'The Incredibles' Progression Artwork
5) Shading and Lighting - After the characters' bodies are animated, the motion of their clothes and hair are added. This motion is based upon the movement of the characters, using a computer simulation of the physics of fabric and hair. The simulation takes into account gravity, weight, stretchiness, friction and other factors, as well as the collisions of each garment against itself and its surroundings. The result provides a very natural looking shape and motion, which can be further augmented with virtual wind, magic clothespins, adjustments to the passage of time and other techniques used to ensure that the hair and clothing move in a manner consistent with the goals of the shot.
