在本範例中,我們將示範如何展示Polygon 絕對高,說明如下:
<範例>
var earth_ = null;
function documentLoad() { SuperGIS.Initialize("/ServerGate/", function () { SuperGIS.ServerEarth.Initialize(InitEarth); }); }
function InitEarth() { var pBody = new SuperGIS.Windows.HTMLContainer(document.body);
var sHost = location.href; var idx = sHost.indexOf("/", 8); if (idx >= 0) sHost = sHost.substring(0, idx); CreateHTML5Earth(pBody, function (pEarth) { EarthLoaded(pEarth); });
function EarthLoaded(pEarth) { earth_ = pEarth; pEarth.Scene.BackgroundColor = pEarth.CreateColor(0, 0, 0, 1); pEarth.SetupSystem(true, s_WGS84); pEarth.SetupSkin(pEarth.CreateEnvelope(-180, 180, -90, 90, s_WGS84), ""); pEarth.MajorGraticule.Visible = false; pEarth.MinorGraticule.Visible = false;
Dtm = new SuperGIS.DTMLayer("http://203.66.168.227/TGOS3D_WMTS/World/SimpleWMTS_GLOBE_W_D.aspx?apikey=mcXodoZFWJaUJRFS5H3gCec83a570/QupBX5ROqlSmu9vZW61YOYMe86Om9zQ2g2pVSGtjfLi5gex++mKHMFNK95UFUwZD3TtpSdH73WhL5KMv0WZVPMe5rB4KiLpaRrReusEFx+W10=&appid=BHvpiOJ5Wp41CsxemFMNWQ==", pEarth, { layer: 'Map' }, null);
// 指定圖磚服務的 WMTS 網址, 欲加入的圖層名稱及 callback function 名稱 Tile = new SuperGIS.TileLayer("http://203.66.168.227/TGOS3D_WMTS/World/SimpleWMTS_GLOBE_W.aspx?apikey=mcXodoZFWJaUJRFS5H3gCec83a570/QupBX5ROqlSmu9vZW61YOYMe86Om9zQ2g2pVSGtjfLi5gex++mKHMFNK95UFUwZD3TtpSdH73WhL5KMv0WZVPMe5rB4KiLpaRrReusEFx+W10=&appid=BHvpiOJ5Wp41CsxemFMNWQ==", pEarth, { layer: 'Map' }, null);
// 指定向量磚服務的 WMTS 網址, 欲加入的圖層名稱, 及 callback function 名稱 VLayer = new SuperGIS.VectorLayer(getDataServicePath() + 'project_block/SimpleWMTS.aspx', pEarth, { layer: '土地使用分區' }, LanduseFinish);
pEarth.SetViewpoint(120.656, 24.160, 500, 0, 50, true); }
// 在 callback 中設定每個 feature 的符號樣式 function LanduseFinish(array) { var rv = 128, gv = 255, bv = 128; for (var i = 0; i < array.length; i++) { var mark = array[i]; var fc = earth_.CreateColor(rv / 255.0, gv / 255.0, bv / 255.0, 128 / 255.0); mark.ReplaceZ = 100; // 設定高程 (公尺) mark.DDDSymbol = earth_.CreateSimpleDDDFillSymbol(earth_.CreateModelMaterial(0, fc), null);
// ExtrudeSymbol 是拔高面的 Symbol 樣式, 只要有設定, 就會畫出拔高面 mark.ExtrudeSymbol = earth_.CreateSimpleDDDFillSymbol(earth_.CreateModelMaterial(0, fc), null); mark.AltitudeMode = SuperGIS.DDDEarth.AltitudeMode.Absolute; } } }
