CesiumInspectorViewModel

简介

CesiumInspectorViewModel 是 CesiumJS 库中的一个模块,是 Cesium Inspector(调试器)的视图模块。它提供了与调试器相关的一些状态和操作,可以方便地开启和关闭调试器,调整场景的光照、背景等设置,查看和更改场景中的属性和状态,帮助用户进行场景的调试和优化。

属性

enabled:Boolean

表示调试器是否启用。如果启用,则调试器视图将显示在 scene 的右侧。

isDestroyed:Boolean

指示模型是否已被销毁。

scene:Scene

表示将使用该调试器的场景。

camera:Camera

表示当前视角的相机。

frustumStatistic:Object

包含一些与场景剔除相关的统计数据,例如被剔除的 primitive 的数目等。

debugFrustum: DebugCameraPrimitive

一个用于显示当前相机视锥体的 primitive。

performanceContainer: HTMLElement

调试器的容器元素。

showStatistics:Boolean

表示是否显示场景相关的统计信息。

showCamera:Boolean

表示是否显示当前相机的状态和属性信息。

showShadowVolumes:Boolean

表示是否显示场景中的阴影体积(Shadow Volumes)。

baseLayerPicker:BaseLayerPickerViewModel

表示当前场景使用的底图选择器。

selectionIndicator:SelectionIndicatorViewModel

表示当前场景的选择指示器(SelectionIndicator)。

infoBox:InfoBoxViewModel

表示当前场景的信息框(InfoBox)。

homeButton:HomeButtonViewModel

表示当前场景的返回 Home 按钮。

sceneModePicker:SceneModePickerViewModel

表示当前场景的场景模式选择器。

projectionPicker:ProjectionPickerViewModel

表示当前场景的投影方式选择器。

navigationBar:NavigationViewModel

表示当前场景的导航工具栏。

timeline:TimelineViewModel

表示当前场景的时间轴。

animation:AnimationViewModel

表示当前场景的动画控制面板。

fullscreenButton:FullscreenButtonViewModel

表示全屏按钮(双击画布也可以进入全屏)。

geocoder:GeocoderViewModel

表示地理编码器,用于在场景中搜索地点。

sceneMode:String

当前场景的场景模式,可以是 "3D"、"2D" 或 "COLUMBUS_VIEW" 中的一个。

lightSettings:LightSettingsViewModel

表示场景的光照设置视图模型。

imagerySettings:ImagerySettingsViewModel

表示场景的图像设置视图模型。

terrainSettings:TerrainSettingsViewModel

表示场景的地形设置视图模型。

imagerySplitPosition:Number

表示当前场景的图像切分比例。

方法

destroy():void

销毁该实例及其资源。

isDestroyed():Boolean

判断实例是否已被销毁。

toggleEnabled():void

开启/关闭调试器。

`enablePerformance():void

启用场景统计信息的显示。

`disablePerformance():void

禁用场景统计信息的显示。

事件

performanceChanged

场景统计信息的显示状态发生变化时触发。

toggleEvent

调试器的开启/关闭状态发生变化时触发。

示例

const viewer = new Cesium.Viewer('cesiumContainer');
const inspector = viewer.scene.debugShowFramesPerSecond(true);
const stats = viewer.scene.debugShowStatistics(true);
const debug = viewer.scene.debugShowShadowVolumes(true);

console.log(inspector.enabled);  // true
console.log(stats.enabled);  // true
console.log(debug.enabled);  // true

// 禁用调试器和统计信息的显示
inspector.enabled = false;
stats.enabled = false;
