摘要： 网格模型变形往往需要保持局部几何细节，Laplacian网格变形算法能够较好地保持局部几何细节特征，但细节特征描述子-Laplacian坐标的计算欠缺精确性。从平面多边形中值坐标的角度出发，对Laplacian坐标进行重新定义，将顶点的一阶邻域投影到顶点处切平面上，根据顶点相对投影点的中值坐标构建的Laplacian坐标能够精确地描述模型的局部几何细节特征，实验验证能够获得较好的编辑效果。
关键词: 网格变形，Laplacian网格编辑，中值坐标，几何细节保持
Abstract: A rectuirement for Mesh deformation is to preserve local geometric detail. Laplacian mesh editing can meet this rectuirement, but Laplacian coordinates is not a accurate form to describe the local detail. This paper defined the Laplacian coordinates through mean value coordinates. First projects 1-ring of a vertex onto tangent plane, then constructs Laplacian coordinates use the mean value coordinates of the vertex. The result shows that this definition is accurate to describe local detail.
Key words: Mesh deformation, Laplacian mesh editing, Mean value coordinates, Geometric detail preserving
