Abstract:
We propose a method for rendering realistic three-dimensional raining scene. The proposed method gives two main contributions to rendering raining scene. The first one is to propose a simple model that deals with temporal-spatial localities such as wind effect, density and intensity of rainfall, and raindrop brightness, so as to represent environmental conditions that differs on a scene-to-scene basis. The other one is to propose a raindrop trajectory computing method whose computation load immunes to the number of raindrop, wind effect and complicated camera movement. Due to the above-mentioned contributions, the proposed method can represent essential aspects in raining scene, such as spatial changes of rain in urban canyon or temporal changes due to the moving wisp of rain.
