摘要
随着科学技术的发展以及互联网的广泛应用。使用计算机图形学和虚拟现实技术对不规则物体进行模拟现今已经在国防、气象、网络架构等领域得到了广泛的应用。使用粒子系统对云雾等不规则图形进行模拟可以极大地减小模型3D真实度对计算机配置的需求,降低平台架构难度。同时由于粒子系统建立模型的随机性使得建立的模型具有更加自然的视觉效果,更加合理的物理学结构从而能在广泛的领域得到应用。本文应用粒子系统与纹理过程函数相结合的方法对自然景物中的云雾模型进行模拟,在具体的模型绘制过程中应用纹理映射和Billboard技术来实现,从而提出了一种多种建模方式相结合的模拟不规则物体的全新方法。
With the development of scientific technology and the wide application of the Internet,the simulation for irregular objects with computer graphics and virtual reality technology has been widely applied in the field of defense,meteorology and network architecture.The simulation for irregular objects such as cloud with particle system can greatly reduce the demands of 3D fidelity of model to computer configuration and reduce the difficulty of platform architecture.The randomness of the model constructed by the particle system makes the constructed model have a more natural visual effect,and a more rational physics structure can be applied in a wide range of areas.In this paper,the simulation for the cloud model of natural scenery is made through combining particle system with texture process function.In the concrete model drawing process,the simulation is realized by texture mapping and Billboard technology.Therefore,a new method of simulating irregular objects through the combination of one mode and multiple modes is proposed.
