循环点

螺旋线是一种造型元素，这种元素的特点是：任何一个点都有与其相对应的循环点，每个循环点处于不同的时空位置，并且总是不重复的周期性循环着。

The helix is an element of modeling , the feature of this element is : every point has its corresponding cyclic point , and every cyclic point is located in different time and space domain , and it circulates in different orbits periodically .
