Question

SuperMap iClient3D for WebGL加载iServer发布的影像服务（imageservice），参考了博客（https://blog.csdn.net/supermapsupport/article/details/121649183），目前是仅支持4326或者4490的地理坐标系么？目前尝试3857坐标系在对应地理位置看不到出图。

【问题原因】代码问题 【解决办法】 let wmtsImageryProvider= new Cesium.UrlTemplateImageryProvider({ url: 'http://120.46.22.67:8090/iserver/services/imageservice-cdyxtest0623/restjsr/collections/image06231627/tile.png?z={level}&x={x}&y={y}&transparent=true', // url:"http://localhost:8090/iserver/services/imageservice-test11/restjsr/collections/lala/tile.png?z={level}&x={x}&y={y}&transparent=true", tileWidth:256, tileHeight:256, minimumLevel:0, maximumLevel:23, tilingScheme: new Cesium.WebMercatorTilingScheme({ ellipsoid: Cesium.Ellipsoid.WGS84, numberOfLevelZeroTilesX:1, numberOfLevelZeroTilesY:1, rectangleSouthwestInMeters:new Cesium.Cartesian2(-20037508.34,-20048966.1), rectangleNortheastInMeters:new Cesium.Cartesian2(20037508.34,20048966.1), customDPI: new Cesium.Cartesian2(96, 96), origin:new Cesium.Cartesian2(-20037508.34,20048966.1), scaleDenominators: [591658710.91,295829355.45,147914677.73,73957338.86,36978669.43,18489334.72,9244667.36,4622333.68,2311166.84,1155583.42, 577791.71,288895.85,144447.93,72223.96,36111.98,18055.99,9028.00,4514.00,2257.00,1128.50,564.25,282.12,141.06,70.53], // projection: new Cesium.WebMercatorProjection() }), customTags: { level: function(imageryProvider, x, y, level) { level = level; return level } } }); let imageryLayer = viewer.imageryLayers.addImageryProvider(wmtsImageryProvider); viewer.scene.camera.setView({ destination: new Cesium.Cartesian3.fromDegrees(104.94895931293581, 30.665615122103645, 1500), });
