I'm amazed and I don't understand how's that even possible. I know that this type of videos don't fit exactly in this category, but I think I posted it in the right place since this kind of technology will help a lot in the retouching process.

Anyway, take a look:

This is CRAZY! I was watching it thinking eh! how! erm!
It would be great for adding extra props to your photos etc.

That is completely mad.  Seriously how is that even possible?!?!?

That's pretty cool! How do I get that program?

I'm imagining that you can use that on a model and pose her anyway you like! big_smile

The profile of objects currently has to be 'regular'; they showed how a tube of toothpaste caused problems.

Going to be a little while before this will be practical for irregular object like people--but it'll probably  be used to help with a lot of product work before then.

This is very interesting, thanks for sharing this video.
Steps look very fast on some simple elements ( where we don't have on file very problematic extractions like fly away hair and problematic transparent fabric/clothes, problematic fur or any problematic transparent objects, where you have to work special color decontamination steps which is the most complex work in retouching) .
On very simple elements for extracting software works fine ( but we can not see on 100% of view extracted edges,  do we have any halo edges on file) .
So I think it is very early to discuss about this future software , until we don't have chance to check software with real files and situations.
You can do all these steps in some other 2d/3d software but you need more time to do job, but with that programs you have full control of edges and shadows , because you control all steps and situation.
I am always reserved with quick steps of extraction because quick steps make too much halo edges on file.

For example we already have on the market some plug-ins for hair extraction and transparent fabric/clothes extraction for composite work but not even one plug-in give professional results , so no one from the industry use that plug-ins for top professional results, because they produce halo edges  in many cases.
Real professional extraction for composite work need highly skilled retoucher and it is very time consuming if you want to produce top realistic results ( without fake digital work with halo edges and non-realistic composite work with fake digital fantasy backgrounds)
On their tutorials you can see "miracles" but in reality it is different story .
In composite work and extraction each file is very unique to work and you have to be highly skilled and very experienced to know which steps you have to use for extraction and composite work in PS.

I can compare Professional extraction with D&B skin retouching.
If you want top beauty retouching there is one and only step--- pixel level D&B, no plug-ins.
It is the same with extraction - pixel level work on edges to avoid any problematic halo edges on file and later special color decontamination process for edges , hair , fur and transparent fabric.

Anyway we will see in the future these things , if this software can make miracles with fly away hair, transparent fabrics/objects ,and everything to be so perfect on 100% of view and with very large prints  they will make revolution in photography business.

But again until we don't see everything perfect which I wrote above with real files and real situations and on 100% of view  , we can not discuss anything.
I am very interesting to see their results with problematic elements for composite work  which I described above .

Best

Copying my post from the General Industry thread on this same subject:

I am sure someone will find some limited practical applications for this, but the problems are rather glaring.  For example, since the original lighting from the photo is mapped directly to the object, as soon as you rotate it, the lighting becomes wrong.

Also, the objects it is capable of doing are just extremely simple extrusions which could be modeled nearly as quickly by anyone competent in using a decent 3-D software app.

Notice the examples of fails at the end of the video.  Just having a misplaced shadow in the image screws up the whole operation.

The technique is cute, but not really new (photogrammetry has been around for a while).  This version seems rather like some grad student's Ph.D thesis project and not ready yet for prime time.

Bravo Peano,
this is great example about shadows , many people don't understand these things.

But also artist Green without a cat has great post about shadows and reflections.

Shadows and reflections sometimes can be so difficult .
For example check this file from web on this link

http://www.google.com/imgres?start=139& … =140&ty=33

As we can see from this link above , here we have nice Jeep captured in the forest where we have very problematic shadows , highlights and reflection from trees and leaves on the car glass.
So we want here to make quick extraction , we want to convert Jeep in 3D model with automatic rendering .
Theoretically we can make that with some software , we can make quick extraction and rendering like it is.
But what about if we want to make composite work with that new 3D Jeep model for example with Sahara background .
At Sahara backgrounds we don't have trees , leaves , just sand and sky.
So which automatic software will clean trees and leaves shadows and reflections from the car and make automatic 3D Jeep model with  transparent car glass without shadows and reflections from trees and leaves.
We want in Sahara desert new 3D Jeep model with transparent car glass where we can see through car glass sky or sand, we don't want in Sahara desert car with trees and leaves shadows and reflections on the car glass.

So which automatic software can do that, except hours and hours ( or days and days) of highly skilled handmade work in software.

What does appear advantageous, though, is the ability to easily duplicate existing elements and move them/manipulate them in a virtual 3D space.

Even if all the edges require exactly as much clean up as they would without this functionality--as appears likely--the 3D transforms are going to save time and reduce the minimum drawing skill level for that kind of composite.

Nevertheless, it's an interesting proof of concept; actual results will rely on execution in some future tool.
