Main Page → Trackables pane
The Trackables pane can be accessed under the View tab or by clicking the icon on the main toolbar.
The Trackable pane is used for creating and editing trackable models in Motive. In common applications, rigid body models are created for tracking rigid objects, and skeleton models are created for tracking human motions. This page goes over each option in the Trackables pane.
These trackable models, also called trackable assets, store marker placement information of the target object that will be tracked. Then these models are used to automatically apply a set of predefined labels to 3D points using the labeling algorithms. Once the 3D points are labeled, Motive can process the dataset to calculate the position and orientation of the corresponding rigid bodies or skeleton segments. Then, both rigid body and skeleton tracking data can be sent to other pipelines (e.g. animations and biomechanics) for extended applications.
The trackable models can be used to auto-label 3D points both in Live mode (real-time) and in the Edit mode (post-processing). If new skeletons or rigid bodies are created during post-processing, the Take will need to be auto-labeled again in order to apply the changes to the 3D data.
Step 1. Select all associated rigid body markers in the 3D viewport.
Step 2. On the Trackables pane, confirm that the selected markers match the markers that you wish to define the rigid body from.
Step 3. Click Create, and a rigid body model will be defined from the selected markers.
Create a Rigid Body asset from the selected markers. There are three different ways:
Step 3. Once the rigid body is created, the markers will be colored (labeled) and interconnected to each other. The newly created rigid body will be listed under the Assets pane.
If the rigid bodies, or skeletons, are created in the Edit mode, the corresponding Take needs to be auto-labeled. Only then, the rigid body markers will be labeled using the rigid body asset and positions and orientations will be computed for each frame.
