Dot Product
Menu Path : Operator > Math > Vector
The Dot Product uniform Operator performs a dot-product between two input vectors and outputs the result.
This operator is useful for numerous purposes which include:
- To compute the squared length of a given vector. To do this, connect the same vector to both input ports.
- To determine whether two normalized vectors point in the same direction. This returns 1.0 if the vectors point in the same direction, 0.0 if they are perpendicular, and -1.0 if they point in opposite directions.
- To project a vector A on a normalized vector B and return its projected length along B.
Operator properties
| Input | Type | Description |
|---|---|---|
| A | Configurable | The first vector of the dot product. |
| B | Configurable | The second vector of the dot product. |
| Output | Type | Description |
|---|---|---|
| Output | float | The result of the dot product. The Type changes to match the type of A and B. |
