Vector3 class

A vector with three components.

The Vector3 type exposes the following members:

Constructor	Description
`__init__(self, x, y, z)`	Initializes a new instance of the `Vector3` struct.
`__init__(self, vec)`	Initializes a new instance of the `Vector3` struct.
`__init__(self, v)`	Initializes a new instance of the `Vector3` struct.
`__init__(self, vec4)`	Initializes a new instance of the `Vector3` struct.
`__init__(self)`	Constructs a new instance of Vector3

Property	Description
length2	Gets the square of the length.
length	Gets the length of this vector.
zero	Gets unit vector (0, 0, 0)
one	Gets unit vector (1, 1, 1)
unit_x	Gets unit vector (1, 0, 0)
unit_y	Gets unit vector (0, 1, 0)
unit_z	Gets unit vector (0, 0, 1)
x	The x component.
y	The y component.
z	The z component.

Name	Description

Method	Description
`angle_between(self, dir, up)`	Calculate the inner angle between two direction Two direction can be non-normalized vectors
`angle_between(self, dir)`	Calculate the inner angle between two direction Two direction can be non-normalized vectors
`dot(self, rhs)`	Gets the dot product of two vectors
`normalize(self)`	Normalizes this instance.
`sin(self)`	Calculates sine on each component
`cos(self)`	Calculates cosine on each component
`cross(self, rhs)`	Cross product of two vectors
`set(self, new_x, new_y, new_z)`	Sets the x/y/z component in one call.
`compare_to(self, other)`	Compare current vector to another instance.
