unit vector-unitize vector.向量单位化。 就是向量单位长度化为1。 单位向量X Y Z,这个就没啥好说的 amplitude-set the amplitude (length) of vector. 修改指定向量(Vector)的向量长度为指定数值. angle-compute the angle between two vectors.
The vector vec c , directed along the internal bisector of the angle between the vectors vec a = 7 hati - 4 hatj - 4hatk and vecb = -2hati - hatj + 2 hatk

The following is the formula for calculating the angle between two vectors. Cosθ = a→.b→/ |a|.|b| Cosθ = a1.b1 + a2.b2 + a3.b3 / √a12+ a22+a32 . √b12+b22+b32 . Conclusion The vector projection can be divided into two types: the scalar projection, which indicates the...

The angle between two vectors in 3D depends on their relation to each other (and does not depend on your viewpoint, or the coordinates frame you are using).Of course, when a 2D picture shows a 3D scene the angles in the picture very much depend on the viewpoint. ...
