Elegant way the find the Vertices of a Cube

When i was "porting" the csg.js project to Java I've found some cute code which generated cube with selected center point and radius. (I know it's JS, but anyway)

// Construct an axis-aligned solid cuboid. Optional parameters are `center` and
// `radius`, which default to `[0, 0, 0]` and `[1, 1, 1]`. The radius can be
// specified using a single number or a list of three numbers, one for each axis.
// 
// Example code:
// 
//     var cube = CSG.cube({
//       center: [0, 0, 0],
//       radius: 1
//     });
CSG.cube = function(options) {
  options = options || {};
  var c = new CSG.Vector(options.center || [0, 0, 0]);
  var r = !options.radius ? [1, 1, 1] : options.radius.length ?
           options.radius : [options.radius, options.radius, options.radius];
  return CSG.fromPolygons([
    [[0, 4, 6, 2], [-1, 0, 0]],
    [[1, 3, 7, 5], [+1, 0, 0]],
    [[0, 1, 5, 4], [0, -1, 0]],
    [[2, 6, 7, 3], [0, +1, 0]],
    [[0, 2, 3, 1], [0, 0, -1]],
    [[4, 5, 7, 6], [0, 0, +1]]
  ].map(function(info) {
    return new CSG.Polygon(info[0].map(function(i) {
      var pos = new CSG.Vector(
        c.x + r[0] * (2 * !!(i & 1) - 1),
        c.y + r[1] * (2 * !!(i & 2) - 1),
        c.z + r[2] * (2 * !!(i & 4) - 1)
      );
      return new CSG.Vertex(pos, new CSG.Vector(info[1]));
    }));
  }));
};
