Remember that the z-coordinate is negative because OpenGVS uses the same right handed coordinate system to remain compatible with OpenGL (remember,+Z is out of the screen toward the eyepoint, so we are conceptually moving our sample object "into the screen" away from the eyepoint so we can see it).

记住Z坐标是相反的，因为OpenGVS用一样的右手坐标系统去保留对OpenGL的兼容（记住，+Z从银幕而出指向眼睛的，所以我们观念性的移动我们的例子，使之背离眼睛进入荧幕，所以我们能看见它）。

ABSTRACT: By using image processing software, based on the coordinates of clear points in images and the theoretical coordinates of the points in the reference coordinate system, the coordinate relation multinomial of pre-and post-correction control points can be established by means of the digital image correction technique and the coefficient in the multinomial can be sought on the basis of the coordinates of a certain number of control points.

前言 考古绘图一直是考古学研究中不可或缺的重要技术，能够反映考古遗迹的分布状况或者典型器物的多重特征。但是随着考古学研究的深入和对相关技术手段需求的增加，考古绘图技术却始终停留在通过直尺等量取数据、再使用直尺和铅笔绘图的水平上，成图精度很低，周期较长，图形品种单一，远远不能满足现代考古学研究的需要。

In this paper, draw the idea of beam unit, the bias along the vertical box is divided into a number of oblique beam. On the basis of analysis of the displacement, through positive and oblique coordinate transformation relations, and directly built on the oblique coordinate system to describe the methods of displacement unit space. With potential energy principle is derived in oblique beam element stiffness matrix and the establishment of the finite element formulation. The preparation process of the finite element analysis is used to verify the structure of bias.

On one hand, the integration between literary autonomy and social heteronomy is the abscissa of the coordinate axis. On the other hand, the integration of ancient and present poetic resources, and Chinese and western poetic resources is the ordinate of the coordinate axis. Integration in Wu Mi\'s poetic thoughts is embodied in two aspects: Firstly, it means the integration of ancient and present poetic resources, and Chinese and western poetic resources. Wu Mi maintains that various poetic resources should be treated equally so as to find the similarities and differences among them. Only with a broad cultural view and calm attitude toward various poetics resources can a new system of modern poetics be achieved.
