Vector binary operations
Use these syntaxes to perform additional vector math calculations:
Note: JavaScript does not support these operations for vector objects. In JavaScript, you must write
the code to perform the vector math calculations using the vectors' x, y, and z coordinates.

Description
Normalizes the vector by modifying it into a unit vector of
length 1. This is done by dividing each component of the
vector by the vector's original length. That original length
is the square root of the sum of the squares of each
component.
Returns a normalized version of the vector.
Returns the dot (inner) product of the first vector and the
second vector (
vector2
length, the result is the cosine of the angle between the
two vectors.
Returns the angle between
degrees.
Returns a vector perpendicular to the original vector and
to .
vector2
Returns the distance between
these vectors represent positions in the 3D world, this is
the distance between them.
A copy of the vector.
Description
Returns a new vector equaling
equaling 1 through 3.
Returns a new vector equaling
for
vector1 -vector2 x
Returns the product of the two vectors.
Not supported.
Returns a new vector equaling
