用法总结

方法1、 HTML中直接用【script】标签包含

let bounds = {
    west: 147.13833844,
    east: 147.13856899,
    south: -41.43606916,
    north: -41.43582929
};
 
// init heatmap
let heatMap = CesiumHeatmap.create(
    myViewer, // your cesium viewer
    bounds, // bounds for heatmap layer
    {
        // heatmap.js options go here
        // maxOpacity: 0.3
    }
);
 
// random example data
let data = [{"x":147.1383442264,"y":-41.4360048372,"value":76},{"x":147.1384363011,"y":-41.4360298848,"value":63},{"x":147.138368102,"y":-41.4358360603,"value":1},{"x":147.1385627739,"y":-41.4358799123,"value":21},{"x":147.1385138501,"y":-41.4359327669,"value":28},{"x":147.1385031219,"y":-41.4359730105,"value":41},{"x":147.1384127393,"y":-41.435928255,"value":75},{"x":147.1384551136,"y":-41.4359450132,"value":3},{"x":147.1384927196,"y":-41.4359158649,"value":45},{"x":147.1384938639,"y":-41.4358498311,"value":45},{"x":147.1385183299,"y":-41.4360213794,"value":93},{"x":147.1384007925,"y":-41.4359860133,"value":46},{"x":147.1383604844,"y":-41.4358298672,"value":54},{"x":147.13851025,"y":-41.4359098303,"value":39},{"x":147.1383874733,"y":-41.4358511035,"value":34},{"x":147.1384981796,"y":-41.4359355403,"value":81},{"x":147.1384504107,"y":-41.4360332348,"value":39},{"x":147.1385582664,"y":-41.4359788335,"value":20},{"x":147.1383967364,"y":-41.4360581999,"value":35},{"x":147.1383839615,"y":-41.436016316,"value":47},{"x":147.1384082712,"y":-41.4358423338,"value":36},{"x":147.1385092651,"y":-41.4358577623,"value":69},{"x":147.138360356,"y":-41.436046789,"value":90},{"x":147.138471893,"y":-41.4359184292,"value":88},{"x":147.1385605689,"y":-41.4360271359,"value":81},{"x":147.1383585714,"y":-41.4359362476,"value":32},{"x":147.1384939114,"y":-41.4358844253,"value":67},{"x":147.138466724,"y":-41.436019121,"value":17},{"x":147.1385504355,"y":-41.4360614056,"value":49},{"x":147.1383883832,"y":-41.4358733544,"value":82},{"x":147.1385670669,"y":-41.4359650236,"value":25},{"x":147.1383416534,"y":-41.4359310876,"value":82},{"x":147.138525285,"y":-41.4359394661,"value":66},{"x":147.1385487719,"y":-41.4360137656,"value":73},{"x":147.1385496029,"y":-41.4359187277,"value":73},{"x":147.1383989222,"y":-41.4358556562,"value":61},{"x":147.1385499424,"y":-41.4359149305,"value":67},{"x":147.138404523,"y":-41.4359563326,"value":90},{"x":147.1383883675,"y":-41.4359794855,"value":78},{"x":147.1383967187,"y":-41.435891185,"value":15},{"x":147.1384610005,"y":-41.4359044797,"value":15},{"x":147.1384688489,"y":-41.4360396127,"value":91},{"x":147.1384431875,"y":-41.4360684409,"value":8},{"x":147.1385411067,"y":-41.4360645847,"value":42},{"x":147.1385237178,"y":-41.4358843181,"value":31},{"x":147.1384406464,"y":-41.4360003831,"value":51},{"x":147.1384679169,"y":-41.4359950456,"value":96},{"x":147.1384194314,"y":-41.4358419739,"value":22},{"x":147.1385049792,"y":-41.4359574813,"value":44},{"x":147.1384097378,"y":-41.4358598672,"value":82},{"x":147.1384993219,"y":-41.4360352975,"value":84},{"x":147.1383640499,"y":-41.4359839518,"value":81}];
let valueMin = 0;
let valueMax = 100;

// add data to heatmap
heatMap.setWGS84Data(valueMin, valueMax, data);

最后为了方便查看，添加场景切换

viewer.camera.flyTo({
                                destination: Cesium.Cartesian3.fromDegrees(obj.position[0], obj.position[1], 2e3),
                                orientation: {
                                    heading: Cesium.Math.toRadians(0.0),
                                    pitch: Cesium.Math.toRadians(-90.0),
                                    roll: 0.0
                                }
                            });

方法2、添加至Cesium.js文件中

1. 添加类， 代码内容 “define(‘Scene/HeatmapImageryProvider’,[”…" return
   HeatmapImageryProvider;});"整段，添加到define定义之后，Cesium定义之前，cesium里面provider有很多，HeatmapImageryProvider和他们的角色相似，CesiumTerrainProvider为例，可以查找它，然后把定义代码放在它之后
   
2. 添加 ‘./Scene/HeatmapImageryProvider’ 到Cesium另一的第一个参数， 将它加到CesiumTerrainProvider类似配置之后，
3. 添加 Scene_HeatmapImageryProvider 到Cesium第二个参数，CesiumTerrainProvider类似配置之后
   
4. 添加Cesium[‘HeatmapImageryProvider’] = Scene_HeatmapImageryProvider;，CesiumTerrainProvider类似配置之后
5. 确保已经引用了CesiumHeatmap.js
6. 使用

var instance  = new Cesium.HeatmapImageryProvider();
var layer = widget.scene.imageryLayers.addImageryProvider(instance);
