In line 109, the polyline element is started, and an initial point is drawn at the origin of the axis.
第 109行是polyline元素的起点，它与坐标轴的原点重合。
OK, we've seen about spheres and cylinders centered at the origin or centered on the z axis.
我们已经知道,中心在z轴的球体和圆柱体。
Therefore, the optimal solution is the farthest point on the polyhedron boundary from the axis' origin using the direction (1,-1) as a direction vector.
因此，优化解决方案是从轴的原点沿 (1,-1)方向作为方向向量指向多面体边界的最远点。
So, as you do with the x-axis in the Cartesian plane, you consider a particular cell to be the origin.
因此，在笛卡尔平面使用x轴时，考虑一个特定的细胞为原点。
Let's say that I want to go along this path from the origin, first along the X-axis to and then vertically to.
我想从原点开始沿着这条路径，首先沿x轴到，再垂直到。
A new design thought was proposed: the design technique which use the power output axis of tractor as the origin of power, furthermore, a Caragana cutting machine was primary designed.
最后本文提出了一种采伐机具新的设计思路，即以小四轮拖拉机动力输出轴为动力源的设计方法，并最终初步设计了一种柠条灌木林的采伐机具。
In practice this means that the object is drawn in the local origin, and it is looking along the positive Z axis.
事实上这意味着物体在局部坐标空间绘制，并且物体的正面朝向z轴正方向。//译者注：z轴正方向垂直屏幕指向观察者。
The origin is located on the axis at the point closest to the center of mass.
原点坐落在转轴上最靠近物体质心的一点。
Because that axis goes nearer the origin than the L2 link axis, all the elements that sit on it are superior to the members of the L2 axis.
由于去二级链接轴比接近原点，所有的元素，它坐在优于到了二级轴线的成员。
BTW the transformation matrix contains the local axis and local origin( if it is of any use2 you).
顺便说一句，变换矩阵包含本地轴及本地原点信息。
