【摘要】 提出了一种真实感雾的实时绘制新方法,该方法对以刻画光能穿过雾这类参与介质发生的吸收、自发射、散射和内散射等光学现象的光能传输方程进行一定的近似,利用余弦函数并通过改变其中的相位参数作为衰减系数实现了非均匀、多层次的静态与动态真实感雾的实时绘制。更多还原

【Abstract】 This paper presents a novel method to render realistic fog in real-time.Based on approximating the light transport equation that describes four interactions,namely,absorption,emission,scattering and in-scattering,between light and fog media,it utilizes cosine function as the extinction function to depict inhomogeneous and multi-layer fog.Also,it extends the new method by modifying phase parameter in cosine function to simulate dynamic fog at a low cost.更多还原
