油库地面油罐消防虚拟现实系统的研究

Research of VR System for Fire Fighting on Field Oil - tank

主要研究地面油罐消防场景可视化在微机上的实现.介绍了虚拟现实系统开发平台的选择;研究了虚拟现实系统中高级建模技术:通过编程实现3DS三维模型在OpenGL中的调用;利用Billboard技术增强了图形的真实感;运用粒子系统建模技术,实现了场景中火焰、烟、消防水束的绘制.最后,给出了捕捉的不同角度的两帧灭火场景效果图.

In this paper , the fire - fighting visualization of a oil - tank is studied , hardwares and softwares appropriate to VR system are discussed and effective modeling methods such as 3DS - file - loading modeh'ng and Billboard technology are introduced. By taking advantage of particle system modeling methods, a real - time scene of flame, smoke and jetting water is realized. As a result , two frames of realistic images are illustrated.
