Once Motive is prepared, the next step is to place markers on the subject and create corresponding assets in Motive. There are three different types of assets in Motive:
- Rigid Body
For each Take, included assets are displayed in the Project Pane, and related properties show up at the bottom when an asset is selected. Assets may be created during Live (before capture) or Post(after capture, from a loaded TAK).
The MarkerSet is simply a list of marker labels that are used to annotate reconstructed markers. MarkerSets should only be used in situations where it is not possible to define a Rigid Body or Skeleton. In this case, the user will manually label markers after capturing the data and having a defined set of marker labels (MarkerSet) simplifies this process. MarkerSets within a Take will be listed in the Labeling Pane, and each label can be assigned through the Labeling process.
Rigid body and Skeleton assets are the 'Tracking Models'. Rigid bodies are created for tracking rigid objects, and skeleton assets are created for tracking human motions. These assets automatically apply a set of predefined labels to reconstructed trajectories using Motive's tracking and labeling algorithms, and Motive uses the labeled markers to calculate the position and orientation of the Rigid Body or Skeleton Segment. Both rigid body and skeleton tracking data can be sent to other pipelines (e.g. animations and biomechanics) for extended applications. If new skeletons or rigid bodies are created during post-processing, the take will need to be reconstructed and auto-labeled in order to apply the changes to the 3D data. ↑
