Class: MeasurementTool

@cognite/reveal/tools.MeasurementTool

Enables {@see Cognite3DViewer} to perform a point to point measurement. This can be achieved by selecting a point on the 3D Object and drag the pointer to required point to get measurement of the distance. The tools default measurement is in "Meters" as supported in Reveal, but it also provides user to customise the measuring units based on their convinience with the callback.

example

const measurementTool = new MeasurementTool(viewer);
measurementTool.enterMeasurementMode();
// ...
measurementTool.exitMeasurementMode();

// detach the tool from the viewer
measurementTool.dispose();
