Design and implementation of an animation system using deductive object-oriented programming

In recent years, computer animation systems are used for many purposes such as computer aided instruction (CAI) and presentation. In conventional animation development systems, though developers of such animations are usually not experts on computer hardware/software systems, they are required to have a high capability to describe program codes, and therefore it is not easy for them to create attractive contents. In order to support easy animation development, we consider that it is important to separate scenarios from programs. Based on this observation we have designed and implemented an animation development system where scenarios are described separately from programs and managed in a knowledge-base system. In this system, scenarios described in a natural language are converted into schedule data for an animation using an inference engine included in the knowledge-base system, and consequently users can develop animations easily
