Abstract: Animating splash effects is a time-consuming task in cartoon.We present a model for automatic generation of 3D cartoon splash.First,we construct a parabolic curve and use it to form a surface as the underlying model of the splash,then we model dynamic textures for the splash with the spline based on the features of hand-drawn water splash.As for spray forms surrounding the splash surface,we model them with a few control points and interpolate them with the spline according to their shapes.Spray forms of varying shapes are finally rendered on the billboard distributed around the water splash.Our method extends the splash animation to 3D space while retaining the style of hand-drawn cartoon.Moreover,our model allows high-level parametric control over the splash effect animations that change from gentle to violent.
