ABSTRACT
An efficient method for simulating cartoon style rain in 3D environment is proposed here. By taking advantage of the parallelism and programmability of GPUs (Graphic Processing Units), real-time interaction can be achieved. Splashing of raindrop is simulated using collision detection, series of stylized textures and rotations of point sprites. To simulate wind-driven raining effect, the motion of particles can be freely controlled based on Newtonian dynamics. We can also control the size of raindrops dynamically by using different textures or changing the size of point sprites. Many experiments have been done in 3D scenes with different complexity and GPU-based stylized rendering. The experimental results demonstrated the efficiency of our method for real-time rain simulation in cartoon style with complex geometries of 3D scenes.
