cesiumheatmap's Introduction

CesiumHeatmap

修改了CesiumHeatmap的源码,提供修改bounds和缩放修改热力图效果

Demo

修改半径

修改区域

修改半径

通过事件修改传入数据半径,重新设置数据

// 镜头移动事件
var camera = viewer.camera
    viewer.scene.camera.moveEnd.addEventListener(function(){
        var height = camera.positionCartographic.height
        sourceData.forEach(function(v) {
          v.radius = height/20000
        })
        heatMap.setWGS84Data(0, 100, sourceData)
    })

修改区域

heatMap实例调用changeBounds方法即可

    heatMap.changeBounds(bounds)
    heatMap.setWGS84Data(0, 100, sourceData)
