In addition combining opengl technology , we can translate the source shape data of targets displayed on the computer screen to the data for rcs computing . " graphical electromagnetic computing ( greco ) " was presented in these conditions , which has many merits such as detecting shadowed regions automatically , computing in real time and accurately and so on 图形电磁计算( graphicalelectromagneticcomputing ， greco )方法就是在这样的环境下产生的，它具有诸如自动实现消隐，计算速度快，精度高等优点，目前被认为是求解高频区复杂目标的最有效的方法之一。
The process - established module is characterized that what you see on the computer screen will be what you want when you work out the process , that the process can turn to the next line automatically , that the style of dimension tolerance , the shape and position tolerance accords with the state standard and that simple figures can be drawn by means of ole 系统的工艺编辑模块使得用户以所见即所得的方式完成工艺过程卡和工序图卡的编辑，能够实现工艺内容的自动换行和公差的上下标注，能够实现粗糙度和形位公差的国标标注，能够利用ole技术实现工序图的绘制。
In addition , this article analyzes the structure of trunk orthosis cad system , and discusses the functions and how to realize those functions of each part according to the aspect of human body , surface modeling is used to build the three - domain trunk model ; and then through opengl technique , the model is displayed on the computer screen ; then by involving the technology of man - machine interacting , the model can be edited according to the respective body characteristics of different patients - as the improvement of man - machine interactive technology , model can be edited more freely 文中重点分析了躯干矫形器计算机辅助设计系统的组成，并对各个组成部分的功能和实现方法进行了讨论。针对人体躯干的外形特征，使用表面建模方式对躯干建立三维模型，并利用opengl技术完成模型的显示；再利用计算机实现人机交互功能，针对每位患者的形体特征对模型进行局部修改；随着人机交互技术的提高，模型修改将更加具有任意性的特点。
On the study of interpolation algorithm and cagd theory , two interpolation algorithms are analyzed , basic spline and nurbs interpolation , and thrice basic spline interpolation algorithm is proposed to realize path planning . the simulation of industrial robot is also important in the research of robotics , which displays the robot model on the computer screen and facilitates the devise of robot 在机器人运动空间的插值算法和计算机辅助几何设计理论的基础上，分析了两种直接插值算法： b样条和nurbs曲线插值算法，提出一种三次b样条插值算法来实现工业机器人运动路径规划，提高了插值的精度和计算速度。
Simultaneously with the micro - displacement started the processe of the grating sensor measuring the displacement and image collection of the system . the grating sensor ( length gauge ) measures the displacement of the dial gauge with surveying rod . it is delivered to the computer with a block k220 in real time and the dial image by ccd camcorder is shown on the computer screen with the image collection card in real time 在实现微量进给的同时，启动系统的光栅位移测量过程和图像采集过程，光栅传感器(长度计)测得指示表测杆的位移量，由计数卡ik220实时传送给计算机，由ccd摄像头摄取的表盘图像经图像采集卡在计算机屏幕上得以实时显示，最后通过对指示表指针位移计算处理与光栅传感器测量的位移量进行比较，得到指示表受检点的示值误差。
