# 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.
