How do you create a sphere form 6 planes?

Hi all,

I have been attempting to create a sphere from 6 planes, so that I may later edit these planes to give the sphere a procedural generated surface (so as to create unique planets).

To take 6 planes and make them into a sphere, I have been using this code:

 public function MakeSphereFromPlanes()
     {
         var positionArr : Vector3[] = [
             new Vector3(0,this.radius,0),
             new Vector3(0,-this.radius,0),
             new Vector3(0,0,this.radius),
             new Vector3(0,0,-this.radius),
             new Vector3(this.radius,0,0),
             new Vector3(-this.radius,0,0)
         ];
 
         var rotationArr : Vector3[] = [
             Vector3.zero,
             Vector3.zero,
             new Vector3(90,0,0),
             new Vector3(90,0,0),
             new Vector3(0,0,90),
             new Vector3(0,0,90)
         ];
 
         for(var p : int = 0;p<6;p++)
         {
             //make 6 planes for the sphere in this loop
             var newPlane : GameObject = GameObject.CreatePrimitive(PrimitiveType.Plane);
             newPlane.transform.localScale = Vector3(this.radius,this.radius,this.radius);
             newPlane.transform.SetParent(this.gameObject.transform);
             newPlane.transform.position = positionArr[p];
             newPlane.transform.eulerAngles = rotationArr[p];
 
             var vertices : Vector3[] = newPlane.GetComponent(MeshFilter).mesh.vertices;
 
             for (var i = 0; i < vertices.Length; i++)
             {
                 vertices[i] = vertices[i].normalized * this.radius;         
             }
             newPlane.GetComponent(MeshFilter).mesh.vertices = vertices;
             newPlane.GetComponent(MeshFilter).mesh.RecalculateNormals();
             newPlane.GetComponent(MeshFilter).mesh.RecalculateBounds();
         }

   }

The issue I am running into is that this code seems to produce this:
