cesium-wind's Introduction

cesium-wind

implement dynamic wind in Cesium

示例

格网风场

数据源

你从index.js中可以看到我使用的是uvwind_d01.json数据。 数据可以按照你的方式进行组织,只要方便读取,我只解释下这个数据的格式。

风场数据由风速X分量和Y分量组成,每个分量格式都是一致的:

  • data (Array) 当前分量每个格点的风速大小(m/s)。

  • header (Object) 描述风场信息是如何组织的

  • meta (Object) 描述风场的一些基本信息,如日期等。

方法

总结

目前在Cesium中实现动态风场,使用Cesium.PolylineGeometry几何元素进行模拟,效果仍然不满意,应该有更好的方法。
