Dot proc (vector)

Format

A.Dot(B)

Args

B: The other vector.

Returns

The dot product of the two vectors.

The dot product of two vectors is determined by multiplying each component in the first vector by its matching component in the second, and adding those multiples together. For instance in a 2D vector, the dot product of A and B is:

dot = A.x * B.x + A.y * B.y

The dot product is equal to the product of the magnitude of the two vectors and the cosine of the angle between them.

dot = A.size * B.size * cos(angle)
