EXAMPLE OF TYPICAL TOPOLOGICAL LAYOUT

As a comparison to my previous images uploaded, here is a a selection of the same topological layout but morphed to create emotion and expression. As you can see lines in the grid represent the basic structure of the muscles seen in my last post. A brilliant example of how helpful facial topology is when its come to 3D modeling and animation.

MORE IN DETAIL

Here is that same image again but with all the muscles labelled.

EXAMPLE OF MUSCLE STRUCTURE

Here is the basic muscular structure of the face. This is what all topological layouts are based on. Some may vary in structure, simply because of limitation or certain character traits which require specific type of layouts.

MATHS? I THOUGHT ID LEFT THAT IN COLLEGE!?

I found this short explanation on how facial topology mediates the decoding of facial expression.

It took me a couple of read throughs to completely understand it (still don't completely understand it, perhaps going slightly too mathematical)

Intro

Topology is a major area of mathematics. Mapping out spacial properties that are preserved under continuous stretching, squashing and general deformation without breaking or tearing the topological layout.

Applying this to 3D modeling of a head, allows for an easier more natural manipulation of facial expression and emotion. This can also be very handy when following the 3D model up with animation.

I am going to use this blog to show you the development of topological 3D mapping through common debates about techniques and studying solid sources (Of course Im gonna try and not make it sound as boring as that) Enjoy :)
