【Abstract】 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.更多还原
