关键词：3D MAX；建模；自控元件 ABSTRACT The application of computer moving pictures in education field has begun from recent years. The main use is to assistant teaching and training which can improve the students' perceptual knowledge, making tedious teaching imply in the vivid and amusing moving pictures. The application in self-education and teaching is particularly important, for some current course are too intricate and abstract ,and can't demonstrate to students, all that is a problem to either students or educators. The network-teaching ,computer moving pictures used for assistant teaching and training resolve this problem just in time. It uses three demons to set up the models, brings the training and demonstration which can't be taken to the class, and makes it realize through the computer. In class, teachers can teach lively, making the puzzle course become simple. After class students can listen to where he hasn't comprehended very well again and again, and doing that is good for revision, firm master, and can improve learning efficiency.This paper has elaborated in detail the application of the three demons in modern life , the development prosper and main means to carry out. The author eventually choose 3D max as the carrying out means, emphasized the advantages and disadvantages of 3D max, and how to use 3D max to make three demon models of automatic component.Key words: 3D max; model ; automatic component 目 录 第1章 绪论 1 第2章 三维动画的应用 42.1 方案论证 42.2 3D MAX软件介绍 62.3 小结 9 第3章 元件建模 103.1. 制作直流伺服电机的模型 103.1.1 支流力矩电动机 113.2. 制作交流伺服电动机的模型 223.3. 三相步进电动机模型的制作 293.4. 制作力矩式自整角机的模型 353.5. 制作旋转变压器的模型 363.6 小结 37 第4章 模型的后期处理 384.1 标准渲染 384.2 灯光 424.3 摄影机 444.4 小结 44 结论 45 参考文献 46 致谢 47 第一章 绪论 计算机在教学领域的应用是这几年开始的，计算机动画用于辅助教学和辅助训练，可提高学生的感性认识，使枯燥乏味的教学寓于生动、有趣的动画之中。三维计算机软件的制造的模型的表现能力越来越好，他可以帮助将复杂的课程，难以理解的问题变得简单，形象，易于理解，消化。
尤其是在自学与教学领域的应用，由于现在的一些课程，如自动元件，电机拖动原理，自动控制原理等课程十分的难懂抽象，无法向同学演示，这对于无论是学习者还是教育者都是个问题。网络教学，计算机动画用于辅助教学和辅助训练适时解决了这个问题，应用三维建模，将无法带到课堂的训练，演示用计算机实现。
在课上老师可以形象教学，将难以理解的课程变的简单，课下同学可以将自己理解不好的地方反复听，反复理解便于复习，牢固掌握，提高学习效率。计算机动画用于辅助教学真正的适合了课程发展改革的要求，让教的行为与学的行为可以发生在不同的空间，时间。
为学生与老师都提供了便利。学校的实践层面引入网络，真正的多媒体制作涉及教学方案设计，文学脚本撰写，平面设计（美工）创意，2D 、3D的动画制作，视盲频素材采集和编辑编程方面等等，对人力资源的技术文化水平很高要求，对制作平台要求硬件很高。
我们可以充分利用已有的公网资源，充分运用已有的权威机构专业网方面、个人特色网络、老师的饿精力更多地集中在探究学习活动方案的设计上，更多地集中在学习者学习活动的辅导上。本次毕业设计主要完成的是自动元件的网络教学系统，它包括教学部分，练习部分，考试部分，问答部分，留言部分等。
为了更为形象的再现自动元器件的结构，工作情况，采用了三维软件建模。三维计算机动画是采用计算机模拟现实中的三维空间物体。
在计算机中构造三维的几何造型，并赋予表面材料、颜色、纹理等特性，然后，设计造型的运动、变形，灯光的种类、位置、强度及摄像机的位置，焦距，移动路径等，最终生成一系列可动态播放的运动图象，并可以将制作的动画输。

Since our reform and opening to the world, china has been make great strides forward and change greatly in all fields such as economy, culture and politics .when its comes to culture,the strides are showed on the rise of female's educational level and The ratio of female in universities and colleges.even the ratio reach up to 50%.we know that the graduated students is one of the main part of job hunters.The inequalities between the sexes were mirrored in social life ,especially in obtaining employment .
The inequalities between is obvious, most of company would like to choose male instead of female when meeting the same condition interviewee, and female often given lower salary compare with male when doing the same work in the same company according to sex determination. It is worthwhile to note that female are more likely restricted and aggression in gender inequality in obtaining employment.gender inequality effect female's development and future, neglect social integration, harm social cooperation of genders, which lead to consequence seriously such as the lack of coordination between male and female, sound development and the normal operation . the root cause of these problems include sexual discrimination, employing units exist prejudice and angular impression involved in different vocations and some personal reasons from students as professional choice and mental qualities.in order to resolve these problems, we need the public change those angular impressions, employing units
broad vision with development. Meanwhile, as students, who need build health personality and learn more useful knowledge.
The paper will analyze and discuss
the phenomenon of gender inequality of universities and college students in china ,and
conclude some effective Issues and Countermeasures

虚拟软件Creator与3D MAX结合制作虚拟三维场景摘要：介绍了可视化仿真建模的特点，提出了一种利用3D MAX软件作为辅助建模的方法：在3D MAX下开发的3D模型，以3ds的格式存储下来，然后导入Creator中，在Creator下修正后以flt格式保存，使以Creator构造复杂模型所遇到的难点得到解决。
关键词：可视化仿真；建模方法；Creator;3D MAX1可视化仿真概述一般来说，要通过仿真来认识某个系统，首先需要建立一个可以尽可能逼真模拟该系统的模型，然后通过分析反复运行该模型获取的各种数据和结果来认识该系统。考虑到真实世界的复杂性，尽管“仿真”不是认识世界的唯一途径，但是对于那些具有很多不确定因素和随机性的系统来说，应用计算机仿真技术可以更好地达到认知的目的。
从概念上来说，可视化就是一种用图形或图像来表征数据的计算方法，即利用计算机图形图像技术，将一维数据转化为可观察的二维或三维几何表示，从而达到增强人们对抽象信息认知的目的。2可视化仿真建模的特点可视化仿真衬里性和交互性的本质特征和衬里渲染的底层实现过程，决定了用于可视化仿真系统的三维模型数据库需要具有不同于传统三维模型数据库的一些特点，例如：模型的多边形数量要尽可能少；模型数据的构造要尽可能简单；模型数据库的结构要便于进行遍历操作；模型数据库要能够被应用程序快速读取；模型数据库可以包含各种约束限制信息。
3 Creator与3D MAX的结合3.1基本建模环境模块Creator建模系统的基本模块，其基本功能是为用户提供一个功能强大、交互式的可视化建模环境，用户可以快速地创建三维仿真模型。它的主要功能包括：强大的多边形建模功能；强大的矢量化建模功能；强大的模型数据库控制功能；强大的纹理映射和贴图功能；支持多种格式的三维模型格式转换；支持大面积地形的精确生成；支持多细节层次（LOD）建模；支持多自由度（DOF）建模；支持光点系统模拟；支持序列动画模拟。
3.2地形建模模块（1）使用3D MAX来进行地形的创建。在场景中创建地面：单击Create>Geometry>Plane按钮创建一个平面，将它的LengthSegs和Width Segs都设为25。
(2)选中平面，右击鼠标，在右键菜单中选择Convert toEditable Poly命令，将平面塌陷成为可编辑多边形物体。（3）单击Editable Poly前面的+，在下拉列表中选择Vertex次物体，然后在Soft Selection（软选择）卷展栏中勾选下面的UseSoft Selection（使用软选择）项，调整它的Fallof(f衰减)值。
这样一来，在物体上选择、操作一个点时，就能影响它周围衰减范围内的点了，适当向上移动刚才选中的点并查看效果。（4）任意调整Pinch（收缩）、Bubble（膨胀）的数值，改变衰减范围内对周围点的影响强度。
在Soft Selection卷展栏中，还有一个可以自由绘制选择范围的方法，单击Soft Selection下方的Pain(t绘制)按钮，可以在视图中的物体上任意绘制自己想要选择的区域。（5）使用鼠标任意绘制选择区域，来制作崎岖不平的土地。
（6）使用“选择并移动”工具向上沿Z轴拖动鼠标，制作出地形的起伏（见图1）。(7)取消Lock Soft Selection（锁定软选择）的勾选，回到选择点的状态，关闭Pain(t绘制)状态（见图2）。
(8)在Paint Deformation（绘制变形）卷展栏中单击Relax（松弛）按钮，可以在物体上通过鼠标绘制的方法，将一些过于尖锐的起伏变得比较平滑。（9）单击Push/Pul(l推/拉)按钮，可以在物体表面绘制起伏并塑造形体。
（10）再次单击Relax按钮，在物体表面抚平一些过于尖锐的起伏，让它们变得比较平滑。（11）如果操作满意的话，可以单击Rever(t复原)按钮，在物体表面进行覆盖操作，使刚才的凸起恢复平坦。
（12）待效果满意后，单击Commi(t提交)按钮确定操作，如果对结果不满意，还可以单击Cance(l取消)按钮取消刚才的操作。在这里，单击Commit按钮确定，这样就完成了崎岖地面的操作。
3.3 3ds文件导入creator在3D MAX的建模完成后，模型以3ds的文件存储。一个3ds的文件包含一系列的有用信息，它们用于描述由一个或多个物体构成的3d场景的每一个最小的细节。
3ds文件的二进制信息是用特殊的方式写入的。3ds文件导入creator有两种方法：第一种方法是直接导入，这种转换过程会有一些错误产生，例如遗失或置换面数。
这些错误可以用creator的转换，复制工具校正。另一种方法是模型附上3D MAX的网格形式，再导入creator。
在Creator中，x为水平轴，y轴正交于x轴，z轴垂直于由x和y构成的平面。Creator是一个三维的坐标系统，计算机显示的平面是二维的，放置数据库元件于三维的轨迹平面会更精确。
轨迹平面有两部分：一是平面，三维的数据库空间。一般而言，坐标系里，鼠标左键是放置元件于轨迹平面中。
二是位于轨迹平面的二维网格，网格被认为是笛卡儿坐标系网格或极坐标系网格（见图3、图4），可以是可见的，或是不可见的。 OpenFlight是creator文件的格式，具有层次化结构。
这种结构定义了数据库中节点之间的关系，即节点是以树状形式连接在一起的，从最上层的根节点向下到体节点、面节点和底层的点节点，点节点并不出现在层级视图中。然而，在3D MAX中没有。

Nowadays, our domestic private enterprises have developed, and successively emerge a number of large and medium-sized private enterprise with abundant strength, and private enterprises in absorbing employment personnel, increase the fiscal revenue plays an increasingly important role. At present, however, the overall competitiveness of domestic enterprises is weak, plus a foreign-capital enterprise after China's entry into wto, China's entering domestic enterprises, especially private enterprises are faced with severe tests. How to improve the private enterprise of domestic enterprises, especially the synthesis competitive ability, the dilemma that has become a top priority. Now a general consensus of enterprises, the competition between enterprises is essentially the enterprise brand competition, promote enterprise's brand value, completes the brand strategy to improve the competitiveness of enterprises is one of the essential factors.Based on the combination of theory with case analysis method, different from the Angle of private enterprise of brand positioning and brand strategy, analyzes the problems faced by private enterprise of the form and the problems and solutions, and ultimately selected for different levels of strategy, and then give the private enterprise strategy of brand positioning and the research provides a reference.The letter divides into three parts, the first part of this enterprise and brand strategy: the second part of a concrete analysis of private enterprise and brand strategy: the third part of the above problems are summarized and realistic meaning of the comments and Suggestions.。

Topic: OpenGL basic knowledge and textureAbstract: OpenGL is defined as "a software interface of graphics hardware". In essence, it is a 3D graphics and model base, have a high degree of portability, and has a very fast speed. The use of OpenGL, 3D images to create elegant and beautiful, and has a very good visual quality. In the application of 3D in the market, in addition to the rendering of point, line and triangle, the surface color by calculating the color value, through the interpolation operation to simulate the lighting effect, in order to achieve more realistic effects, there is a shortcut, is texture mapping (texture mapping), a small amount of texture files can increase effect exciting for 3D rendering。
