【摘要】：目前,Marching Cubes算法是一种热门的三维建模方法,然而,对于由中国水墨画的笔画线条所构成的复杂形状,其应用具有一定的局限性.针对生成三维水墨动画这一挑战性课题,提出一种由中国水墨画图像构建对应三维模型的交互式方法.同时,基于该方法,设计实现一个半自动的三维模型构建工具:首先,交互式提取输入的水墨画图像中的笔画;然后通过生成笔画的二维表面网格和三维蒙皮网格输出相应的三维模型;最后,将原有水墨画中的墨色纹理用来渲染生成的三维模型.实验结果表明,该方法适合将二维水墨画图像对象转化为三维模型.此外,生成的三维模型数据符合主流建模及动画软件的格式要求.因此,在三维场景中,该项研究工作除了表现水墨画的墨色效果,也展示出其笔画的造型艺术特征,还可应用于三维水墨动画的制作,提高制作效率.
[Abstract]:At present, Marching cubes algorithm is a popular 3D modeling method. However, it has some limitations in the application of complex shapes made up of Chinese ink and ink strokes. Aiming at the challenge of generating 3D ink animation, an interactive method is proposed to construct the corresponding 3D model from Chinese ink and wash images. At the same time, based on this method, a semi-automatic 3D modeling tool is designed and implemented: firstly, the stroke in the input ink and wash image is extracted interactively; Then the corresponding 3D model is output by generating the 2D surface mesh and the 3D skinned mesh. Finally, the ink texture in the original ink painting is used to render the generated 3D model. The experimental results show that this method is suitable for converting 2D ink painting image object into three dimensional model. In addition, the generated 3D model data meet the format requirements of mainstream modeling and animation software. Therefore, in the three-dimensional scene, this research work not only shows the ink effect of ink painting, but also shows the plastic art features of its strokes, but also can be used in the production of three-dimensional ink animation to improve the production efficiency.
