Local and Global Control in Computer Animation
Abstract
In the past few years a lot of effort has been done on modelling computer animation
schemes through physical laws. Indeed, the behavior of almost all characters in
an animation or in a simulation can be represented by mathematical tools, such
as differential calculus. On the other hand, interactions among actors and the
animator suggest some other approach. Following this line of inquiry we split
the computer animation control problem in two parts: a local control problem and
a global control problem. The local control defines the "behavior" of each
character, while the global control is responsible for the interactions. In this
paper we propose an event oriented scheme to solve the control problem. This has
been done using concepts regarding to DEDS (Discrete Event Dynamic System)
and ESM (Extended State Machines).
