KBE3D / KBCore / Cesium / DistanceDisplayConditionGeometryInstanceAttribute

类: DistanceDisplayConditionGeometryInstanceAttribute

Value and type information for per-instance geometry attribute that determines if the geometry instance has a distance display condition.

示例

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)
  }
});

参数

The near distance.

参数

The far distance.

属性

value

value: Float32Array

The values for the attributes stored in a typed array.

---

componentDatatype

readonly componentDatatype: ComponentDatatype

The datatype of each component in the attribute, e.g., individual elements in DistanceDisplayConditionGeometryInstanceAttribute#value.

---

componentsPerAttribute

readonly componentsPerAttribute: number

The number of components in the attributes, i.e., DistanceDisplayConditionGeometryInstanceAttribute#value.

---

normalize

readonly normalize: boolean

When <code>true</code> and <code>componentDatatype</code> 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.

方法

fromDistanceDisplayCondition()

static fromDistanceDisplayCondition(distanceDisplayCondition: DistanceDisplayCondition): DistanceDisplayConditionGeometryInstanceAttribute

Creates a new DistanceDisplayConditionGeometryInstanceAttribute instance given the provided an enabled flag and DistanceDisplayCondition.

参数

distanceDisplayCondition

DistanceDisplayCondition

The distance display condition.

返回

DistanceDisplayConditionGeometryInstanceAttribute

The new DistanceDisplayConditionGeometryInstanceAttribute instance.

示例

const distanceDisplayCondition = new Cesium.DistanceDisplayCondition(100.0, 10000.0);
const instance = new Cesium.GeometryInstance({
  geometry : geometry,
  attributes : {
    distanceDisplayCondition : Cesium.DistanceDisplayConditionGeometryInstanceAttribute.fromDistanceDisplayCondition(distanceDisplayCondition)
  }
});

---

toValue()

static toValue(distanceDisplayCondition: DistanceDisplayCondition, result?: Float32Array<ArrayBufferLike>): Float32Array

Converts a distance display condition to a typed array that can be used to assign a distance display condition attribute.

参数

distanceDisplayCondition

DistanceDisplayCondition

The distance display condition value.

result?

Float32Array<ArrayBufferLike>

The array to store the result in, if undefined a new instance will be created.

返回

Float32Array

The modified result parameter or a new instance if result was undefined.

示例

const attributes = primitive.getGeometryInstanceAttributes('an id');
attributes.distanceDisplayCondition = Cesium.DistanceDisplayConditionGeometryInstanceAttribute.toValue(distanceDisplayCondition, attributes.distanceDisplayCondition);

构造函数
