Type Alias IAnalysis

地形分析模块

在有地形的情况下，根据点生成线；根据经纬度获取地形坐标点；获取多个经纬度点的总距离

type IAnalysis = {
    distanceOfPoints: (points: [Vector3, Vector3, ...Vector3[]]) => number;
    pickTerrainLine: (
        start: Vector2,
        end: Vector2,
        tolerance?: number,
        classificationType?: ClassificationType,
    ) => Promise<Vector3[]>;
    pickTerrainPoint: (point: Vector2) => Promise<Vector3 | undefined>;
}

Properties

distanceOfPoints

distanceOfPoints: (points: [Vector3, Vector3, ...Vector3[]]) => number

获取指定经纬度点间距离

Type declaration

- (points: [Vector3, Vector3, ...Vector3[]]): number
- Parameters
  - points: [Vector3, Vector3, ...Vector3[]]
    带地形高度的经纬度坐标
  Returns number
  总距离

pickTerrainLine

pickTerrainLine: (
    start: Vector2,
    end: Vector2,
    tolerance?: number,
    classificationType?: ClassificationType,
) => Promise<Vector3[]>

根据起点终点生成一条贴地形的线

Type declaration

- (
      start: Vector2,
      end: Vector2,
      tolerance?: number,
      classificationType?: ClassificationType,
  ): Promise<Vector3[]>
- Parameters
  - start: Vector2
    起点经纬度坐标
  - end: Vector2
    终点经纬度坐标
  - Optionaltolerance: number
    精度容限，单位米。默认1米。容限越低，生成的线的精度越高，但相应的生成时间会越长
  - OptionalclassificationType: ClassificationType
    拾取地形或模型表面的分类方式
  Returns Promise<Vector3[]>
  线的点串。当没有地形或地形获取失败时，可能为空数组

pickTerrainPoint

pickTerrainPoint: (point: Vector2) => Promise<Vector3 | undefined>

获取指定经纬度点在地形上的点坐标

Type declaration

- (point: Vector2): Promise<Vector3 | undefined>
- Parameters
  - point: Vector2
    经纬度坐标
  Returns Promise<Vector3 | undefined>
  带地形高度的经纬度坐标。获取失败时返回 undefined
