基本信息
以下是所在类或对象的基本信息。
AMD:
require(["esri/layers/support/BuildingFilter"], (BuildingFilter) => { /* code goes here */ });
ESM:
import BuildingFilter from "@arcgis/core/layers/support/BuildingFilter";
类:
esri/layers/support/BuildingFilter
继承: BuildingFilter > Accessor
自从:用于 JavaScript 4.12 的 ArcGIS API
用法说明
BuildingFilter
类定义了一组条件,可用于显示或隐藏 SceneView 中 BuildingSceneLayer 的特定函数。例如,如果您想查看建筑物二楼的部分,您可以设置过滤器以仅显示二楼。通过将过滤器添加到 BuildingSceneLayer.filters 集合并将 id 分配给 BuildingSceneLayer.activeFilterId ,可以在图层上激活过滤器。一旦过滤器被激活,只有满足filterBlocks定义的条件的特征才会显示在SceneView中。
例子:
// define a floor filter
const buildingFilter = new BuildingFilter({
filterBlocks: [{
// an SQL expression that filters using the BldgLevel field
filterExpression: "BldgLevel = 3",
filterMode: {
type: "wire-frame",
edges: {
type: "solid",
color: [0, 0, 0, 0.8]
}
}
}]
});
// set the filter in the filters array on the layer
buildingLayer.filters = [buildingFilter];
// specify which filter is the one that should be applied
buildingLayer.activeFilterId = buildingFilter.id;
