Value and type information for per-instance geometry attribute that determines if the geometry instance has a distance display condition.
| Name | Type | Default | Description |
|---|---|---|---|
near |
Number |
0.0
|
optional The near distance. |
far |
Number |
Number.MAX_VALUE
|
optional The far distance. |
Throws:
-
DeveloperError : far must be greater than near.
Example:
const instance = new Cesium.GeometryInstance({
geometry : new Cesium.BoxGeometry({
vertexFormat : Cesium.VertexFormat.POSITION_AND_NORMAL,
minimum : new Cesium.Cartesian3(-250000.0, -250000.0, -250000.0),
maximum : new Cesium.Cartesian3(250000.0, 250000.0, 250000.0)
}),
modelMatrix : Cesium.Matrix4.multiplyByTranslation(Cesium.Transforms.eastNorthUpToFixedFrame(
Cesium.Cartesian3.fromDegrees(-75.59777, 40.03883)), new Cesium.Cartesian3(0.0, 0.0, 1000000.0), new Cesium.Matrix4()),
id : 'box',
attributes : {
distanceDisplayCondition : new Cesium.DistanceDisplayConditionGeometryInstanceAttribute(100.0, 10000.0)
}
});See:
Members
readonly componentDatatype : ComponentDatatype
The datatype of each component in the attribute, e.g., individual elements in
DistanceDisplayConditionGeometryInstanceAttribute#value.
-
Default Value:
ComponentDatatype.FLOAT
The number of components in the attributes, i.e.,
DistanceDisplayConditionGeometryInstanceAttribute#value.
-
Default Value:
3
When
true and componentDatatype is 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:
false
The values for the attributes stored in a typed array.
-
Default Value:
[0.0, 0.0, Number.MAX_VALUE]
Methods
static Cesium.DistanceDisplayConditionGeometryInstanceAttribute.fromDistanceDisplayCondition(distanceDisplayCondition) → DistanceDisplayConditionGeometryInstanceAttribute
Creates a new
DistanceDisplayConditionGeometryInstanceAttribute instance given the provided an enabled flag and DistanceDisplayCondition.
| Name | Type | Description |
|---|---|---|
distanceDisplayCondition |
DistanceDisplayCondition | The distance display condition. |
Returns:
The new
DistanceDisplayConditionGeometryInstanceAttribute instance.
Throws:
-
DeveloperError : distanceDisplayCondition.far must be greater than distanceDisplayCondition.near
Example:
const distanceDisplayCondition = new Cesium.DistanceDisplayCondition(100.0, 10000.0);
const instance = new Cesium.GeometryInstance({
geometry : geometry,
attributes : {
distanceDisplayCondition : Cesium.DistanceDisplayConditionGeometryInstanceAttribute.fromDistanceDisplayCondition(distanceDisplayCondition)
}
});static Cesium.DistanceDisplayConditionGeometryInstanceAttribute.toValue(distanceDisplayCondition, result) → Float32Array
Converts a distance display condition to a typed array that can be used to assign a distance display condition attribute.
| Name | Type | Description |
|---|---|---|
distanceDisplayCondition |
DistanceDisplayCondition | The distance display condition value. |
result |
Float32Array | 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:
const attributes = primitive.getGeometryInstanceAttributes('an id');
attributes.distanceDisplayCondition = Cesium.DistanceDisplayConditionGeometryInstanceAttribute.toValue(distanceDisplayCondition, attributes.distanceDisplayCondition);
