1) Storyboard Sketch - This is a black and
white, hand-drawn storyboard of the shot.

2) Layout and Animation - Layout helps the
director plan the location and motion of the camera, and the
timing of each shot. Using models rigged by the Character
Team, Animators can then control every aspect of the character
motion, providing the physical acting for the scene. High-level
controls such as those illustrated here control everything
from what the character is touching to bend and squash-and-stretch
of specific bones. Pixar's proprietary software allows the
final position of the character skin to be seen by the animators
in real-time, despite the sophisticated understructure of
fat, muscle and bone.

3) Modeling, Set Dressing and Final Layout
- The process of modeling involves construction of the virtual
surfaces that define the form of particular objects and environments.
Hundreds or sometimes thousands of these models are then positioned
to form the set and its surroundings. The placement of models
helps to promote the purpose of a shot, leading the eye, or
allowing the character to interact with their surroundings.

4) Simulation - 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.

5) Shading and Lighting - Before a model
is shaded, it is represented by a non-descript gray appearance.
Shading is the process whereby an object is given color and
a tactile quality that helps us to recognize what material
the object is made from. An important step in shading is determining
how the object reacts to light; how light is absorbed, reflected,
or internally scattered by the form. Once shading is complete,
lighting adds virtual lights to each scene, creating the look
of the final images. Colored filters are used to affect light
and shadow, and atmospheric qualities can further enhance
the mood of the sequence. Finally, physically based optical
effects such as the bloom of light on film, the focal qualities
of the lens, and the blur of moving objects provide the familiar
cinematic cues of reality.
