在二维空间模拟卡通流水和草地

Simulating Cartoon Water Forms and Grass in 2D Space

不同于真实感图形的处理,本文给出一种NPR(Non-Photorealistic Rendering)方法,使用计算机图形技术来模拟卡通形式的流水及草地,算法基于一些简单的数学公式,有很快的执行速度.算法中将卡通流水分为静态要素和动态要素,以正弦波来模拟水波的形状,通过其运动控制来达到流水的卡通动画效果.另外使用笔刷单元并在上面随机分布散乱点的办法来模拟草地.

In this paper, we give a Non - Photorealistic Rendering based method apart from photorealistic effects to simulate cartoon water forms and grasses in 2 - dimension space. In this method only simple mathematic formula are used. First we analyze the hand drawn cartoon flowing water series and extract the static and dynamic elements associ- ate with them. Second, we make use of sinusoidal function to model glowing water waveforms and animate them by motion controlling. In grass model we use brushes and random dots distributed over a given region.
