Prediction Technique of Drifting Course of Disabled Ships;

遇难船舶漂流轨迹预测技术

This paper investigate the application of virtual reality technology to build a aircraft accident simulation system,and provide a method of how to set up a interactive virtual environment,also calculate the condition when aircraft accident happened on the basis of realistic data.

提出了虚拟现实技术在海上飞机遇难模拟过程中的应用方法,给出了建立一个交互式的虚拟环境的方法。

The life and death dimension constructed by victims and survivals is the key of post-quake reconstruction planning and design.

遇难者和幸存者所构成的生死向度是引导空间重建规划和设计的关键。
