Embedded Files
Actualmente tenemos dos versiones de Motive: tracker y body. Cada una de ellas tiene su llave hardware y es necesario instalar un archivo de licencia en la carpeta E:/disco_local/Program data/ OTI track/licence. Esta carpeta se abre automáticamente escogiendo la opción "Get license folder" que muestra Motive en su apertura, o desde la barra de menú:.
Labelling and Reconstruction of Markersets
Labelling and Reconstruction of Markersets
- Creating a markerset
We must be working with a previously made capture, and switch to EDIT mode.
In the Assets Panel we add a new Markerset and name it
Then we go to the Markersets panel, and add the markers that will be associated to each point and name them
We then go to the Labelling panel, where each marker will appear with a 0% assignment, and we will have a list of unassigned markers. we will have a list of unassigned markers
We have to locate the points in the 3D view, in an instant of time and then switch the panel to QuickLabel mode, with labelling of the point forward and backward in time. Then we select each label and assign it to the 3D points in the main window
Tagged markers change to white in the 3D view and disappear from Unlabeled Markers. We have to look for all the markers that appear in orange at some point in time in order to until there are no more unlabelled markers left.

2. Visualisation and reconstruction
Exit Quickedit mode and select the bookmarks.
Immediately we can display the x,y,z coordinates of each marker.
In the Edit Tools panel we can fill in the gaps where information has been lost. "Find next" finds each of the gaps. "Fill selected" fills them according to the configuration we choose.
Linear interpolation works much better than cubic interpolation. For very long gaps, the "Max Gap Size" parameter should also be touched.
Finally we will end up with all the gaps filled.
Labelling, Reconstruction and Visualization of Skeletons
Labelling, Reconstruction and Visualization of Skeletons
- Skeleton creation
While in live mode, a new skeleton asset is added. In the Builder panel we choose the specific skeleton model to be used.
The person on whom the measurements are to be taken must place all the markers in the indicated positions. He/she must then enter the capture zone. The system will indicate the number of markers detected. When the number of detected markers coincides with the number of markers required, the model can be created. By clicking on the option to create the model, the skeleton will be displayed directly in the perspective view window.
With the skeleton created, motion capture can be performed.

2. Reconstruction and labelling
By using a skeleton, most of the markers will have reconstructed and self-labelled themselves. We can use the same tools as in the case of rigid bodies to correct mislabelled points or swap markers. In this case, it is advisable to do an automatic autolabelling after each change.
As in other modes, the x,y,z positions of the well-labelled points can be seen without problems in the graph view.

Labelling and Reconstruction of Rigid Bodys
Labelling and Reconstruction of Rigid Bodys
- Rigid Body Creation
In Live mode we identify the markers corresponding to the rigid body in the perspective view. Directly from the perspective view we create the rigid body.
In the Assets Panel we can change the name
The different points of the rigid solid are defined in the properties panel. In this panel you can also choose the centre of the rigid solid and the orientation of its axes.
We then go to the Labelling panel, where each marker will appear with a % assignment, and we will have a list of unassigned markers. The operation is similar to that of the markersets, but with the identification of many points done.
We have to locate the points in the 3D view, at an instant in time and then switch the panel to QuickLabel mode, with labelling of the point forward and backward in time. Then we select each label and they are assigned to the points in 3D. This process is the same as creating a markerset.
The labelled markers change to white in the 3D view and disappear from Unlabeled Markers. We have to look for all markers that appear orange at some point in time to tag them, until there are no more unlabeled markers left. After each change of a point, by tagging or deleting it, useful information has been added. A new autolabelling can be requested which will use this information and can speed up the process (This option is not available for markersets).

2. Visualisation and reconstruction
Exiting Quickedit mode, we select the markers and immediately see the x,y,z coordinates of the rigid solid.
Unlike with the Markersets, we now also have the option to view the orientations. In the Graph View a user layout is already defined, called orientations, which includes RotX, RotY, and RotZ.
