Access: Nodes > Math > Length
The Length node takes an input vector and outputs the length (or magnitude) of the vector. The following formula is used to calculate the length of the vector:
Where 
is the vector [xy z w] and 
is the length of the vector.
The output is a vector and the alpha channel always has a value of 1.0. Therefore the output is in the format:
[
1 ]
Tip: For more information on the vector length equation solution, see the Vector Magnitude Calculator by OnlineMSchool.

Length Node Properties
|
R checkbox |
When checked, the red component is included in the length calculation. |
|
G checkbox |
When checked, the green component is included in the length calculation. |
|
B checkbox |
When checked, the blue component is included in the length calculation. |
|
