篇一：空中天使 A Sky Angel
A Sky Angel
In 1978, I became a flight attendant for a major airline. Earning my wings was the culmination of a childhood dream that I had set for myself after my first plane ride at the age of five. Like so many others before me, I fell in love with the romance of airplanes, adventure and helping others.
I have flown hundreds of flights since graduation, but one stands out among the many.
We were flying from Los Angeles to Washington, D.C, when I answered a lavatory call light in the coach cabin. There I found a young mother struggling with her infant. Everything was a mess, to say the least, and the mother, who was near hysterics, told me she had no more diapers or other clothing onboard the aircraft.
Through her tears, she informed me that they had missed their flight the previous night in Los Angeles and because she had very little money, she and her son had spent the night on the airport floor. Since she hadn't expected to miss the flight, she was forced to use up most of her supplies and whatever money she had to feed them.
With the saddest eyes I have ever seen she continued. She told me she was on her way to New Hampshire to deliver her son to the family that was adopting him. She could no longer support the two of them.
As she stood in front of me, crying, holding her beautiful son, I could see the despair and hopelessness on her face. And, as a mother of three beautiful daughters, I could feel her pain.
I immediately rang the flight attendant call button and asked for assistance from the other flight attendants. They brought cloth towels from first class to assist in cleaning up both mom and the infant. I ran and got my suitcase; because this woman and I were about the same size, I gave her a sweater and a pair of pants I had brought for my layover. Then I asked several families if they could spare extra diapers, formula and clothes for the child. After the young mother and her son had changed their clothes and the baby had gone to sleep, I sat with her, holding her hand, trying to provide some support and comfort for the remainder of the flight.
Once we landed, I walked them to their next flight, which would take them to their final destination; separation. I briefed the gate agent and the new flight attendant crew on the situation and asked them to give her special attention.
With tears in my eyes I gave her a hug and told her, You have shown me the true meaning of courage and a mother's love. I will never forget you.
As she thanked me for all I had done she said softly, You're not the flight attendant, you're a sky angel. Touching my flight attendant wings, she continued, And those are your angel wings.
With those words she turned and walked down the jetway, her child in her arms, and boarded the plane for New Hampshire.
Though I am no longer a flight attendant, my angel wings are still on prominent display in my office. And each time I see them, I am reminded of that young woman, her infant son and the gift that she gave me on that special day - that we truly are all spiritual beings traveling in human form.

篇三：OpenGL实验一
学院 班 学号 姓名：曲绍霖 教师评定： 实验一 基本三维图形的建模及基本交互
一、实验目的
1 掌握OpenGL的三维图形绘制方法
2 掌握Visual C++环境下的OpenGL图形开发
二、实验要求
在Windows平台上用VC++结合GLUT做实验，要求掌握结合VC++和OpenGL的基本图形(四面体、六面体、圆柱、圆锥等)建模及编程技能，以及图形学的基本原理，实验完成后要求根据自己的成果撰写一份实验报告。
1 基本三维几何图形（四面体、六面体、圆柱、球等）的建模及基本的交互 2 人机交互(图形的基本变换，如旋转、平移、尺度缩放及橡皮筋技术等)
三、实验环境
操作系统：Windows xp
开发环境：VC++6.0以及GLUT
图形交互设备：鼠标和键盘
四、实验内容
1 GLUT在VC++6.0环境下的正确配置
下载GLUT包，解压后，文件夹中有dll，lib，h文件，将glut32.dll，glut.dll复制到C:\WINDOWS\system32下，将glut32.lib, glut.lib放到C:\Program Files\Microsoft Visual Studio\VC98\Lib(即安装VC++6.0的目录)，将glut.h复制到C:\ProgramFiles\Microsoft Visual Studio\VC98\Include\GL
2对基本图形（四面体，六面体，圆柱，球等）的建模及基本交互。 a 在上述四种图形的中选择两种及两种以上进行建模或者组合他们产生新的对象。
b 基本的交互包括：利用鼠标、键盘实现图像的交互(主要实现物体的浏览)
五、存在的问题和感想
虽然开始对OpenGL的编程不是很了解，但是因为对VC++的编程还是有比较深的了解，所以对OpenGL的函数的运用会查阅MSDN来学习如何使用，然后再参考了一下网上的代码和实验给出的例子，基本了解是如何进行OpenGL的编程，一开始觉得OpenGL的编程跟一般的VC++编程有很大的区别，可能很难入门，但是后来，认真研究了一下实验给出的例子，还是很顺利地读懂了。也对OpenGl的建模，光照等有
了一定的理解，后来，再运用一下网上相关的代码，加上自己理解的修改，就顺利完成了实验，开始觉得OpenGL的编程很难，就对实验抱着一个厌恶的感觉，但是后来自己做出实验的时候，就开始觉得OpenGL是十分有趣的。
实现代码：
#include

篇五：OpenGL实验二
学院 专业 学号 姓名：曲绍霖 教师评定： 实验二 光照模型的实现
一、实验目的
掌握OpenGL的光照及材质效果设置方法
二、实验要求
在Windows平台上用VC++结合GLUT做实验，要求掌握结合VC++和OpenGL的光照模型的理解及实现，实验完成后要求根据自己的成果撰写一份实验报告。
三、实验环境
操作系统：Windows xp
开发环境：VC++6.0以及GLUT
图形交互设备：鼠标和键盘
四、实验内容
在实验一的基础上理解并实现添加各种光（环境光，发散光，镜面光，聚光），使效果更逼真以接近实际环境。
1、打开灯光，设置灯光的位置、方向、类别、颜色和衰减，并改变其值，观察效果的变化。
2、实现旋转和移动灯光。
3、设置材质，了解材质和光照如何相互影响。
五、存在的问题和感想
在教科书的基础上增加光照的效果，难度不算太大，，在光照的效果中，用户可以编辑两种材质，经过光源的添加后，使得材质的形象更突出，用户可以自由移动光源位置达到想要的效果，这次实验也是对OpenGL学习加深了认识
六、实现代码
#include
#include
#include
#include
static int xRot=0;
static int yRot=0;
int iModel=1;
void init(void){
// 定义光源，它是一种白色的光源
glLightModelfv(GL_LIGHT_MODEL_AMBIENT,lmodel_ambient);
}

七、运行结果：
用键盘的上下左右来控制光源移动以看到有光反射出来的效果。
光照效果1:有环境光反射，漫反射，无镜面反射，发射光，低光泽度
