将复杂的三维图像投影在各个视图上，并将其合并在一起。便于找寻各种运动轨迹在各个投影方向的规律。-complex 3D image projection in all views, their combined. Easy to find various trajectories in all directions projection patterns.

本程序在WIN-TC环境下用C语言编写的，功能为完成机械结构运动的仿真，显示相应的轨迹。速度可以以常速运动，或慢速，或快速。-procedures in the WIN-TC environment using the C language, functions to complete mechanical structure of the simulation, show the corresponding trajectory. Speed can often speed to moveme

我艇和目标运动轨迹存放于TXT文件中，在MFC环境下画出我艇与目标的运动轨迹 TXT文件中有四列，前两列存放我艇的横、纵坐标，后两列存放目标的横、纵坐标-My boat and target trajectories stored in TXT file, in the MFC environment, I draw the trajectory of the target vessel

用matlab来制作卫星绕地球做周期运动的动画，改变卫星的角速度的初值，可以画出圆形，椭圆形，逃逸轨迹。-Using matlab to produce satellites orbiting the earth to do periodic motion animation, change the initial angular velocity of the satellite, you can draw round, oval, escape trajectory.

对一个小球的运动模拟，可以很好地模拟其轨迹，界面清晰，操作简单-A small ball of motion simulation that can simulate its trajectory, clear interface, easy operation
