The Research Of Graphics Data Exchange Intelligent System

Nowadays,because the demanding of graphics processing software increased widely,more graphics processing software appear according to different areas,different demands, different performance.Some authoritative graphics software companies develop platform interface actively and find some solutions,though,much of them can't provide interactive interface,why much graphics processing cannot exchange data directly.Even if there are some platform-based development interface and graphics processing software which could exchange data,most of them are dependent on their own understanding of graphic software and supplied for specific user group and application objective.All of these resulted local order but integral disorder in the fields of graphics software.This thesis puts forward an Rule -Based Graphics Data Exchange Intelligent System (RGDEIS ) model according to graphics data exchange method and the significant graphics data exchange standard.This model adopts production system's basic idea,dividing the whole model into three parts:switching control system,transformation rule base and comprehensive database.Transformation rule base is the kernel of the whole intelligent system.It is a set stored all the rules related to graphics data exchange which contains the transformation from source figure data to intermediate graphics data and the intermediate graphics data to object figure data.These rules describe all the knowledge of graphics data exchange during the whole graphics exchange process.According to the analyse of production topology,we decide the structure of RGDEIS model transformation rule based on the idea that relational database represents production rules and realize the exchange regulation during using relational database described data switching.Switching control system is an inference mechanism composed of a group of programs,which controls the running of the whole graphics data exchange intelligent system,decides inference line during switching process and implements the switching process.Meantime,we establish inference mode and conflict resolution principle in switching process combined with graphics data exchange's basic knowledge.This thesis introduces knowledge acquisition in graphics data exchange process and implements a graphics data exchange system based on RGDEIS model at last.
