Summary

Function: float llVecDist( vector vec_a, vector vec_b );

Returns a float that is the undirected nonnegative distance between vec_a and vec_b.

• vector vec_a Any valid vector
• vector vec_b Any valid vector

Examples

<lsl> default {

   state_entry()
   {
       vector input_1 = <1.0,2.0,3.0>;
       vector input_2 = <3.0,2.0,1.0>;
       llOwnerSay("The distance between " + (string) input_1 +
           " and " + (string) input_2 + " is: "+(string)llVecDist(input_1, input_2) );
   }

}

</lsl>

Notes

  • Mathematically equivalent to:
    • llVecMag( vec_a - vec_b )
    • llSqrt( (vec_b.x - vec_a.x) * (vec_b.x - vec_a.x) + (vec_b.y - vec_a.y) * (vec_b.y - vec_a.y) + (vec_b.z - vec_a.z) * (vec_b.z - vec_a.z) )
