The animation “A Passing Shower” aims at realistic visual simulation of outdoor scenes. In order to render photorealistic images such as wet road surfaces, solar penumbra, streaks of light, etc. the following novel techniques are employed:
• A procedural bump mapping technique for modeling road surfaces and reflection model for rendering wet road surfaces and puddles.
• A shadow model with penumbra effects taking into account the size of the sun.
• A diffraction model of the pupil and eyelashes for rendering blooming effect and streaks of light. (Eihachiro Nakamae)
