This article mainly introduces how to achieve the thermal map in Cesium, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

In the Cesium base, you can display the heat map, and there is open source code on the Internet. The specific reference URL is as follows:

Https://github.com/danwild/CesiumHeatmap

The mode of use is as follows:

Function testLoc () {

/ / set the four to four ranges of the thermal map

Let bounds = {

West: 116.13833844

East: 116.13956899

South: 37.43582929

North: 37.43706916

}

/ / I initialize the thermal map

Let heatMap = CesiumHeatmap.create (

Viewer, / / your cesium viewer

Bounds, / / bounds for heatmap layer

{

/ / heatmap.js options go here

MaxOpacity: 0.75

}

);

/ / set some random effects, which can be developed according to the actual data
