建筑物内部火场的模拟显示

Rendering of Fire Field in the Building

主要讨论了三维数据场,在计算机上生成建筑物内部火场的仿真动画。采用基于移动立方体算法,综合运用离散数据网格化、面片简化、表面平滑化等三维可视化的相关技术,使用OpenGL基本函数编程技术设计火场模拟显示系统的具体过程。通过火场模拟系统,读取基于火灾模拟的流体计算后得到的数据场值,可以直观的观察建筑物内火的发生和蔓延的情况,为科学火灾事故研究和虚拟现实研究提供了一个快速有效的可视化分析方法。

This thesis mainly discussed how to generate the computer simulation of fire animation in buildings based on 3D Data Field. It detailedly introduced the entire exploitation process of simulation rendering system for the fire field using OpenGL based on Marching Cubes, the discrete data gridding, mesh short cutting and surface smoothing. The three - dimensional fire visualization browse system, based on the data field of fire simulation fluid calculation, can directly reveal the occurrence and spread of fire in buildings, thus providing a fast and effective visual analysis method for the scientific research and virtual reality.
