nuxt.js引入echarts旋转地球

要在Nuxt.js中引入echarts旋转地球，需要执行以下步骤：

1. 安装echarts和echarts-gl

通过npm或yarn安装echarts和echarts-gl：

npm install echarts echarts-gl

或者

yarn add echarts echarts-gl

2. 创建组件

在components文件夹中创建一个新的组件，例如Earth.vue，并在其中添加以下代码：

<template>
  <div ref="chart" style="height: 500px;"></div>
</template>

<script>
import echarts from 'echarts'
import 'echarts-gl'

export default {
  mounted () {
    this.chart = echarts.init(this.$refs.chart)
    this.chart.setOption({
      globe: {
        baseTexture: '/earth.jpg',
        heightTexture: '/bathymetry_bw_composite_4k.jpg',
        displacementScale: 0.075,
        shading: 'realistic',
        environment: '/starfield.jpg',
        realisticMaterial: {
          roughness: 0.2,
          metalness: 0,
          textureTiling: [8, 4]
        },
        postEffect: {
          enable: true,
          SSAO: {
            enable: true,
            radius: 2,
            intensity: 1.5,
            quality: 'high'
          }
        },
        light: {
          main: {
            intensity: 5,
            shadow: true
          },
          ambient: {
            intensity: 0
          },
          ambientCubemap: {
            texture: '/lightmap.hdr',
            exposure: 1,
            diffuseIntensity: 0.5,
            specularIntensity: 2
          }
        }
      },
      series: [
        {
          type: 'lines3D',
          coordinateSystem: 'globe',
          data: [
            [
              {
                coord: [113.8953, 22.901],
                value: 100
              },
              {
                coord: [2.3412, 48.8566]
              }
            ],
            [
              {
                coord: [113.8953, 22.901],
                value: 100
              },
              {
                coord: [-74.0059, 40.7128]
              }
            ],
            [
              {
                coord: [113.8953, 22.901],
                value: 100
              },
              {
                coord: [139.6917, 35.6895]
              }
            ]
          ],
          lineStyle: {
            width: 1,
            color: '#00ffff'
          }
        }
      ]
    })
    this.chart.setOption({
      globe: {
        viewControl: {
          autoRotate: true,
          autoRotateAfterStill: 10,
          distance: 200
        }
      }
    })
  },
  beforeDestroy () {
    if (this.chart) {
      this.chart.dispose()
      this.chart = null
    }
  }
}
</script>

<style>
@import url('https://cdn.jsdelivr.net/npm/echarts-gl/dist/echarts-gl.min.css');

body {
  margin: 0;
}

* {
  box-sizing: border-box;
}
</style>

3. 测试

在页面中使用新创建的组件：

<template>
  <div>
    <Earth />
  </div>
</template>

<script>
import Earth from '@/components/Earth.vue'

export default {
  components: {
    Earth
  }
}
</script>

保存并运行应用程序，地球应该开始旋转。
