However, to create 800 distinct
models, with 800 distinct animations, would not only be an awesomely
onerous task, but would be impossible for the program to handle in
real-time. Our solution has been to define 32 basic audience groups,
for example, one group of upper class WASP men, and another of middle
class African-American women, and to script and animate responses
for each of these groups. We then created from three to five physical
variations for each group (i.e., three to five different faces and
costumes), so that there is a total of approximately 120 different
spectators, each of whom is repeated several times. We produced even
more variation by adding and subtracting hats and facial hair.
