Using AR markers and 3D objects

Updated 2 years ago by Corine Barbazanges

1. CREATE AR MARKERS

AR markers can be positioned wherever you choose and tied to the contents that you wish your visitors to see in augmented reality through their Tango application.

  1. Open GuidiGO Studio and head to the 2bis-AR tab of your tour.
  2. Find the desired stop and click the Add Object/Marker button.
  3. Choose Marker in the Type drop-down menu, then choose the one you want.


  4. Assign a name to your marker that will allow you to identify it easily in AR composer when you’re positioning it in augmented reality.
  5. Add your content (text or file)
  6. To format a text marker, type it inside the square brackets [b] to make your text bold [/b] or [i] to italicize your text [/i].
  7. If you wish, you can display your instructions to the user. They will appear in a pop-up, along with the markers. In order to do this, click the Add instructions for the markers button located under the name of the stop. The text you enter into the Title field will allow the visitor to identify the markers in the stop’s menu, while it offers multiple AR experiences.


2. CREATE 3D OBJECTS 

Your tour’s 3D objects will appear in augmented reality inside the AR Player application.

They first need to be converted to Unity bundles (visit this page to see how to proceed - work in progress). Then, follow these steps:

  1. Open GuidiGO Studio and head to the 2bis-AR tab of your tour.
  2. Find the desired stop and click the Add Object/Marker button.
  3. Choose 3D Object in the Type drop-down menu on the left.
  4. Click the Add an object button and load your Unity bundle.
  5. If you wish, you can display your instructions to the user. They will appear in a pop-up, along with the object.
  6. The name you assign to the object has two functions:
    1. allow you to identify it easily in AR composer when you’re positioning it in augmented reality. 
    2. allow the visitor to identify the object in the stop’s menu, while it offers multiple AR experiences.


3. PLACE MARKERS AND OBJECTS IN THE REAL WORLD

Launch the AR Composer application on your Tango device and select your tour in the list. Make sure to have a working internet connection.

Before you can position the markers or the objects, you need to match your 2D floor plan with the 3D space (ADF) of your galleries. You can find the details of this process here.
  1. Tap the cube-shaped icon located in the corner of the map.
  2.  Position each marker/object by following the steps described here.


4. UPDATE YOUR TOUR

Go back to GuidiGO Studio

  1. Select your tour, then head to the 5.Publish tab. 
  2. Click the Publish update button.

After you’ve published your updated tour, take the following steps: 

  1. Launch your visitors' Tango application.
  2. Tap Update on the tour cover.
Before you launch AR Player, make sure that you have quit AR Composer, as simultaneous use of these two applications can generate conflicts.



REPLACE A MARKER OR AN OBJECT

  1. Head to the 2.bis AR tab.
  2. Click the marker/object to be modified, then click the orange Change... [object/image/audio/video] link.
  3. Load the new file and click Save.
  4. Publish the tour update so your changes will be visible in your visitors’ application.
By performing this action, you will retain the position and the rotation you applied inside AR Composer, and therefore avoid having to position the marker or object again.
