3d的空间轨迹代码 是在对话框下运行的-3d space trajectory code

仿真日月地运行，采用GDI+技术，动态显示运行过程，并绘制运动轨迹。-Sun and the moon to run the simulation, the use of GDI+ technology, the dynamic display during operation, and draw the trajectory.

程序中设置了两个计时器，分别用以控制曲线的绘制和进度条。程序运行后，两个互相“缠绕”的小球绘制出曲线轨迹，而进度条也随着曲线绘制的进度同步增长。另外，该程序还实现了鼠标键对动画的简单控制：左键暂停，右键重新绘制动画。-The procedures set two timers, respectively, to control the drawing of the curve and the progress bar. The program is running, the two wound

c#结合opengl编写的太阳地球月球运行轨迹动画，运用纹理，光照，材质等，非常有价值。-c# opengl prepared by combining the trajectory of the sun earth moon animation, the use of texture, light, material, etc., is very valuable.
