一种非均匀参与介质的实时光照方法

he real-time rendering of non-homogeneous participating media(e.g. fog) is one important research topic of realistic rendering in current virtual indoor scenes. We present a real-time rendering method of participating media in indoor scenes(e.g. virtual stage). 3D texture is used for organizing of the information of media, and rendering of the non-homogeneous participating media. By combining shadow map, shadow volume and ray marching techniques, a new hybrid method is proposed for rendering of volumetric shadows under participating media. The experimentation indicates that this method can represent illuminating effect and ambience of virtual indoor scenes more realistic, and has real-time attribute.
