| 中文摘要: |
| 提出一种基于组件匹配、融合的三维形状生成算法。根据Hausdorff距离对输入形状的各组件进行匹配,形成匹配组件对,进行球面参数化映射,合并组件对的球面网格模型；通过反映射建立组件间的顶点对应关系,进行插值融合,采用不同的融合系数,生成一系列连续变化的组件；然后根据输入形状的连接关系进行重新连接,生成完整的变形形状。实验表明本算法可以生成合理、相似的变形形状,同时保留了输入形状的功能和表面细节。 |

| A 3D shape creation algorithm based on component matching and merging is proposed. Components are matched between two input shapes according to the Hausdorff distance metric to generate matched components. The components are mapped onto the spherical surface to carry out the spherical parameterization. The spherical mesh of matched two components are merged, and the vertices correspondence between matched component-pairs are built through adding vertices and reverse mapping. The interpolation is concluded to create a series of in-betweens in terms of the merging coefficient. Then, the novel variations are obtained by relinking components reference to the connection of input shapes. Experiments show that the algorithm can generate reasonable and plausible variations, while retaining the function and adequate surface details of the input shapes. |
