Painting interface

This figure shows the different steps necessary to design a "debauched smile" expression. The expressions used through the design are shown on the left (with the area used highlighted). First, we start with a "neutral" expression as our oirginal canvas. We then select a "smile" expression to paint a smile on the lips. In order to raise the left eyebrow, we add a "surprise" expression on the eyebrow. Finally, to lower the eyelids, we add a bit of a "sleepy" expression on the eyelids.
