cesium 图层构建的那些事 (二十三)

我们来构建视频图层

首先做定义

  • export interface PVideoEntity{
  • name?:string,
  • entity:any,
  • video:any,
  • }

视频构建图层
```javascript

import { PVideoEntity } from './PVideoEntity';
import { Tuple } from "./Tuple";

export class VideoEntity extends Tuple {
type = "VideoEntity";
public video: any;
private _url: string = "";
constructor(option: PVideoEntity) {
super();
this.setVideoDOM(option.video);
this.createEntity(option.entity);
}
set stRotation(value) {
this.cesiumObj.polygon.stRotation = Cesium.Math.toRadians(value)
}
get stRotation() {
return Cesium.Math.toDegrees(this.cesiumObj.polygon.stRotation);
}
set url(value) {
this._url = value;
this.video.src = value;
this.cesiumObj.polygon.material = this.video;
}
get url() {
return this._url;
}

  • set hierarchy(rings: any) {
  • this.cesiumObj.polygon.hierarchy = Cesium.Cartesian3.fromDegreesArray(rings.flat())
  • }
  • get hierarchy() {
  • let cartographic = Cesium.Ellipsoid.WGS84.cartesianToCartographic(this.cesiumObj.polygon.hierarchy);
  • const x = Cesium.Math.toDegrees(cartographic.longitude);
  • const y = Cesium.Math.toDegrees(cartographic.latitude);
  • const z = cartographic.height;
  • return { x, y, z };
  • }
  •  
  • public addToMap(map: any): this {
  • this.map = map;
  • map.entities.add(this.cesiumObj);
  • this.video.play();
  • return this;
  • }
  • public removeByMap(destroy: boolean = true): this {
  • if (this.cesiumObj) {
  • this.map!.entities.remove(this.cesiumObj);
  • this.video.pause();
  • if (destroy) {
  • this.video.src = "";
  • this.video.load();
  • this.video = null;
  • }
  • this.cesiumObj = null;
  • this.map = null;
  • }
  • return this;
  • }
