3D Mesh from cloud of points

It’s better to compare vectors with some tolerance, as you can’t get the same exact result with calculation by the reason of precision.
I took it from here:

Comparing two vectors

Well, you can use Vector3.equals() if you want to check for equality. However, if you need more flexibility because of floating point inaccuracies, you can monkey-path Vector3 with your own equals method like so: equals( v, epsilon = Number.EPSILON ) { return ( ( Math.abs( v.x - this.x ) < epsilon ) && ( Math.abs( v.y - this.y ) < epsilon ) && ( Math.abs( v.z - this.z ) < epsilon ) ); }

And used something very similar in this SO answer before:
