Annotations

In VRGS, annotations are non-geological elements such as scale bars, waypoints, and measurements.

Measurements

The Measure Vertical option permits a user to measure features and distances on a 3D model. The measurement is saved in the Intepretations project tree. This option is a split button with the following extended options:

No.	Measurement	Description
1.	Vertical	The default option (same as the top half of the button). Select 2 points on the model to get the vertical distance between the 2 points.
2.	Horizontal	Select 2 points on the model to get the horizontal or map distance between the 2 points.
3.	Measure 3D	Select 2 points on the model to get the straight line distance between the 2 points. The orientation of the line is calculated. A difference between x,y,z positions is calculated to provide a Corrected distance measurement.
4.	Measure Multi 3D	You can selected multiple points on the outcrop. A measurement will be taken between every point such that multiple distances will be calculated. The difference with the to get the difference betweenSelect 2 points on the model to get the straight line distance between the 2 points. between x,y,z positions is calculated to provide a Corrected distance measurement, for all measurements.

Other annotations

No.	Measurement	Description
1.	Scale Bar	Select a point in the model to add a virtual scale bar at that point. The default scale bar is 5.0 m high with 5 segments that are each 1 m. The scale bar dimensions, colour, and size can be modified by editing its properties in the Properties Panel.
2.	Tape Measure	This tool allows a quick bespoke measurement between two points. The distgance between the points are updated and displayed in real-time. Unlike the other Measurements (Vertcial, Horizontal, Measure 3D, Measure Multi 3D), this measurement is not stored in the project.
3.	Waypoint	This is a simple marker. Click the model where you want to add a waypoint. Waypoints can also be imported into the model from waypoints group in the data tab.
3.	GCP	You have the ability to Add Tiepoint and Add Tiepoint and Target to the 3D model. This can be used to georeference a model if grouned control data is acquired.
4.	Sample	Add a point at the location where field samples were collected.
5.	Multimedia	This allows you to link other kinds of media into your model such as photographs, videos, or presentations amongst others. The media will be launched into the appropriate external application. Click the location on the model that you wish to add a media item, then add the link to the relevant file in the options tab.
6.	Label	You can choose point or location on the 3D model and add a text label.
7.	Web Link	Similar to the Label and Multimedia, you can choose a point or location on the 3D model. You can add a multimedia file to the 3D outcrop.
8.	Orthopanel	This tool allows you to create a 2D orthopanel view of the 3D model. You can choose to create an orthopanel from 2 Points or 3 Points. The 3 Points options allows you to create an orthopanel at an arbitrary position and angle/view.
