New York magazine won the overall title last year with its cover featuring a smiling Spitzer and the word "brain" in a red box with an arrow pointing to what ASME called "the area of Spitzer's anatomy that seemed to have been thinking for him."

纽约杂志》获选去年最佳封面奖，在获奖封面上，斯皮策灿烂地微笑着，有一个写着"brain"字样的红方格，方格旁边的一个箭头指向斯皮策的下身，ASME称之为"替斯皮策思考的部位"。

Lawyers of the past, haughty, pleading, beheld pass from the consolidated taxing office to Nisi Prius court Richie Goulding carrying the costbag of Goulding, Collis and Ward and heard rustling from the admiralty division of king's bench to the court of appeal an elderly female with false teeth smiling incredulously and a black silk skirt of great amplitude.

The ebb had already run some time, and I had to wade through a long belt of swampy sand, where I sank several times above the ankle, before I came to the edge of the retreating water, and wading a little way in, with some strength and dexterity, set my coracle, keel downwards, on the surface.

落潮已有一段时间了，我必须跋涉一段很长的沙滩（有好几次我的脚陷进了泥沙中），才走到了正在退下去的水边。在水中趟了几步后，我稍稍用力就麻利地把小船平放在水面上。

This thesis contributes to geometry compression in the following aspects: Proposes a method of progressive spherical mesh parameterization based on local parameterization by directly projecting the deleted vertices to its neighborhood. Based on spherical mesh paramterization, an adaptive subdivision remeshing method by progressivly redistributing of sampling points is proposed, by this means, the main geometry information of the original mesh can be captured with only a small amount of samples, it can also be used in mesh simplification. By regarding attributes binded on mesh vertices as geometry signals and transferring them onto a uint sphere by means of spherical mesh parameterization, meshes with different attributes are compressed with spherical wavelet successfully with high compression rate. As a kind of lossy geometry compression technique, two mesh simplification algorthimes are also presented in this thesis.

归纳起来，本文的主要贡献有：提出了以直接投影局部参数化方法为基础的网格累进球面参数化方法；在网格球面参数化方法的基础之上，提出了一种基于累进优化布点方案的网格细分采样方法，该方法可以用很少的采样点就可以捕获到网格的主要特征，因此我们也将其用于后面的网格简化工作当中；通过将网格顶点上定义的各种属性看成几何信号，并以网格球面参数化为手段将几何信号迁移到单位球面上，从而成功地实现了用球面小波对各种几何信号的压缩；作为一种有损压缩方法，本文还提出了基于统一距离的网格简化算法和基于重采样的网格简化算法。
