Title The development of visualization software for dynamic data in space launch
Abstract
Visual Simulation，also named as virtual simulation，is an important part of the computer simulation technology. In order to make the space launch own the practical significance of the modernization, digitization and so on, visual simulation is applied to the monitoring and the security guarantee of space launch. A specific launching site is the realistic research object of this thesis. It aimed at establishing a digitized three-dimensional virtual launching space,to realize the three-dimensional simulation of the space launching. This thesis gives the demand analysis of the software, and the research status of visualization technology in every field. It also gives the advantages of using three-dimensional rendering engine OSG to develop visualization, and how to use the Speedtree to make the scene more realistic. Through the establishment of scene models, plus the flexibility of browsing mode, users can intuitively browse the launch site and launch process, because the state of the launching site can be reflected dynamically and truly, so the management of the launching site may be more effecient.
