charts3D地球--添加航线

要在地球视角下画出海运路线图

方案

添加 globl 地球
创建geo地理坐标系
创建canvas对象用于承载地图世界地图this.worldChart

//初始化canvas节点
      let cav = document.createElement("canvas");
      this.$echarts.registerMap("world", geoJson);
      this.worldChart = this.$echarts.init(cav, null, {
        width: 4096,
        height: 2048,
      });
      this.worldChart.setOption(this.worldChartOption);

设置globl 的baseTexture为this.worldChart
添加lines3D飞线效果
