Point Product

传回 vector1 和 vector2 的点积 (Point Product)。复制 // Calculates the Dot Product of two Vectors.

例句：

If I take the dot product But now, what does it mean that the dot product between OP and A is zero ?

如果我用 OP ·A 我就得到了，那么 OP 和 A 的点积是 0 代表了什么呢？

It's the dot product between the normal vector of a plane and the vector along the line .

这是平面法向量，和沿直线向量的点积。

Also note that you can calculate the dot product only if the two vectors have the same number of components .

另外请注意，只有当两个矢量的组件数相同时，才能计算点积。

But , you will see that notation somehow helps to make it more straightforward So , what is dot product ?

但是你会发现，这个方法会让问题更简单，那么，什么是 “点积 ”？

Let us take a down-to-earth example of a dot product .

举一个点积的，现实例子。

Note that the dot product of two vectors is a number , not another vector .

请注意，两个矢量的点积是数字，而不是另一个矢量。

I'm going to teach you -- - just like with the dot product-- two methods .

跟点积一样 -，我会教你们 -，两种方法。

Returns the dot product of two quaternions .

返回两个四元数的点积。

What we will do is just, at every point along the curve , the dot product between the vector field and the normal vector .

我们要做的是，沿着曲线的每一点上，取向量场和法向量的点积。

Returns the dot product of two vectors.

返回两个向量的点积

The dot product of the two quaternions .

两个四元数的点积。

The dot product, being the product of three scalars, is a scalar .

点积是三个标量的乘积，所以是个标量。

The dot product of the specified vectors .

指定的向量的点积。

There is another way that you can find the dot product .

另一个定义，点积的方法。

And let's now talk about dot products .

现在我们讲讲点积。

OK, so now if we have a dot product that's zero, that tells us that these two guys are perpendicular .

所以我们现在有了一个点积为，这告诉我们两者是垂直的。

We can just find the angle using dot product So , how would we do that?

可以直接用点积来，找到这个角的大小，那么，怎么找呢？
