Cartoon Hair: Blobby Model Based Approach
نویسنده
چکیده
This papor dcsc.ribcs a new hair repre.sentation techiiiqiui for drawing 3D CG characters. In our approach liair models are representcid by skeleton-based implicit surfaces. Implicit inodoliiig allow.s ropresiuitlng union and division of wisp.s of hair by n.sing a blobby model. Our method gets hair skele tons as input data. The skeleton is interpolated using a spline function and then implicit surface of hair shape is gen erated by the skeleton. And ray marching method is used to compute intcrs<K'tion of ray and surface of hair implicite function. Finally, non-photorealistic rendering is applied to generate re.sulting image as output. In our approctch hair skeletons are created by operating GUI skeleton editor or tracking hand motion using depth camera. This .system al lows the artist to create skeleton with the help of intuitive operations. Physically-based animation of the hair model is also proposed. In our approach, spring-mass model is lused to animati! a solid hair shape.

Modelling and Animating Cartoon Hair
In this paper we present a technique for the modelling and animation of cartoon hair based on its tendency to be drawn and animated in clumps. In our approach the primary shape and motion of the hair is defined by an animated NURBS surface, thus allowing animators greater artistic control. The basis of the hair clumps is formed by key hair curves that are generated along the isocurves of the or...
متن کاملNon-Photorealistic Rendering of Hair for Animated Cartoons
In cartoon drawings, hair is a strong vehicle of personality, emotions and style. In this paper, we present a powerful procedure to imitate the appearance of cartoon-like hair with a small set of parameters. Our approach is inspired by an inking technique called feathering, which consists of drawing hatches along the hair orientation while emphasizing the highlights with ink stains. Our system ...
متن کاملA Physically Based Deformation Model for Interactive Cartoon Animation
We present an approach for automatic cartoon-style motion dramatization suitable for interactive realtime animation. The system is built upon a physically based deformation model previously discussed in [GMPR06] and achieves squash-and-stretch cartoon deformation relevant to the current object velocity by controlling the deformations in the physically based model. As an improvement over previou...
متن کاملCaricature System using Moving Least Squares based on Justin
In this paper, we propose a new automatically generation system of caricature which emphasizes the unique characteristics of the input images. This system can create the cartoon character similar to user’s features by using set rules adopted a particular artist's technique. Input image is transformed by using MLS(Moving Least Squares) approximation[1] based on a predefined cartoon character’s i...
