What is the normal vector?───向量又是什么呢？

Well, you know the normal vector.───那么當然知道它的法向量。

Why would we ever know a normal vector?───為什么我們會知道法向量？

Let me show you a picture. The rule is if I walk along C with S to my left then the normal vector is pointing up for me.───給你們看張圖片，“相容”就是，如果我沿著C走，而且S在左邊，法向量就是朝上的。

If you know what a cylinder looks like, you probably can see that the normal vector sticks straight out of it horizontally.───如果大家知道圓柱面是什么樣的，那么就可以想象到，其法向量水平地指向外面。

Just to reiterate what I said, positively here means, because we are going counterclockwise, the normal vector points out of the region.───再說一遍，這里“正的”意味著。。。，由于是逆時針走向，法向量指向區域外側的。

Hopefully, you can see that if I take a normal vector to the sphere it is actually pointing radially out away from the origin.───我希望大家能夠了解，如果我將法向量平移至球面，那么它將以原點為心向外放射。

To find the surface element together with a normal vector, I would just take the cross-product between these guys.───為了找到帶法向量的面元，我就取這兩個的叉積。

The revision of the image gradient is to revolve it to the reverse direction of the normal vector's projection on the image plane.───圖像梯度修正是將圖像梯度方向旋轉到盡量與法向量在圖像平面的投影反向一致的方向上。

In this paper, the algorithm in which normal vector of vertex is used to control simplifying error obtains good result on briefness, simplifying velocity and quality.

This paper researches and realizes two algorithms of point clouds segmentation-the direct segmentation method based on planarity and the surface segmentation method based on logarithmic normal vector.

The convention in the divergence theorem is that we orient the surface with a normal vector pointing always outwards.

Applying the nature about normal vector and independent random vector, the sampling distribution of single effect in variance analysis can be directly gotten.

There's no way to choose consistently a normal vector for the Mobius strip So, that's what we call a non-orientable surface.

According to the calculation theory, the tangent vector, the velocity and the normal vector on a given point of the circle of tool nose are coplanar.

Let me re-explain quickly how I got a normal vector for the cylinder.

OK, and that's going to be the normal vector to the surface or to the tangent plane.

The other kind of feature points are those where the absolute value of the scalar product of its normal vector and the view vector is less than a threshold.
