View Full Version : Simple Head in NURBS
11 November 2003, 09:34 PM
Hi, I know that Nurbs heads are out of date but I wished have a try because i've never got success in modeling this way.
Hope to hear some"Focused" critics plz.
note It's still half a head. and the ear is polygon.

Hey - nice start - my only crit at this point would be to consider the proportions of the head - the face in relationship to the top of the head/skull. The face in your model seems a little long, although well modelled, it seems to be to large in proportion to the rest of the head. Just my 2 cents. Good Luck!
here are some links that may help-

thanks, it's really a valuable help cuz I focused on the gemotry and forgot the main shape !!
And this what happen to someone who's not using picture references like me.

I'd suggest reworking the part around the eyes, because you have no edge loops at all there, u have a lot of unneeded lines on the upper lip, the bridge of the nose and on the cheeks.

I agree with the previous crit of working on proportions. Im assuming its going towards photorealism, that is. The major things are the size and place ment of the ear (should be smaller, tilted back slightly, and lowered to the top of the ear is on the same line as the center of the eye) Also the dent of the nose between the eyes is very deep, there should be more struture there, bring it out more, and prehaps make the angle a bit less vertically. Also consider bring the lips and chin back in a bit instead of straight line down from the nose, instead of straight, try a diagonal. On the top lip theres a heavy seem, which should be much more sutle. Hope this helps. Good start.

The problem of proportion is easy, but reworking the distribution of line is a little bit hard.
MoD_Legion, are you sure that nurbs heads could have loops around eyes? I didnt see a lot of them but here is my guide:
Especialy when you're modeling the head in a single piece like mine(beside the ears).
Edit: Forgot to say that this last pictures are from 3drender.com of Jeremy Birn.
And I'm using Maya for Modeling.

I wish to add that the number of isoparms is very logical to me. I've bought a book a long time ago titled " Mastering Maya 2.5" where the authors are showing a way to model a human head in nurbs but they used patches as you could see here in the picture the nose area is detailess. I need to add some vertical isoparms to get the right shape.
For my Head, I worked today on the proportions as suggested and hre is what i've got. Hope he has a better look.

this head is getting better . seems you really like nurbies. check these tuts out :

At the end, I'm still wodenring if it's possible to do this famous edge loop around eyes with a single piece of nurbs head !! All examples seen in the links are about using patchs.
Personaly I dont plan to do anything with this head, it's just an exersice for me because I prefer Polygons/Subdv.
It seems my head is perfect that's why I'm not getting feedbacks !! hehe just kidding :P

hmmm edge loops around eyes have quite important, they help you get a much more realistic shape and keep you deformation neat and realistic, the reason your having trouble I think is because you started with the mouth(I could be wrong) I generally start with one eye and build from that I find this keeps my topology nice and clean, not something you might want to take up but worth a try. If you continue the way you are then try to bend the nose polygons around to form your eye edgeloops. Apart you the topology nice work keep it up and experiment.

All right, thanks.
It seems that Nurbsare really oldies and peoples forgot them at all. All peoples here are building heads with Polygons (an me too with my poly heads)
I started with a Nurbs Sphere then pushed/pulled CVs to get the general shape right. I could convert to Polygon this stage and would be easy to continue with Subdivision or just Smothing, but as I mentioned it's just a challenge for to build th whole head in one piece(beside the ears)
Hope to hear some comments from Nurbs gurus.
