Summary
Function: vector llVecNorm( vector vec );| 13 | Function ID |
| 0.0 | Forced Delay |
| 10.0 | Energy |
Returns the vector that is vec normalized (a unit vector sharing the same direction as vec).
| • vector | vec | – | Any valid vector |
If vec is a ZERO_VECTOR, than the value returned is a ZERO_VECTOR.

SVC-4711 | A | llVecNorm returns zero vector as result when input is below a certain magnitude |
Examples
<lsl> default {
state_entry()
{
vector input = <1.0,2.0,3.0>;
llSay(0,"The unit vector on "+(string)input+" is: "+(string)llVecNorm(input) );
}
}
</lsl>Notes
- Mathematically equivalent to:
- vec / llVecMag( vec )
- vec / llSqrt( vec.x * vec.x + vec.y * vec.y + vec.z * vec.z )
