[Papervision3D] Distance between two 3D points

[John Grden]

sorry, heres the entire method:

public function distanceTo( obj:DisplayObject3D ):Number
    {
        var x :Number = this.x - obj.x;
        var y :Number = this.y - obj.y;
        var z :Number = this.z - obj.z;

        return Math.sqrt( x*x + y*y + z*z );
    }

I'm assuming you could use the same logic
