Markers

The Markers toolset is an important feature of VIZ. It allows you to annotate a 3-dimensional dataset, by placing Marker objects. Each Marker has a set of attributes, such as name, URL, or shape, so that you can use the Marker to associate data to a 3D location.

Similarly to the layers in Photoshop, every marker belongs to a Marker group. This allows you to have multiple types of markers associated to the same dataset. All Markers in the same marker group share the same color.

By saving and loading Markers, you can communicate information and datasets with other VIZ users.


Example of a flag marker


 

How to add a marker:

- Press on the Marker Button
The MarkerGroup options window appear. This example shows that there's already a Marker group called Rock_names. You can:
  • Load or Save a set of Marker groups to a file.
  • Add a new Marker group to the list.
  • Show/Hide the Marker group
  • Edit a Marker group
  • Delete a Marker group
- Press New to add a new Marker group and enter the group name and possible additional information. Then Press Ok.
- Select the new marker group you've just created in the listbox and press Edit.

This allows you to edit a Marker group. A second listbox will appear. It contains the list of Markers in your current Marker group. You can:

  • Add a Marker
  • Show/Hide individual Markers
  • Edit a Marker
  • Move a Marker

    • Delete a Marker
- Press New to create a new Marker

This is the property sheet for each Marker. In this example, we have added a Flag Marker by:

  • filling out the Marker name
  • Choosing the Marker type from the pulldown menu
  • Entering the Label, that will appear next to the flag
  • Putting additional information related to the Marker

    • Adding a URL
     
- Press Ok (or Place, if you are adding a new Marker) and point and click on the desired location in the 3D window.

Note that if you press the Move button (from the Edit Marker Group window), or Place (from the Edit Marker) window, the interface will hang and wait for you to click on a location in the 3D window.
