After a few quick image searches of chernoff faces, I found that most of them were very cartooned and perhaps unrealistic in their varied aspects. That’s fine, now I just need to create my own crude cartoon sketches.
I began with the head shape knowing that I needed something other than an ellipse. After some trial and much error I was able to create a crude but not obscene outline using an origin point at the top of the head and relating my variables to it. This allowed me to vary the height and width of the face at multiple points without potential of misalignment.
Facial features were created in the same way, with reference to the origin point. variable domains were tweaked so that there was no possibility of them intersecting or being placed outside the face. *I found it helpful to allow the function to loop during this, so that I could see all possible outcomes of the line.*
I now have a legion of slightly critical chernoff faces.
