    Class LineMeasurement

    LineMeasurement – Concrete measurement tool for interactively measuring 3D distances (lines) in Cesium scenes.

    Extends Measurement and uses LineDrawing for interactive drawing of a 2-point line. Automatically computes and displays the distance as a label, and updates the label as points move. Supports configuration for unit, color, and rendering state. Handles destruction and UI visibility.

    The Cesium Viewer or host application reference.

    Initial points of the measurement line.

    Color for point markers.

    Color for the line.

    Measurement unit.

    If true, will draw geometry on instantiation.

    (Optional) Parent measurement/group id.

    const meas = new LineMeasurement(viewer, {
      pointColor: Cesium.Color.RED,
      lineColor: Cesium.Color.ORANGE,
      unit: 'ft',
      render: true
    });

    console.log("Distance (m):", meas.distance);

    Accessors

    Methods

    • Finalizes and locks the measurement, displaying the final value/label. Ensures minimum two points. (Does not destroy, only finishes.)

      Returns boolean

      True if finished/locked, false if not enough points.
