I've already tried searching several different things on Google. Doesn't seem like I'm able to find anything. Thought I might as well upload a question to Stack Overflow.
Thanks!

The distance formula states that the distance between two points in xyz-space is the square root of the sum of the squares of the differences between corresponding coordinates. That is, given P1 = (x1,y1,z1) and P2 = (x2,y2,z2), the distance between P1 and P2 is given by d(P1,P2) = (x2 x1)2 + (y2 y1)2 + (z2 z1)2.
Where v1 and v2 are of type THREE.Vector3:
function distanceVector( v1, v2 )
{
var dx = v1.x - v2.x;
var dy = v1.y - v2.y;
var dz = v1.z - v2.z;
return Math.sqrt( dx * dx + dy * dy + dz * dz );
}
Update:
In the r74 release of three.js the method .distanceTo( v ) can be used.
