DEJA_ Vu3d - 052 of cesium feature set - Simulation of satellite orbit (high altitude) effect

Preface  

The main purpose of writing this column is to understand the work based on Cesium Integrate the realized functions , Have their own thinking and realization , There are also references to other great God finishing implementation , After preliminary calculation, there are almost small 130 About functions , The follow-up will also continue to add , So I'm going to spend a week 2-3 Update this column with a better look （ Keep the code as concise as possible ）. If there are errors or improvements in the content of the blog , I also hope to communicate with you here to improve .

Introduce

The content of the column should be as concise as possible , In this article, we will introduce the system based on Cesium Simulation of satellite orbit （ High altitude scanning ） effect . The effect is shown in the figure

The implementation of function effect is very simple , I don't say much nonsense , Go straight to the code ：

Key code

Track creation

function computeCirclularFlight(source, type) {
  let property = new Cesium.SampledPositionProperty();
  if (type == 1) {
    // Satellite position 
    for (let i = 0; i < source.values.length; i++) {
      let time = Cesium
