Abstract:

To solve the problems such as unreal effects,incomplete details in the rain scene,an algorithm to simulate water surface after rain hitting by combining Meatball with mass-spring water surface was presented.First,the raindrops model was estabished with particle system combining textures,and the water surface model was established with the mass-spring model.Secondly,the algorithm animated half globular bubbles after rain hitting with Meatball.Thirdly,water splash was simulated by means of the particle system and a gradual thinning and syncretizing technique.Finally,with the help of Cg language,the reflection and the refraction effect on the water surface,globular bubbles and water splash were simulated.The experiment shows that this approach can be used to simulate rain scenes efficiently and realistically.

Key words: rain scenes, mass-spring, model Metaball, particle system, dynamic texture
