Abstract: Many models for dealing with water effects have been proposed in the past two decades, most of which, however, were aimed at generating realistic water images and little effort has been spent on modeling cartoon water effects A model capable of generating cartoon water jet in a procedural manner is presented in this paper It is shown how the skeleton for water jet is abstracted from hand drawn series and, based on this skeleton, wave textures and drops with hierarchical models are reproduced By stochastically varying the parameters, the model is able to generate the water jet effects automatically in 3D while keeping the look of traditional cartoon
