2.11 Vector Dot Product 前面讲到过向量可以与标量相乘。同样的,我们可以让向量和向量相乘。向量相乘有两种形式,一种是点积(或者叫点乘)dot product,一种是叉积cross product 在电子游戏编程中,处处都需要用到点积,在图形,模拟,以及AI等方面都很有用。点积公式是本书中为数不多的值得记忆的公式。如果你的脑子...
Dot/Cross Product 矢量点乘/叉乘 Dot Product是求向量点积,其实就是两个矢量xyz值乘积的和。 Cross Product在数学中又称外积、叉积,物理中称矢积、叉乘,是一种在向量空间中向量的二元运算。与点积不同,它的运算结果是一个向量而不是一个标量。并且两个向量的叉积与这两个向量所在平面垂直。 需要注意,任意向量...
提要211:向量外積(Vector Product 或Cross Product)之定義 兩向量之內積為純量,但兩向量的外積仍為向量,其定義如下。 向量之外積(Vector Product 或Cross Product) 若[ ] 3 2 1 , , a a a = a 、 [ ] 3 2 1 , , b b b = b ,則這兩個向量之外積是定義為: ...

A vector cross product is the product of two vectors that yields another vector. This product vector points in the direction perpendicular to the plane spanned by the other two vectors. There are many applications of the cross product, including torque a
