基于DirectX的云模拟研究

Research on Cloud Simulation Based on DirectX

虚拟场景的逼真动态显示是飞行模拟、实时动态仿真及虚拟现实等技术的基础。在飞行实时仿真系统中,云的模拟效果对于飞行模拟和飞行训练来说是非常重要的。文中介绍了3D图形函数库Direct3D,在分析纹理映射以及粒子系统实现原理的基础上,分别讨论了采用粒子系统建模和应用纹理动画技术来对云进行模拟,实现了真实感较强,渲染速度快的云层效果。文章最后对两种方法实现的云的模拟效果进行了对比,并指出了两种方法的优缺点,对今后的研究有一定的借鉴意义。

Lifelike and dynamic displaying of virtual scene is the basis of flight simulation and real - time dynamic simulation and virtual reality. In the flight simulation system, the effects of cloud simulation are very important to flight simulation and flight training. Introduce Direct3D, and separately discuss simulation to cloud using particle system modeling and texture animation technology on the basis of analyzing the principle of texture mapping and particle system, and realize the cloud which has third dimension and fast rending speed. In the end, contrast the effects of cloud by the two methods, point out the strongpoint and shortcoming of the two methods which has reference meaning to future study.
