In the geometry compression approaches presented in this thesis, the representation of a polygonal mesh is divided into two parts: the first part is termed topology information, which refers to the connectivity of the vertices in the mesh; the second part is termed as geometry information, which refers to the vertex locations and other attributes including color, normal, texture coordinates etc.

在本文中，一个多边形网格的数据表示为两部分：第一部分叫做拓扑信息，指多边形网格顶点之间的连接关系；第二部分叫做几何信息，指多边形网格坐标、颜色、法向以及纹理坐标等几何属性。

This paper presents a new rendering algorithm by the contrast between the Flat method, Gouraud method and Phong method, through which the color of each pixel can be figured out under the lighting model after the coordinates and normal of every corresponding point on the 3D-object surface have been calculated from the pixels in the range where the 3D-object is projected onto the photo, in order to provide each pixel a real color and get an image with strongest feeling of reality.

本文在对比研究了真实感图形生成中传统的Flat，Gouraud，Phong等明暗渲染方法后，提出了一种新的明暗渲染方法。在图像平面三维物体的投影范围内，由图像的像素坐标求出物体模型对应点的三维坐标及其法矢，然后对每个像素点根据光照模型来计算其明暗度。这种方法能够最大可能的保证图像中每一像素点明暗度的真实性，从而使所生成的真实感图像更加逼真。

Direct difference is sensitive to noisy data, so a threshold limitation is given, which can not only filter the result from noisy data but also pick edge points up according men's desire. On the other hand, artificial intelligence is used for segmentation in reverse engineering. Because the essence of segmentation is clustering similar characteristics and self-organizing feature mapping is one function of neural network, SOFM network is used for segmentation in the thesis, coordinates and normal of data points is took as the characteristics vector.

第二种方法，基于双向角度微分的边点提取法，针对三维正交模型采用基于截面线的方式组织数据，此方法比基于曲率半径方法更简洁，不用进行曲面拟合，大大提高了计算速度；计算过程中由数据点的直接差分逼近微分，但直接差分对数据误差敏感，为此，本文提出了阈值过滤的方法，一方面过滤了数据误差在计算结果中引起的噪音，另一方面可以按照设计意图控制边点的提取；来决定是否提取光滑交接的边点。

Since two curves have the same coordinates and unit normal vector at the contacting point, the problem of the mesh of two planar curves is transformed into an ordinary differential equation by vector analysis. We have the solution to the equation by numerical method and computer calculation. After repeating the way of computing the solution to the equation, we have the contacting points.

因两曲线於接触点的位置相同，单位法线向量相等，由向量分析使曲线接触问题转变为常微分方程式，藉助数值计算与电脑运算得到方程式解，重覆计算方程式的解即可得每一接触点的位置。

The essence monopolizes the way execution most first floor duty, guarantees the system normal movement - coordinates the many concurrent advancements, manages the advancement use the memory, causes them mutually between not to have the conflict, satisfies the advancement visits floppy disk request and so on.

内核以独占的方式执行最底层任务，保证系统正常运行——协调多个并发进程，管理进程使用的内存，使它们相互之间不产生冲突，满足进程访问磁盘的请求等等。

Linear shift code, known polygon vertex coordinates, can be the edge of the polygon shift its normal direction and then get a new polygon from the vertex.

详细说明：直线偏移代码，已知多边形顶点坐标，可以将多边形各边沿其法线方向平移距离然后得到新的多边形顶点。

Use the vertex normal, transformed to camera space, as input texture coordinates.
