float llVecDist(vector v1, vector v2)
This function
returns the distance between two positional
vectors. Here's a table of examples:
| v1 | v2 | return value |
| <0,0,0> | <1,0,0> | 1 |
| <0,0,0> | <0,0,-10> | 10 |
| <10,0,10> | <10,0,0> | 10 |
| <20,0,19> | <20,0,0> | 19 |
The equation for finding vector distance with components is
sqrt((x2-x1)^2 + (y2-y1)^2 + (z2-z1)^2).
or
llVecMag(v1 - v2);
//definition
vector VecNorm(vector v) {
return (v / VecMag(v));
}
float VecMag(vector v) {
return llSqrt(v.x*v.x + v.y*v.y + v.z*v.z);
}
float VecDist(vector a, vector b) {
return VecMag(a - b);
}
Compare with
llVecMag, and
llVecNorm.
