说明：  绘制1个沿圆形轨道运动的红色球体和1个沿椭圆轨道运动的蓝色球体。两个轨道圆心重合，圆的半径为100，椭圆的长短轴半径分别为200和100，运动方向为顺时针
(Draw a circular orbital motion along the red sphere and a movement along the elliptical orbit of the blue sphere. Center two tracks overlap, the circle Radius of 100, the radius of the ellipse minor axis of 200 and 100, respectively, for the clockwise direction of motion)
