计算机生成卡通烟雾动画

给出了一个用于二维计算机动画烟雾的模型，这里着重强调的用计算机生成卡通风格的烟雾效果。首先介绍如休从手工绘制的卡通烟画面中提取烟雾骨架的静态结构与动态，然后沿骨架进行不同的形状绘制来生成卡通烟缕和烟团，引进随机分量控制，该模型可以自动生成无重复机械感的并与卡通风格一致的烟雾序列画面。

Computer Generation of Cartoon Smoke

This paper presents a model of smoke for 2D computer animation. Here the emphasis is on the stylistic representation of the smoke. It shows how to abstract static and dynamic structures of the smoke skeleton from hand drawn series and, based on those structures, reproduce smoke skein and smoke puffs with proper rendering models. By stochastically varying the parameters, the model is able to generate smoke effects automatically with the look of traditional cartoon and avoid using the repeated cycles that may cause mechanical looking of the effects in hand drawn animation.
