new ShowGeometryInstanceAttribute(show)
Value and type information for per-instance geometry attribute that determines if the geometry instance will be shown.
| Name | Type | Default | Description |
|---|---|---|---|
show |
Boolean |
true
|
optional Determines if the geometry instance will be shown. |
Example:
var instance = new Cesium.GeometryInstance({
geometry : new Cesium.BoxGeometry({
vertexFormat : Cesium.VertexFormat.POSITION_AND_NORMAL,
dimensions : new Cesium.Cartesian3(1000000.0, 1000000.0, 500000.0)
}),
modelMatrix : Cesium.Matrix4.multiplyByTranslation(Cesium.Transforms.eastNorthUpToFixedFrame(
Cesium.Cartesian3.fromDegrees(-75.59777, 40.03883), new Cesium.Cartesian3(0.0, 0.0, 1000000.0)),
id : 'box',
attributes : {
show : new Cesium.ShowGeometryInstanceAttribute(false)
}

Members
-
readonlycomponentDatatype :ComponentDatatype
-
The datatype of each component in the attribute, e.g., individual elements in
ColorGeometryInstanceAttribute#value.-
Default Value:
ComponentDatatype.UNSIGNED_BYTE -
readonlycomponentsPerAttribute :Number
-
The number of components in the attributes, i.e.,
ColorGeometryInstanceAttribute#value.-
Default Value:
1 -
readonlynormalize :Boolean
-
When
trueandcomponentDatatypeis an integer format, indicate that the components should be mapped to the range [0, 1] (unsigned) or [-1, 1] (signed) when they are accessed as floating-point for rendering.-
Default Value:
true -
value :Uint8Array
-
The values for the attributes stored in a typed array.
-
Default Value:
[1.0]
Methods
-
staticShowGeometryInstanceAttribute.toValue(show, result) → Uint8Array
-
Converts a boolean show to a typed array that can be used to assign a show attribute.
Name Type Description showBoolean The show value. resultUint8Array optional The array to store the result in, if undefined a new instance will be created. Returns:
The modified result parameter or a new instance if result was undefined.Example:
var attributes = primitive.getGeometryInstanceAttributes('an id'); attributes.show = Cesium.ShowGeometryInstanceAttribute.toValue(true, attributes.show);
