Light Field Scattering in Participating Media

In this paper, we propose a representation of the light scattering in participating media, which can represent all order light scattering simply. To achieve the model, we focus on the light field in the participating media, and it is shown that the convolution of the light field can describe the attenuation of the light rays and scattering of them. By analyzing the convolution kernel, we derive a simple kernel that represents all order light scattering. Also, we introduce the estimation method of the characteristics of the participating media based on our proposed model. Several experimental results show that our proposed model can describe light scattering more appropriately than existing models.
