> 中文摘要: 提出一种适用于雨雾天气的天空光照的多粒子散射模型,实现了雨雾场景中大气散射效果及雨后彩虹的真实感绘制.同时,通过对传统点光源单散射模型公式的解析简化,实现了各向异性光源散射效果的实时绘制.最终实时绘制出多种不同条件下真实感较强的雨雾场景.
Abstract:This paper proposes a model of skylight and multiple particles under rainy and foggy circumstances and implements real-time rendering of atmospheric scattering in rain and fog scenes and rainbow. In addition, by analyzing the conventional equations of single scattering of point light source, real-time rendering of scattering effect is implemented due to non-isotropic light source. Finally, realistic rain and fog scenes are rendered under different conditions in real time.
