Bagaimana cara membuat peta ubin segi enam Google Maps API v3, sebaiknya berbasis koordinat?

http://econym.org.uk/gmap/example_eshapes.htm memiliki Google Maps Contoh API v2 tentang cara menyusun segi enam, meskipun penerapannya berskala sulit: ia memiliki segi enam tengah, lalu enam segi enam yang berdekatan dengan arah yang sesuai, lalu (dalam kuasi-rekursi) tiga segi enam yang berdekatan dengan salah satu segi enam yang berdekatan dengan segi enam asli. Dan itu memiliki batas yang bagus dengan isian transparan.

Bagaimana saya bisa membuat efek serupa, tetapi lebih disukai dengan ubin sehingga saya menentukan (tanpa gundukan rekursi) bahwa saya ingin ubin enam segi enam di sebelah timur titik asal dan empat segi enam 60 utara timur dari ubin enam segi enam ke timur ?

Saya mencari sesuatu yang berbasis koordinat dan sebaiknya yang sederhana. Saya telah melihat sumber untuk http://www.rootmetrics.com/check-coverage/ dan berfungsi, tetapi kode tersebut digabungkan dengan halaman spesifiknya, markup, dll., jadi meniru kodenya akan memerlukan sedikit penguraian.

Contoh berikut menunjukkan cara merender kisi segi enam horizontal:

function initialize() {
    var mapOptions = {
        zoom: 7,
        mapTypeId: google.maps.MapTypeId.TERRAIN
    };

    var map = new google.maps.Map(document.getElementById('map-canvas'),mapOptions);
    var startPosition = new google.maps.LatLng(33.748589, -84.390392);  //Atlanta, GA, USA 
    var radius = 40 * 1000; //radius in meters
    drawHorizontalHexagonGrid(map,startPosition,radius,6);
    map.setCenter(startPosition);
}

function drawHorizontalHexagonGrid(map,startPosition,radius,count){
    var curPos = startPosition;
    var width = radius * 2 * Math.sqrt(3)/2 ; 
    for(var i = 0;i < count; i++){
        drawHorizontalHexagon(map,curPos,radius);
        curPos = google.maps.geometry.spherical.computeOffset(curPos, width,90);   
    }
}

function drawHorizontalHexagon(map,position,radius){
    var coordinates = [];
    for(var angle= 0;angle < 360; angle+=60) {
       coordinates.push(google.maps.geometry.spherical.computeOffset(position, radius, angle));    
    }
  
    // Construct the polygon.
    var polygon = new google.maps.Polygon({
        paths: coordinates,
        strokeColor: '#FF0000',
        strokeOpacity: 0.8,
        strokeWeight: 2,
        fillColor: '#FF0000',
        fillOpacity: 0.35
    });
    polygon.setMap(map);
    map.setCenter(position);
}

google.maps.event.addDomListener(window, 'load', initialize);

Saya mem-porting eshapes (dan http://econym.org.uk/gmap/example_eshapes.htm) ke Google Maps API v3

Tidak jelas apakah itu yang Anda cari, tapi sepertinya itu dari judul pertanyaan Anda.

cuplikan kode:

var map = null;

function initMap() {
  var myOptions = {
    zoom: 8,
    center: new google.maps.LatLng(43, -79.5),
    mapTypeControl: true,
    mapTypeControlOptions: {
      style: google.maps.MapTypeControlStyle.DROPDOWN_MENU
    },
    navigationControl: true,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  }
  map = new google.maps.Map(document.getElementById("map"),
    myOptions);

  // === Hexagonal grid ===
  var point = new google.maps.LatLng(42, -78.8);
  map.setCenter(point);
  var hex1 = google.maps.Polygon.RegularPoly(point, 25000, 6, 90, "#000000", 1, 1, "#00ff00", 0.5);
  hex1.setMap(map);
  var d = 2 * 25000 * Math.cos(Math.PI / 6);
  var hex30 = google.maps.Polygon.RegularPoly(EOffsetBearing(point, d, 30), 25000, 6, 90, "#000000", 1, 1, "#00ffff", 0.5);
  hex30.setMap(map);

  hex90.setMap(map);
  var hex150 = google.maps.Polygon.RegularPoly(EOffsetBearing(point, d, 150), 25000, 6, 90, "#000000", 1, 1, "#00ffff", 0.5);

  hex150_2.setMap(map);
  var hex90_2 = google.maps.Polygon.RegularPoly(EOffsetBearing(EOffsetBearing(point, d, 90), d, 90), 25000, 6, 90, "#000000", 1, 1, "#00ff00", 0.5);
