卡通角色艺术风格化变形方法

Artistic Style Deformation for Cartoon Character

  • 摘要: 在总结卡通形象的艺术创作方法及其特点的基础上,将图形变形技术与艺术风格化技术相结合,提出一种卡通造型风格化变形规则套用的方法.首先对用户输入的卡通形象进行变形区域的选取,生成用于控制所选区域变形的二维自由变形(FFD)控制点网格;然后通过控制卡通图形上控制点的位置或直接套用已有的艺术化变形效果模板,采用图形区域分级策略及FFD方法对所选区域进行变形,使该区域变形为新的具有与模板相似艺术风格的效果,从而最终生成新的卡通造型.实验结果表明,与采用人工方法对卡通造型进行手动调整或重绘相比,该方法更加简易和高效,变形后的艺术化效果也更加丰富,其适用于卡通动漫领域的非真实感人物造型的风格化绘制.

     

    Abstract: Artistic styles reusing is a commonly used method for the fast creation of cartoons. Computer graphics deformation techniques further promote the creation of cartoon more automatic and intelligent. Based on the study of the artistic creation of cartoons, this paper presents a method for reusing artistic deformation styles by combining shape deformation with the artistic style reusing techniques. First of all, the solution selects the deformation area of the cartoon character from a user and generates the free-form deformation control points to control the deformation of the selected area. Then, the deformation is implemented by changing the positions of the control points or applying the stylized deformation template. Grading strategy and free-form deformation also contribute to the deformation. Finally, a new character is generated with its style similar to the template. Experimental results show that the proposed method has obvious operability and automaticity compared with the traditional methods such as manual adjusting weights and repainting. The method can be applied to fast drawing of cartoon, animation, and other non-photorealistic rendering applications.
