卡通流水生成系统

介绍了一个卡通流水生成系统。在系统中用户先交互画出少量的控制点，再通过选择水波类型以及输入少量参数，系统便可以自动生成与目前电视动画中的卡通流水质量相当动画序列。系统主要包括4个部分：流水路径控制模块，水波类型控制模块，水波以及浪花生成模块。流水路径控制模块根据用户输入的控制点和透视参数生成流水路径控制曲线族以确定流水的路径和水面覆盖范围，水波类型控制模块则定义了卡通流水中常见的水波类型，水波以及浪花生成模块则根据系统内部定义的水波类型生成不同的水波与浪花。该系统可以使普通的用户把复杂的卡通流水手工绘制劳动转化成输入少量的点和参数，从而显著提高卡通动画的生产效率并节约大量纸张。

A Cartoon Water System

We present a system capable of generating cartoon water with the quality compatible to the cartoon animation we can see from TV. The system consists of four parts: water path, water type, water wave and foam. The water path is defined by a few control points specified by the user according to the scene, the water type defines some common water forms we can see in cartoon animation and, according to the water type selected by the user, the system generates cartoon water with appropriate forms automatically. Our system converts laborious cartoon water drawing into specifying a few control points and parameters, so ordinary users without special training for drawing cartoon water can use the system to achieve the same goal.
