The Evolution of the Face Map: Part 2, 3d Puzzles, A WIP


Where were we... oh yes. I finished up the stupid flat way of seeing things and moved on to bigger and better things.

It's like this, when I want to draw a face, I have to make the picture in my head before I draw it. I used to do this by lining up two dimensional shapes like tan-grams, but now it's like building models out of foam.

I start by making a kind of contour drawing of the forms I know and how they fit together on that face: a map.

The shapes that I mark out are fairly consistent, and only getting more so as I practice.

They bear a resemblance to the points marked out by facial research groups.

Have you ever looked at the faces made by those programs? They're often hideous and make no sense. I think their models neglect the third dimension and facial structure. (You all know giving people creepily tiny chins is more attractive, right?)

I have a bad habit, starting with that dumb circle. I don't like circles, they don't leave any lines on the page to help me with depth of field. I like boxes and intersecting lines much better.

I tend to mark in the forhead or brow line next these days. From there is easier to sketch in the trapezoidal prism of the bridge of the nose.

I know I should be putting that curved line that shows the center of the face first, but I never think of it until I've already failed at the nose a couple times.

The base of the chin has to come next.

Next is the marking out of the cheeks and eyebags.
Depending on the day, I might mark the top, crest, or bottom of the cheekbones. I haven't figured out which is the most useful yet. As long as I remember which one I'm marking, it's all good.

Especially on the right side, hopefully you can see some fancy parallel curves (wow, I thought I made that up) happening.

Recognizing curves that are parallel, or the amount by which they are not parallel helps define form.

It's one of those things you have to practice.

Here, the line-age is about to get complicated, so let's turn Chris into a mexican wrestler so you can see what I'm doing.

If you've got a good eye, you can see the shapes I've got below the nose don't quite fit together right below the nose.
If you've got a poor eye, I'll just tell you. I have trouble lining things up below the nose.

List! Everything I just marked out up there:

- The dome of the forehead is marked in pink, and the temples in yellow

- Nose-turning-into-forehead-triangley-bit, in yellow

- Two halfs of the eye socket in purple and green, with that little triangle bit I like so much (discussed already Here)

- Sides of the face, under the cheekbone, in green.

- Third eyebag shown in pink.

- Nasal labial folds in green.

- Boney nose bridge in green.

- Ball of nose in blue.

- Mouth cone in pink.

- Upper lip planes in green and pink.

- Lumpy bits that make up the lower lip, in blue.

- Chin ball in green.

It's a work in progress.
