雷达扫描效果,canvas 生成扇形扫描贴图并按帧旋转。

简介

MapboxRadar 在点要素上渲染雷达扫描:canvas 生成扇形扫描贴图,symbol 图层按帧旋转;color / radius / speed 控制颜色、扫描半径与转速。

用法

调整 speed(度/秒)观察扫描转速:

<script setup lang="ts">
import type { FeatureCollection } from 'geojson'

withDefaults(defineProps<{ speed?: number }>(), {
  speed: 120
})

const data: FeatureCollection = {
  type: 'FeatureCollection',
  features: [
    {
      type: 'Feature',
      properties: {},
      geometry: { type: 'Point', coordinates: [116.397, 39.908] }
    },
    { type: 'Feature', properties: {}, geometry: { type: 'Point', coordinates: [116.46, 39.92] } }
  ]
}
</script>

<template>
  <div class="h-115 w-full overflow-hidden rounded-(--ui-radius) border border-default">
    <MapboxMap
      :options="{ style: 'mapbox://styles/mapbox/dark-v11', center: [116.43, 39.913], zoom: 11 }"
    >
      <MapboxRadar :data="data" :speed="speed" color="#22c55e" />
    </MapboxMap>
  </div>
</template>
