GeometryUpdater

new Cesium.GeometryUpdater(entity, scene)
DataSources/GeometryUpdater.js 30

Defines the interface for a geometry updater. A GeometryUpdater maps geometry defined as part of a Entity into Geometry instances. These instances are then visualized by GeometryVisualizer. This type defines an interface and cannot be instantiated directly.
Name Type Description
entity Entity The entity containing the geometry to be visualized.
scene Scene The scene where visualization is taking place.

Members

staticCesium.GeometryUpdater.materialAppearanceType : Appearance
DataSources/GeometryUpdater.js 48

Gets the type of Appearance to use for material-based geometry.

staticCesium.GeometryUpdater.perInstanceColorAppearanceType : Appearance
DataSources/GeometryUpdater.js 40

Gets the type of Appearance to use for simple color-based geometry.

readonlyentity : Entity
DataSources/GeometryUpdater.js 61

Gets the entity associated with this geometry.

readonlyfillEnabled : Boolean
DataSources/GeometryUpdater.js 71

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

readonlyfillMaterialProperty : MaterialProperty
DataSources/GeometryUpdater.js 91

Gets the material property used to fill the geometry.

readonlygeometryChanged : Boolean
DataSources/GeometryUpdater.js 166

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

readonlyhasConstantFill : Boolean
DataSources/GeometryUpdater.js 81

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

readonlyhasConstantOutline : Boolean
DataSources/GeometryUpdater.js 111

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

readonlyisClosed : Boolean
DataSources/GeometryUpdater.js 155

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

readonlyisDynamic : Boolean
DataSources/GeometryUpdater.js 144

Gets a value indicating if the geometry is time-varying. If true, all visualization is delegated to the DynamicGeometryUpdater returned by GeometryUpdater#createDynamicUpdater.

readonlyoutlineColorProperty : Property
DataSources/GeometryUpdater.js 121

Gets the Color property for the geometry outline.

readonlyoutlineEnabled : Boolean
DataSources/GeometryUpdater.js 101

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

readonlyoutlineWidth : Number
DataSources/GeometryUpdater.js 132

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

Methods

createDynamicUpdater(primitives) → DynamicGeometryUpdater
DataSources/GeometryUpdater.js 236

Creates the dynamic updater to be used when GeometryUpdater#isDynamic is true.
Name Type Description
primitives PrimitiveCollection The primitive collection to use.
Returns:
The dynamic updater used to update the geometry each frame.
Throws:

createFillGeometryInstance(time) → GeometryInstance
DataSources/GeometryUpdater.js 198

Creates the geometry instance which represents the fill of the geometry.
Name Type Description
time JulianDate The time to use when retrieving initial attribute values.
Returns:
The geometry instance representing the filled portion of the geometry.
Throws:
  • DeveloperError : This instance does not represent a filled geometry.

createOutlineGeometryInstance(time) → GeometryInstance
DataSources/GeometryUpdater.js 209

Creates the geometry instance which represents the outline of the geometry.
Name Type Description
time JulianDate The time to use when retrieving initial attribute values.
Returns:
The geometry instance representing the outline portion of the geometry.
Throws:
  • DeveloperError : This instance does not represent an outlined geometry.

destroy()
DataSources/GeometryUpdater.js 225

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
DataSources/GeometryUpdater.js 217

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

isFilled(time) → Boolean
DataSources/GeometryUpdater.js 187

Checks if the geometry is filled at the provided time.
Name Type Description
time JulianDate The time for which to retrieve visibility.
Returns:
true if geometry is filled at the provided time, false otherwise.

isOutlineVisible(time) → Boolean
DataSources/GeometryUpdater.js 178

Checks if the geometry is outlined at the provided time.
Name Type Description
time JulianDate The time for which to retrieve visibility.
Returns:
true if geometry is outlined at the provided time, false otherwise.
