We present a hybrid model for 3D cartoon water modeling and rendering. First

we constructs some cartoon water forms and arranges them on 2D working region and map them onto 3D surfaces. The region covered with an obstacle object is detected on the 3D surface and then mapped reversely onto the 2D working region. The spray form is added if the flowing water forms collide with the mapped region. Our method is able to preserve the cartoon style of water forms during the interactions between the obstacle object and the cartoon water. Moreover

user can adjust the water forms

positions and the movement rate with ease. The real-time rendering is achieved by taking advantage of the graphics processing unit.
