海上溢油可视化信息系统的设计与实现

Design and Implementation of Oil-spill Visual Information System on Coastal Waters and Sea

对海上溢油运动规律进行了深入研究,综合运用虚拟现实、海洋GIS及其碰撞检测等技术,设计并开发了一个具有高度沉浸感的近海海域海上溢油可视化信息系统。为了解决当前相关研究中存在的物理模型不完善、模拟效果差及功能缺失等问题,综合了几种权威物理模型,并采用粒子系统、GPU图形渲染和ColDet碰撞检测等方法进行了系统功能设计。测试表明,系统能较好地满足用户操作实时性、交互性和高度沉浸感的需求。

To have an in-depth research on the movement rules of oil spill,synthetically using virtual reality,marine GIS and collision detection,an interactive oil spill visual GIS system on coastal waters and sea was designed.At present,there still exist many defects in physical model,simulation effect and system functions aspect.In view of the current situation,critical technologies such as particle system,3D oil spill model,collision detection on ColDet libs were studied.It was proved that the system can to some extend simulate offshore oil leakage process and met users' request on real-time and interactive operation.
