成员(属性)

readonly classificationTypeProperty : Property
engine/Source/DataSources/GeometryUpdater.js 229

Gets or sets the ClassificationType Property specifying if this geometry will classify terrain, 3D Tiles, or both when on the ground.

readonly distanceDisplayConditionProperty : Property
engine/Source/DataSources/GeometryUpdater.js 217

Gets or sets the DistanceDisplayCondition Property specifying at what distance from the camera that this geometry will be displayed.

readonly entity : Entity
engine/Source/DataSources/GeometryUpdater.js 97

Gets the entity associated with this geometry.

readonly fillEnabled : boolean
engine/Source/DataSources/GeometryUpdater.js 109

Gets a value indicating if the geometry has a fill component.

readonly fillMaterialProperty : MaterialProperty
engine/Source/DataSources/GeometryUpdater.js 138

Gets the material property used to fill the geometry.

readonly geometryChanged : boolean
engine/Source/DataSources/GeometryUpdater.js 280

Gets an event that is raised whenever the public properties of this updater change.

readonly hasConstantFill : boolean
engine/Source/DataSources/GeometryUpdater.js 121

Gets a value indicating if fill visibility varies with simulation time.

readonly hasConstantOutline : boolean
engine/Source/DataSources/GeometryUpdater.js 162

Gets a value indicating if the geometry has an outline component.

readonly id : string
engine/Source/DataSources/GeometryUpdater.js 85

Gets the unique ID associated with this updater

readonly isClosed : boolean
engine/Source/DataSources/GeometryUpdater.js 255

Gets a value indicating if the geometry is closed. This property is only valid for static geometry.

readonly isDynamic : boolean
engine/Source/DataSources/GeometryUpdater.js 242

Gets a value indicating if the geometry is time-varying.

readonly outlineColorProperty : Property
engine/Source/DataSources/GeometryUpdater.js 179

Gets the Color property for the geometry outline.

readonly outlineEnabled : boolean

Gets a value indicating if the geometry has an outline component.

readonly outlineWidth : number
engine/Source/DataSources/GeometryUpdater.js 192

Gets the constant with of the geometry outline, in pixels. This value is only valid if isDynamic is false.

readonly shadowsProperty : Property
engine/Source/DataSources/GeometryUpdater.js 205

Gets the property specifying whether the geometry casts or receives shadows from light sources.

方法

createFillGeometryInstance(time) → GeometryInstance
engine/Source/DataSources/GeometryUpdater.js 328

Creates the geometry instance which represents the fill of the geometry.
参数名称 类型 描述信息
time JulianDate The time to use when retrieving initial attribute values.
返回值:
The geometry instance representing the filled portion of the geometry.
Throws:
  • DeveloperError : This instance does not represent a filled geometry.

createOutlineGeometryInstance(time) → GeometryInstance
engine/Source/DataSources/GeometryUpdater.js 340

Creates the geometry instance which represents the outline of the geometry.
参数名称 类型 描述信息
time JulianDate The time to use when retrieving initial attribute values.
返回值:
The geometry instance representing the outline portion of the geometry.
Throws:
  • DeveloperError : This instance does not represent an outlined geometry.

destroy()
engine/Source/DataSources/GeometryUpdater.js 357

Destroys and resources used by the object. Once an object is destroyed, it should not be used.
Throws:
  • DeveloperError : This object was destroyed, i.e., destroy() was called.

isDestroyed() → boolean
engine/Source/DataSources/GeometryUpdater.js 348

Returns true if this object was destroyed; otherwise, false.
返回值:
True if this object was destroyed; otherwise, false.

isFilled(time) → boolean
engine/Source/DataSources/GeometryUpdater.js 309

Checks if the geometry is filled at the provided time.
参数名称 类型 描述信息
time JulianDate The time for which to retrieve visibility.
返回值:
true if geometry is filled at the provided time, false otherwise.

isOutlineVisible(time) → boolean
engine/Source/DataSources/GeometryUpdater.js 293

Checks if the geometry is outlined at the provided time.
参数名称 类型 描述信息
time JulianDate The time for which to retrieve visibility.
返回值:
true if geometry is outlined at the provided time, false otherwise.
