Doing what I forgot to do I looked at muscles in the face and how they move. I tried to find some video on the face moving but turns out theres not many of them (at least of what I could find) The best I could find was the one below however there is very little movement.
Michael Bass shared a website which was very informative about the facial muscles, giving their exact names and their locations.
Looking this and their placement made me think about the placement of poles. In the series of tutorials i’m doing on Digital Tutor, poles are placed in certain areas. Now seeing the facial structure I can see why. They re put in places with no muscles, (mostly) allowing for less deformities.
Thinking of all the edges loops in areas we can see why a lot is needed for the eyes and lips. The Orbicularis Oris Muscle (muscle around lips) and Orbicularis Oculi Muscle are in the areas of where that geometry would be. Orbicularis meaning “a muscle made up of several layers of fibers passing in different directions” – “Medical Definition Of ORBICULARIS ORIS”. Merriam-webster.com. Web. 14 Apr. 2016. We can see why poles and triangles are forming in these areas. I have to say its nice knowing why there is so much trouble with these muscles.
Overall looking at this has helped visualise a lot more of why the geometry in my head model is the way it is.
