| 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. |
