本程序实现以下功能： 1.绘制茶壶(T) 2.添加光照(T) 3.添加纹理(T) 4.鼠标左键控制茶壶旋转(T) 操作步骤：按鼠标左键茶壶旋转，按一次旋转30°。 5.鼠标右键控制茶壶平移(T) 操作步骤：按鼠标右键茶壶向右移动，每次移动0.5厘米 6.键盘控制茶壶纹理的变化(T) 操作步骤：按键盘的 w 和 s 键实现纹理的改变 7.键盘方向键控制camera的前进后退，左移和后移 (T) 操作步骤：按键盘的四个方向键实现茶壶四种方向的移动 8.实现水壶的退出-This procedure to achieve the following functions: 1. Drawing teapot (T) 2. Add light (T) 3. Add texture (T) 4. Teapot rotating the left mouse button to control (T) steps: Click the left mouse button rotate the pot by a rotation 30 °. 5. Teapot with the right mouse button to control translation (T) steps: Click the right mouse button to the right teapot mobile, each mobile 0.5 centimeters 6. Teapot keyboard to control the changes in texture (T) steps: click the " w " and" s" key changes to achieve texture 7. the keyboard arrow keys to control the forward camera back, the left and post-shift (T) steps: the four keyboard arrow keys to achieve the direction of movement of the four teapot 8. to achieve water out of the

翻译  maninwest@Codeforge 作者:Vasily Tserekh@CodeProject这是个  3D 太阳系，使用 OpenGL 和 C# 实现。我尽量让它简单。它包含行星、卫星、太阳月亮和其他星星。我使用了 TAO命名空间，它是在 OpenGL dll 和 .NET Framework 之间的互操作。我也用了 Shadowengine - 一个我自己开发的小图形框架。使用它，我可以省去加载图形和初始化图形上下文的代码编写工作。3D 编程员眼中的太阳系3D 编程员需要将宇宙、轨道、星星等实体在程序设计环境中进行转化。宇宙是一个黑色背景，可以使用 OpenGL 的函数  Gl.glClearColor(0, 0, 0, 1);//red green blue alpha 。至于星星，可以使用点来替代。可以使用 OpenGL 处理绘制点的基元。你也可使用随机函数生成大量点，只要确保它们不在太阳系中即可。行星是有底纹的球体。它们有自己的轨道和旋转轴。你得使用 变量跟踪并更新，因为它们随着时间改变。如果不想使用3D max 制作球体，可以使用 OpenGL 二次曲线。卫星和行星一样，只是不饶太阳而是绕行星转。使用代码项目中包含对 ShadowEngine和 TAO.OpenGL 的引用.  项目类有： Camara.cs典型的 FPS 相机。鼠标以屏幕中间为中心。用户移动鼠标时，会计算离开始点的  delta X 和 Delta Y 。这些 Delta X 和 Delta Y 被转化成角度当你向前/向后移动相机时，相机会移动到角度指的方向。
