视景仿真中实体云的建模与渲染技术

Cloud Modeling and Real Time Render Research

在视景仿真中对云的建模和实时渲染是一项十分重要的工作。全面研究了视景仿真中3维实体云的建模与绘制技术,并根据视景仿真对云景仿真的需求,采用分形技术和粒子系统技术实现了一种既能获得良好的视觉效果,又能实时绘制的实体云建模与仿真技术。通过视点相关技术、层次细节技术、动态视点替用等技术大大提高了实体云仿真的实时性,使其在一般的微机平台上可以流畅运行。

It is a difficult task to do cloud modeling and real time render in virtual scene simulation. Most 3D modeling systems are hard to use. So we carryed out a simple real time modeling arithmetic. At first, using similitude arithmetic created cloud particles data. Then, we implemented real time rendering by particle system. Finally, at the process of rendering we predigested the arithmetic and made it be run on common PC.
