Main Page → Motive Documentation → Assets
- This page covers basic types of trackable assets in Motive. The assets in Motive are used for labeling of reconstructed 3D markers in Motive, and they are managed under the Assets pane which can be opened by clicking on the icon. Each type of asset is further explained in the related pages.
Once Motive is prepared, the next step is to place markers on the subject and create corresponding assets. There are three different types of assets in Motive:
- Rigid Body
The MarkerSet is 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 in post-processing. When doing so, having a defined set of labels (MarkerSet) makes this process much easier. 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.
Assets may be created during both Live (before capture) or Post (after capture, from a loaded TAK) captures.
The Assets pane lists out all assets that are available in the current capture. You can easily copy these assets onto other recorded Take(s) or to the live capture by doing the following:
Copying Assets to a Recorded Take
- Copy and paste assets onto another Take by selecting desired assets on the Assets pane and drag-and-dropping them onto the Take on the Data pane.
Copying Assets to Multiple Recorded Take(s)
- If you wish to copy assets to multiple Takes, right-click to bring up the context menu, and choose "Copy Assets to Takes". This will bring up a dialog window for selecting which assets to move.
Copying Assets from a Recorded Take to the Live Capture
- If you have a list of assets in a Take that you wish to import into the live capture, you can simply do this by right-clicking on the desired assets on the Assets pane, and selecting Copy Assets to Live.
For selecting multiple items, use Shift-click or Ctrl-click.
Assets can be exported into Motive user profile (.MOTIVE) file if it needs to be re-imported. The user profile is a text-readable file that can contain various configuration settings in Motive; including the asset definitions.
When the asset definition(s) is exported to a MOTIVE user profile, it stores marker arrangements calibrated in each asset, and they can be imported into different takes without creating a new one in Motive. Note that these files specifically store the spatial relationship of each marker, and therefore, only the identical marker arrangements will be recognized and defined with the imported asset.
To export the assets, go to Files tab → Export Assets to export all of the assets in the Live-mode or in the current TAK file. You can also use Files tab → Export Profile to export other software settings including the assets.
Important Update Note TRA/SKL files can still be imported into Motive, but they will be deprecated from the next release. This functionality will be replaced with the motive profile functionality. Starting from Motive 2.1, you can export just the Asset definitions into a Motive profile (*.MOTIVE) and re-import them in whenever necessary. In Motive 2.1, you will no longer be able to export out TRA/SKL files.
