Displaying Scene Measurements

The real world measurements of a scene can be displayed using the following code.

The dimensions will be calculated automatically but are likely to have some error in them due to the difference between virtual and real worlds, so optionally the dimensions can be added as a string to display.

comms.send('displayMeasurements', {
  display: <true|false>,
  width: <?string>,
  height: <?string>,
  depth: <?string>
