### 使用 ###

// 自定义纹理材质
          let MaterialLineImage = [
            './src/line.png',
            './src/line2.png',
            './src/line3.png',
          ]
    
          // color
          let colors = [
            new Cesium.Color(77 / 255, 201 / 255, 255 / 255, 1),
            new Cesium.Color(255 / 255, 201 / 255, 38 / 255, 1),
            new Cesium.Color(221 / 255, 221 / 255, 221 / 255, 1)
          ];
    
          // 创建材质线
          let getCustomMaterialLine = (image, color) => {
            return new Cesium.CustomMaterialLine({
              image: image,
              color: color,
              duration: 2000
            })
          }
          // 添加实体线
          let startPoint = Cesium.Cartesian3.fromDegrees(104.081701757991, 30.627042558105988)
          let glowingLine = null
          for (let i = 0, len = 8; i < len; i++) {
    
            let endPoint = Cesium.Cartesian3.fromDegrees((Math.random() / 100) +
              104.081701757991, (Math.random() / 100) + 30.627042558105988);
            glowingLine = viewer.entities.add({
              polyline: {
                positions: [startPoint, endPoint],
                width: 5,
                material: getCustomMaterialLine(MaterialLineImage[i % 3], colors[i % 3]),
              }
            });
          }
