|A template image is the color scheme which observed
the continuity on the surface of a head. This color scheme is effective
for discernment from a XYZ axis. The division of the color is not
muscle, but it puts emphasis on the flow (edge ring) of the polygon.
When a beginner recognizes a form, this thinks that it is easy.
The proportion of head is based on Andrew
documents and archives
of Loomis's books.
