点 (结构式) 在三维坐标上平移，Python实现

没有废话，直接上代码
记得要声明Point类

#结构式在三维坐标上平移，默认将下标为0的点移动到某个位置，其它点同样平移
#这个listPoint可能只是一个片段
@staticmethod
def structureMoveTo(listPoint, moveToPoint, index = 0):
    if 0 <= index < len(listPoint):
        point = listPoint[index]
    
    #两个点的差别
    deltaX = moveToPoint.x - point.x
    deltaY = moveToPoint.y - point.y
    deltaZ = moveToPoint.z - point.z
    
    listPoint2 = []
    for p in listPoint:
        listPoint2.append(Point(p.x + deltaX, p.y + deltaY, p.z + deltaZ))
    return listPoint2
