我们在场为 3D 的新奇盔甲结构明白表示形状，叫了为骨胳的球短的 SBall，它包括二部分：一架一个维的骨骼和事件成球形。我们的算法主要集中于构造盔甲结构。这结构基于是等价于形状的 homotopy 的一架近似骨骼。在结构的每个球连接一个骨胳的关节和形状的一个内部区域。形状表面上的边界顶点用球集合的力量图被依附到 SBall 上。一个双边的过滤算法和一个变化分割算法被建议提高 SBall 的质量。最后，这结构的应用被讨论。

英文摘要：

We present a novel armature structure for 3D articulated shapes, called SBall short for skeletal balls, which includes two parts： a one-dimensional skeleton and incident balls. Our algorithm mainly focuses on constructing the armature structure. This structure is based on an approximation skeleton which is homotopy equivalent to the shape. Each ball in the structure connects a skeletal joint and an interior region of the shape. The boundary vertices on the shape surface are attached onto the SBall using the power diagram of the ball set. A bilateral O~tering algorithm and a variational segmentation algorithm are proposed to enhance the quality of SBall. Finally, applications of this structure are discussed.
