A 3D portrait

by Valery » Thu Oct 11, 2007 10:10 pm

My first "outer" panorama. I saw beer jugs done with similar technique. Here is the face. One similar photo I met in the Net yesterday pushed me to try my hand myself. Valerij

Hi Valerij,

Interesting work on reality distortion, except maybe squint in her left eye, when panorama users are trying to show reality world in a pleasant view without ugly distortion.

I love that, because it shows something, that we are not familiar to see, as a new kind of picture…
Not a plugin effect… a new kind of the world's view :-)

Beside me good idea

This will be a success for 3D animators, for 3D human model on reality texture...

tell about technology...

GREAT! :cool:

I have a Photoshop plugin which is named "Cybermesh" and which generates a cylindrical or spherical objekts from such an image, when it´s converted into greyscale. It generates altitudes from grayscale. In Maya or Cinema4D you can apply a texture.

Maybe i can find it . .

p.s.: how did you capture it?

@Valery, that's interesting to try some portrait work.

Did you take the pictures from the person on a rotating chair, like an object pano?

Hi guys

As I said it was my first attempt. I had no rotating stool or even a tripod. I took a series of shots, then cropped as you can see in a contact sheet. Then used APP (what else?). Smartblend. Nikon D200, Nikkor 18-70. ISO 200, I asked the model to look ehad. Now I think the best way is to look at the lens.
I've tried to map a sphere in 3DS Max with that weird portrait. No good. Maybe a sphere is too simple an object. I'll look for a head model and then try to map it.

Here is the link to a portrait that inspired me to my experimenting - http://www.photosight.ru/photo.php?photoid=1407520

Very interesting approach Valery, thanks for this new APP tip :)

BTW: how does feel the model… Her image is quite modified?

It's funny to play with this image.
Printing something like this in black and white on format of 60x80 cm should achive a good effect.

That is too cool. APP does cubism. Is this how Picasso got started?
The idea of wrapping the stitched image around a sphere, cylinder, etc seems to get at GURL's suggestion to think about creating a set of projection parameters allowing users to create all kinds of different projections.

Hi All,

\I've been having similar problems to Tony H with this technique.
can anyone give me a quick run through on how to get a nice face unwrap?

Hi guys!

The problem with Tony's attempt as I see it is lies in the abundance of background. If you look up at my post - I cropped the face images so as to elliminate the outer space.

So here are my tips on making a "face panorama" - try to turn the head 15-30 degrees. Then crop the images, delete all background, make them vertical, leave enough overlap for the soft to be happy and I hope you'll succeed


By the way, our faces are assimetrycal. In an "unwrap" it does not look good (but it's natural). I love the simmetrical view, so I copy one of the face halves and glue the two halves together in PS. For the result look at the attachments

Hi,

The cropping does improve things but still need lots of manual work. I'll spend a bit more time at the shoot stage rather than just quick snaps and see how I go.

Did you get the above results by automatic stitching or did you have to put in control points?

Very interesting technic... The last pano is outstanding !!!

I think that team KOLOR will be very interested by that. For SFX movies... Compound with a laser 3D measure, that can make it possible to have a perfect 3D model (shape and texture)
Look. There's a rhythmic ceremonial ritual coming up !

As much the first subject is interesting, as much the second one is quite unfair :rolleyes: :rolleyes:

unfair ??? qu'entends tu par la Beeloba ? unfair = Injuste ??? Je ne saisis pas ta phrase...
Moi je trouve que le second pano est vraiment terrible... bien plus précis que le 1er, le grain de peau est incroyable... j'imagine les jeux ou des films en image de synthèse avec une telle texture...

Je pense qu'il veut dire que le deuxième ne met pas trop en valeur la personne?

En tout cas, c'est vraiment impressionant o_O

No worry vsPiotr, they just understood what I meant… I said unfair because the subject was not aware of what he was going to become on the final picture… This is quite unfair… In french 'injuste' means not fair for him… Is that ok for you :)
Be aware that in the 'galerie' all languages can be used… there is no language barrier there :rolleyes: :rolleyes: :rolleyes:

Thanks Beeloba :)
That is unfair... this is just like when I did a 3d scan of my girlfriends head... with a little too much detail.
And yes, this is why I was interested in this post in the first place. I work in 3d and this would be an ideal way of capturing textures of the face. Combined with a 3D scan you can make things look quite real... have a look at the work on www.zbrushcentral.com for some examples of there 3d faces are at.
It would be great to see Autopano explore this workflow more as well.

..and I hope my comment was not taken too seriously, I have no problems with people speaking which ever language they like :)

cheers!

Take it easy guys. The second "subject" knew what was going on and he liked the portrait all right. It's probably on his walls now. Valerij
