要約(英語): This paper presents a real-time method that simulates motion of snowflakes on a windshield. A few minutes after snowflakes attach on a windshield, the snowflakes start to slip down. And they reach to the bottom of the windshield, by repeating the sliding and the stopping. During the sliding, snowflakes change motion direction at random. If a snowflake hits another, they together revolve and slip down. Our method simulates such motion with the particle model. In addition, snow on the windshield is gathered by a wiper. To represent this, a mesh is attached along the windshield wiper. The mesh and the wiper rotate together. When a snowflake contact to the wiper blade, it is stored to the cell of the mesh located at the contact point. If the cell is already filled, the snowflake is stored to the more outside cell. As the result, form of the snow stacked on the wiper is created. It is confirmed that our method can display similar movement of snow on the windshield in the comparison of video.
