cesium在地图上选点绘制线，绘制路径

需求：在地图上选点绘制，形成路径，最终输出经纬度/高度集合。

效果图：右键结束选点，选点之后添加路径配置信息。

代码：

<template>
  <div class="draw-path-wrap">
    <div class="path-list">
      <div
        class="path-item"
        v-for="(item, index) in pathList.data"
        :key="index"
        @click="drawPathByData(item)"
      >
        <div>{
  { item.name }}</div>
      </div>
    </div>
    <div class="create-path-btn" @click="drawPath">
      <el-icon><Plus /></el-icon>
    </div>
  </div>
  <el-dialog
    v-model="dialogVisible"
    title="路径配置"
    width="500"
    :close-on-press-escape="false"
    :close-on-click-modal="false"
    :show-close="false"
  >
    <el-form
      ref="pathFormRef"
      :model="pathForm"
      label-width="auto"
      :rules="rules"
    >
      <el-form-item label="路径名称" prop="name">
        <el-input v-model="pathForm.name" placeholder="请输入路径名称" />
      </el-form-item>
      <el-form-item label="路径高度" prop="height">
        <el-input v-model="pathForm.height" placeholder="请输入路径高度" />
      </el-form-item>
    </el-form>
    <template #footer
