Let's break the name down. The "normal" is a vector perpendicular to a surface, which we can use to calculate lighting.
首先我们从名字上开始分析,所谓“法线”指的是垂直于平面的向量,我们使用这个来计算光照。
OK, and that's going to be the normal vector to the surface or to the tangent plane.
这就是切平面的,或者说这个曲面的法向量。
S if we have a closed surface with a normal vector pointing outwards, and we want to find a flux integral for it, well, we can replace that with a triple integral.
的法向量似乎是指向外部。,And, the,normal, vector, to,s, seems, to, be, pointing, out wards, everywhere。,如果我们有一个法向量指向外部的封闭曲面,并且我们要求出它的一个通量积分,那么我们可以用一个三重积分来代替这个通量积分。
You will get some sort of mesh grid on your surface and you will look at a little parallelogram that is an elementary piece of that mesh and figure out what is its area and normal vector.
在曲面上做一些网格,你会看到一个网上的每一小块儿,都是小的平行四边形,我们要弄清楚它的面积和法向量是什么。
You can remember, if it helps you, that if a surface is to your right then the normal vector will go down.
你也可以这样记,如果曲面在你的右边,那么法向量就向下。
Well, the question we have now is what is the area of this little piece of surface and what is its normal vector?
现在的问题是,曲面上这一小块儿的面积是什么,及其法向量是什么?
Ok, if we look at it near here, if we walk along this way, the surface is to our right.so, we should actually be flipping things upside down. The normal vector should be going down.
我们看看这里,如果我们沿着这条路走,曲面就在我们的右边,我们应该是把它颠倒一下,这个法向量也应该向下。
The convention in the divergence theorem is that we orient the surface with a normal vector pointing always outwards.
在散度定理中的约定是,将曲面的定向取为外法线的方向。
All right, it has the same normal vector as the surface.
它和曲面有相同的法向量。
To find the surface element together with a normal vector, I would just take the cross-product between these guys.
为了找到带法向量的面元,我就取这两个的叉积。
There's no way to choose consistently a normal vector for the Mobius strip So, that's what we call a non-orientable surface.
为Mobius带选一个始终如一的的法向量是不可能的,这就是所谓的不可定向的曲面。
So if you have some region of space S and you call its boundary surface S and you let n be the normal vector that goes out of the region R.
如果存在一些区域空间,边界为曲面,定义n为指向区域R外的法向量。
The normal vector of each data point is calculated without reconstructing surface, and then realizing radius compensation with probe radius by going along normal vector.
在不需要重建曲面模型的情况下,找到每一个数据点的法矢,在该法矢方向上补偿一个球头半径实现了测头半径的三维补偿。
