基于中点偏移算法的云的模型设计

Modeling Cloud Based on Midpoint Deflection Algorithm

自然景观的模拟在许多方面得到了应用 ,云是自然界中的一项重要景观 ,对云进行模型设计显得十分重要。针对目前大多数的云的模型设计方法难以在普通 PC机上快速实现真实感较强的云的模型设计的问题 ,提出了一种自然景观中云的模型设计方法。该方法以分形理论为基础 ,设计并实现了一种云的纹理生成算法 ,并采用纹理映射技术 ,绘制云的图像模型 。

Recently, simulation of natural phenomena has been applied in many fields. Clouds play an important role when generating images of scenes, so the simulation of clouds is very important. Given the problem that the most methods can't produce the realistic clouds model quickly in general PC, a method for modeling cloud is proposed. Based on fractal theory, a kind of algorithm implemented to create texture of cloud is designed, together with texture mapping, a cloud model is obtained and the simulated result proves realistic.
