用法說明
BuildingFilter
類定義了一組條件,可用於顯示或隱藏 SceneView 中 BuildingSceneLayer 的特定函數。例如,如果您想查看建築物二樓的部分,您可以設置過濾器以僅顯示二樓。通過將過濾器添加到 BuildingSceneLayer.filters 集合並將 id 分配給 BuildingSceneLayer.activeFilterId ,可以在圖層上激活過濾器。一旦過濾器被激活,隻有滿足filterBlocks定義的條件的特征才會顯示在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;
