How does Wikitude 3D tracking work?The Wikitude SDK tracks 3D scenes by identifying feature points of objects and environments. By identifying feature-rich environments, the SDK will map the scene by displaying a point cloud over the different feature points. As an example on how the Wikitude 3D tracking works in a small scene, we will use the scenario of an office table. The richer the scene is equipped with feature points, the better the mapping and tracking will be. In order to track and map the scene the following steps should be taken:
- Launch the Wikitude sample app, which is included in the Native SDK (iOS and Android) download package
- Record a tracking map by slowly moving the device from one side to the other of the scene, covering the whole area
- 3D point clouds will appear on the screen capturing key feature points of the scenario
- Save the tracking map
- Load the map in your augmented reality experience to relocalize the scene and visualize the augmentation in real time.
