Converting 2d image into 3d 'cloud point'

Hi !

I am searching for solution to convert 2d images into 3d objects.
I've been doing some research and so far most promising solution which I've found was described over here:
http://stackoverflow.com/questions/31322052/turn-any-2d-image-into-3d-printable-sculpture-with-code

What do you think about that approach, do you think it's possible to implement it to use in unity on +/- 10 images in the same realtime ?

How would you start working on this subject ?

Thanks for any advice !

 

At least could use shader to extrude mesh based on the texture (as in heightmap, brighter is higher)..

would look like this:

 

It looks neat, where can I find this shader ?
Thanks !

 

Here's similar shader, using tex2Dlod inside vertex shader to extrude based on heightmap texture,

And use some high resolution mesh plane,

Thank you so much, I will take a look and come back to you if it will be necessary.
