charts3D地球--添加航线-编程知识

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

上组件源码
