Dot Product Node

Description

Returns the dot product, or scalar product, of the two input vectors A and B.

The dot product is a value equal to the magnitudes of the two vectors multiplied together and then multiplied by the cosine of the angle between them.

For normalized input vectors, the Dot Product node returns 1 if they point in exactly the same direction, -1 if they point in completely opposite directions and 0 if the vectors are perpendicular.
