用法说明

PointSymbol3D 用于在 3D SceneView 中渲染具有 Point 几何的特征。 2D MapViews 不支持此符号类型。

PointSymbol3D 必须至少包含一个符号层才能在视图中渲染。必须使用以下一种或多种symbol layer 类型来定义 3D 点符号：

Symbol3DLayer 类型	扁平/体积	尺寸单位
IconSymbol3DLayer	flat	points
ObjectSymbol3DLayer	volumetric	meters
TextSymbol3DLayer	flat	points

请参阅Symbol3DLayer 和Symbol3D 以阅读有关 3D 符号、符号层以及它们如何相互关联的更多一般信息。

例子：

let symbol = {
  type: "point-3d",  // autocasts as new PointSymbol3D()
  symbolLayers: [{
    type: "object",  // autocasts as new ObjectSymbol3DLayer()
    width: 5,    // diameter of the object from east to west in meters
    height: 10,  // height of object in meters
    depth: 15,   // diameter of the object from north to south in meters
    resource: { primitive: "cube" },
    material: { color: "red" }
  }]
};
