用随机正弦波拟合卡通流水

CARTOON WATER FORMS SYNTHESIS USING RANDOM SINUSOIDAL FUNCTIONS

在过去 2 0年中人们提出许多处理水运动的方法 ,但大都致力于生成真实感的动画 ,而对传统手工绘制的水运动效果建模问题几乎无人涉及 .给出一个等级结构的卡通流水模型 .首先分析卡通流水的绘制过程 ,从中提取卡通流水的静态要素与动态要素 ,然后以正弦波为基础对其幅度、频率以及相位进行随机扰动定义水波形状 ,并在指定边线范围内控制它们的运动来生成卡通流水 .此外还给出了生成三维卡通流水的方法以及相应的动画图例 .

Many methods dealing with water movements have been proposed in the past two decades, most of them however focus on generating realistic animation and relatively little effort has been spent on simulating hand drawn water series. In this paper, a model capable of generating cartoon water automatically is presented. First, the hand drawn cartoon flowing water series are analysed and the static and dynamic elements associated with them are extracted. Second, use is made of sinusoidal function by perturbing its amplitude, frequency and phase randomly to model flowing water waveforms and animate them along the path specified. Finally, how to generate cartoon water in a 3D scene is described and relevant examples are shown.
