Creating 3D Tracking Maps
To be able to use 3D Tracking in your Wikitude powered application, you will need to create a so called Tracking Map. This Tracking Map is a simple file (.wtm file) which contains all the information needed by the Wikitude SDK to track the 3D objects of your choice. Similar to a .wtc file you might know from 2D tracking you later have the choice of packaging the Tracking Map file within your app or store it on a web server and let the Wikitude SDK download it.
Quality of the Tracking Map
The Map recorder and the 3D Tracking sample in the sample app both include a high-level quality indicator, when you record a map. This quality indicator gives you a first estimate how well the tracking performance will be. There are tree levels, which will be displayed
- Bad: There are too few points available to recognize and track the object
- Average: There are few points available to recognize and track the object. This will result in increased shaking and varying recognition results.
- Good: The algorithm has found enough points to recognize and track the object
Check out the guide 3D Tracking Guidelines and best practices how to come to a decent recognition and tracking result.
Editing a recorded Tracking Map
During the beta phase of 3D tracking it is not possible to edit the tracking map after it has been saved.
