How to sort an Array of vertices to make an unbroken 'sensible' geometry

This process is called triangulation, the thread here might help:

3D Mesh from cloud of points

Maybe you are right, In fact I was trying that at the time you sent your post. Would you mind to explain the reason of this code in the HTML part of the jsfiddle? <script> THREE.Vector3.prototype.equals = function( 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 ) ); } </script> Without this part the code does not work at all…

For concave geometry the results may not be exactly what you want without some tweaking in modeling software like Blender though.
