawn by a user from an Image?

Few interesting Links i found on net...

Please discuss the concepts here!!

Thanx!!

There are different methods for generating 3d maps from 2d data. The first and easiest is to use stereoscopic data, a method that compares two images in order to generate a depth field, which in turn can be used to make a 3d mesh

More complicated methods involve overlaying many basic shapes over the image and picking out models that best suit the image.

There are also software packages that can take video data and estimate the position of the camera. I'm not too sure about the details, but this data could also be used to generate a depth field

I think stereoscopy in the way to go

But have a look at OpenCV it's really good and might be some use

I would personally prefer a height map to extrude bits of the mesh, like in blender!

I also came around something called as anaglyphs. How anaglyphs can be helpful in this case?
