Types of Animation Control Systems Types of Animation Systems Scripting Systems Scripting Systems were the earliest type of motion control systems. The animator writes a script in the animation language. Thus, the user must learn this language and the system is not interactive. ASAS introduced the concept of an actor, i.e., a complex object which has its own animation rules. For example, in animating a bicycle, the wheels will rotate in their own coordinate system and the animator doesn't have to worry about this detail.
Actors can communicate with other actors be sending messages and so can synchronize their movements.
This is similar to the behavior of objects in object-oriented languages. Procedural Animation Procedures are used that define movement over time. This technique allows an object to change its shape during the animation. There are three subcategories to this. The first is the animation of articulated objects, i.e., complex objects composed of connected rigid segments.
