【摘要】 复杂网格的编辑是三维动画设计的关键技术,已经出现了多种比较成功的方案和算法。在研究了三维网格的骨架生成及其优化方法的基础上,提出了一种基于骨架的局部网格编辑算法。先由用户确定编辑区域,绘出与变形后的骨架相对应的编辑曲线,再根据网格顶点与骨架曲线及编辑曲线之间的对应关系,实现网格结点的平移和旋转等编辑操作。实验证明,该算法的实现具有编辑直观、易于控制等特点,能够很好地应用于网格的局部特征编辑。更多还原

【Abstract】 The editing of 3D meshes is the key of computer animation technology,and there have been several successful schemes and arithmetics.After the studing and analysis of the methods of 3D mesh’s skeletogeny and skeleton’s optimize,a skeleton-based arithmetic of local edit for 3D meshes has been proposed.At first,the editing area and the editing curve are got from users.Then,the vertices in this area are changed and rotated smoothly corresponding the changes from skeleton to editing curves.Results of experiment show that the implementation of this arithmetic is intuitional and manipulable.The local edit of irregular meshes is completed easily and efficiently.更多还原
