Human Hand Study - A Deformation Rig Demo

[andreja]

Man, amazing deformation and rigging skill! Also great NURB's patch modeling skill from Armando. Keep it up guys!:thumbsup: I really like this stuff.:applause:

[doffer]

Wow!
That is mad rigging skills.
Never thought about that tracker thing. It looks really nice. Like a on-the-fly skin morph.
Could you really convert that into a full body system? I would think it'll get pretty heavy to work with all that.

[liquidik]

Absolutely wonderful and inspiring. Two questions come to mind right now:

- why nurbs? It this some sort of limitation or is it used only for the high res geo ?
- how does this system scale to a full character with facial and everything else ?

Anyway, I think this is how a TD reel should look like. I'm pretty much bored of seeing videos that move the LFootIK, LFootFk, Switch to IK, blah blah blah

Much respect. I'm always trying to ignore the insane complexity of the human hand... you acknowledge and revel in it!

[wamo]

Hey Igor!
it's just Awesome!i realy love it , it is complatly inspirable for me!

[Glacierise]

That's absolutely incredible!

[HEKTOR]

Yeah! It's great! Congratulations, very nice rig, and model too!

Greetings!

[Helgi]

I second that that this is absolutely amazing, so much control and really good deformations... and it's almost all procedural which is fantastic.

I also want to know, what liquidik asked, can you apply the same method to a full character and facial rigs?

[caniky]

Very nice and detailed rig. Great deformations too!

Looking forward to see more! :thumbsup:

5 stars

[MikeRhone]

Very nice stuff. I don't think I've ever seen anything like this for hand rigging. Impressive!

[Sova]

Great work mate. :) We have the same name heh. Were are you from actualy?

[Winner]

I love the way you implemented this.... great deformations, and very artist friendly setup by the looks of it.

[bakicv]

Great work, can't wait to see the full body and face rigs!
I salute thee :)

Hi guys,
Thanks for all the comments!

Hi doffer
Entire system with deformation joints and trackers is designed for easy corrections and tweaking. Once deformations are final, it's possible to bake everything procedurally into pose-driven corrective blendshapes, and keep just basic animation joints with these blendshapes on top.

- why nurbs? It this some sort of limitation or is it used only for the high res geo ?
- how does this system scale to a full character with facial and everything else ?

to liquidik
Armando Sepulveda, my friend who modeled the hand, wanted to do it in nurbs as a modeling challenge; so in the end it stayed as patch modeling but could also be converted to polygons;
When full body and face rigs are added, some optimization methods like I mentioned above would be very useful. Basically, it gets heavy in the end when the final model gets connected to everything.

[Pisellino]

Amazing ! Congrats...

How the system works ? is completely automatic ?
How many joints are there ?

Cheers.:thumbsup:

[Orlando]

Best hand rigg I saw so far. 5*

[rustbucket]

Good lord. Thats what I call control. Really amazing work!

[BartokDesign]

wow , very impressive. great deformations.
:drool:

[sgbox]

thats great man. very very very good work.

[borajurisic]

5 stars excellent!!!

[tiektieco]

Hi Igor,
I like this system!
It seems familiar for me, but it's still very good, 5 stars here too.. ;)

[zzhAgain]

It's vrey nice!

[IgorStefanovic]

Hey guys,
Thanks for all the comments :)

tiektieco,
All the best with your new job in Rome!

[rasmusW]

hehehe.. you just got 5-6 geeks drooling. nice job man.

[d-brooks]

Hey tiektieco and Igor,

great work Igor, hope you are both well :D

Actually Igor, a question?

How are the joints distributed? Is it using the weighting of the anim joints? Just curious.

Hey Dave,

What's new!? How is your London life these days? :)

Basically there are regular animation joints, which are animated; and deformation joints which are parented to animation joints and they translate depending on rotation of animation joints, to simulate skin sliding and bulging. You can see animation and deformation joints somewhere in the first third of the demo reel. So the skin is assigned just to the deformation joints, and there are pretty much as many deformation joints as there are vertices in the geometry.

[d-brooks]

Thats great Igor! What caught my eye was the way some of the deformation joints are positioned along the tendons in the hand. Were these joints placed strategically?

Yeah working in London is good! I'm freelancing for a spell, soon to move elsewhere. Start a new job monday. Hows things in the states?? I bet you're having a great time!

[JohnPGiancarlo]

Very good job!
