Design A Universal Soft Ware Frame Work Of Visual Simulation For Space Craft Flight

Visualization of Space Mission is a hot topic in AeroSpace Simulation.Based on our Research Team's experience in Visual Simulation of Space Mission for more than twenty years,this paper researches how to design and implement a universal framework for Visual Simulation of SpaceCraft Fligth.Focused on implementation of its universality and extendability,we are trying to make use of it in our daily practice after every changes.After analysing and researching into related topics at home and abroad,this paper uses several methods below in steps in our practice:Firstly,introduce several mature software engineering technologies which will be or have been used in framework in short,analysize some software platform deeply which is used in our development with these technologies from software engineering's pointview.These technologies are very usefull in our implementation.Secondly,introduce some key knowledges related to Visualization of SpaceCraft Fligth in AeroSpace,use Object-Oriented Modeling technology to model the process of SpaceCraft Fligth,present a special domain model.Thirdly,present shortages in our framework and challenges to it,propose several strategies to refactor it and present several principles in designing our universal framework,design a completely new architechture or framework with architechture style and multithread method.Finally,study its realization in several important aspects in detail with these mature and suited software engineering technologies,show a new advanced design.Especially,take visual of physical field for example to demonstrate the framework's universality and extendability.
