|  | Move 3D Object.\* The *Edit Skeleton*  must be enabled to use this tool. This tool allows users to click on a skeleton bone segment and apply translation along its x,y,z of the segment axis or the global axis. This is featured only in post-processing of a recorded 3D data. When the change is made, the segment hierarchy will be modified and reflected on exported skeleton bone data but the marker locations will remain the same. |
|  | Rotate 3D Object.\* The *Edit Skeleton*  must be enabled to use this tool. This tool allows users to click on a skeleton segment and apply rotations about x,y,z of the segment axis. This is featured only in post-processing of a recorded 3D data. When the change is made, the segment hierarchy will be modified and reflected on exported skeleton bone data but the marker locations will remain the same. |
|  | Scale 3D Object.\* The *Edit Skeleton*  must be enabled to use this tool. This tool allows users to click on a skeleton segment and re-scale its length. This is featured only in post-processing of a recorded 3D data. When the change is made, the segment hierarchy will be modified and reflected on exported skeleton bone data but the marker locations will remain the same. |
|  | Assign Markers to Skeleton.\* When this feature is enabled, you can associate markers to a skeleton segment by selecting them altogether. For more information: Skeleton Tracking page |
|  | Local Axis.\* When applying translation, rotation, or scaling onto a skeleton segment, the changes will be applied in respect to the local coordinate axis. This option is mutually exclusive with Global Axis. |

Perspective view visual aids
Opens a context menu to enable or disable visual aids for the perspective view, which includes the following:
Assigned Markers: Show/Hide expected, or assigned, marker positions that allow auto-labeling of markers for tracking assets.
Marker Count: Show/Hide reconstructed and selected marker counts at the bottom-right corner of the view.
Marker Labels: Show/Hide marker labels for the selected markers.
Marker Label Colors: Show/Hide unique marker color for better distinguishing multiple marker labels within an asset.
Marker Sticks: Show/Hide marker sticks for skeleton assets.
Marker History: Show/Hide marker trajectory history trail.
Two Marker Distance: Show/Hide marker distance information that appear when two markers are selected from the 3D view.
Three Marker Angle: Show/Hide three marker angle that appears when three markers are selected from the 3D view.
Tracked Rays: Show/Hide Tracked Rays from the view. Tracked rays are the marker centroid rays (available only in 2D data) from each camera that contributes to the 3D reconstruction.
Untracked Rays: Show/Hide Untracked Rays from the view. Untracked Rays are the marker centroid rays (available only in 2D data) that are seen by each camera but does not contribute to the 3D reconstructions because the reconstruction requirements, usually the ray count, are not met.
Missing Rays: Show/Hide Missing Rays from the view. Missing Rays are the expected marker centroid rays (available only in 2D data), based on reconstructed 3D points, that is missing from the 2D camera view.
Capture Volume: Show/Hide virtual scope of the tracking capture volume based on the camera calibration.
Coordinate Axis: Show/Hide global coordinate axis at the left-bottom corner of the 3D view.
Camera Labels: Show/Hide camera labels from the 3D view.

|  | Toggle to show/hide markers from the perspective view. |
|  | Toggle to show/hide skeletons from the perspective view.\* |
|  | Toggle to show/hide rigid bodies from the perspective view. |
|  | Edit Skeleton\*. When this feature is enabled, users can translate, rotate, and rescale individual bone segments of skeleton assets within a recorded 3D *Take*. |
|  | Symmetrical bone length\* When this feature is enabled, any modifications on bone lengths are applied symmetrically on both left and right side of a skeleton. |
|  | Symmetrical bone orientation\* When this feature is enabled, any modifications on bone orientations are applied symmetrically on both left and right side of a skeleton. |
*\* signifies this option is only available with Motive:Body.*
**Two Marker Distance**
In the 3D perspective view pane, you can quickly check 3D distance between a set of two markers. First of all, make sure to enable the Two Marker Distance feature under the visual aids, and select two markers to measure the distance from. Then, the corresponding displacement (in mm) between two markers will be displayed on the view port.
**Three Marker Angle**
Likewise, an angle formed by three markers can also be examined. Make sure the Three Marker Angle display feature is enabled under the visual aids. When this feature is enabled, the respective angle (in degrees) will be measured and displayed over the viewport when a set of three marker is selected from the scene. Note that the selection order will determine the vertex point when measuring the angle.
### Camera Preview
2D Camera Preview mode.

Visual aids available for 2D camera preview
Shows a list of visual aids for the 2D Camera Preview which includes the including:
Camera Info: Show/Hide camera specific information, including camera models, camera setting values, time, data transfer rate, frame ID, and sync methods. For Prime series cameras, image board temperature information will also be available. If there is any synchronization or hardware issues, they will also be indicated in the camera info.
Marker Coordinates: Show/Hide (x,y) coordinate information for the reflections that satisfy the 2D object filter.
Marker Centroids: Show/Hide centroid crosshairs for the reflections that satisfy the 2D object filter.
Marker Boundaries: Show/Hide square intrusion boundaries for the detected markers. Multiple reflections sharing, or intruding, the boundary is considered as one object.
Marker Circularity: Show/Hide circularity value label for detected reflections. The label will appear red if the reflection does not satisfy the 2D filter setting.
Marker Aspect Ratio: Show/Hide aspect ratio of the intrusion boundaries. The label will appear red if the reflection does not satisfy the 2D filter setting.
Marker Size: Show/Hide number of pixels involved in each reflection. The label will appear red if the reflection does not satisfy the 2D filter setting.
Marker Label: Applicable when tracking active LED markers. Show/Hide label ID for each marker.
Reticles: Show/Hide marker reticles to indicate where the reconstructed markers are located in respect to the camera view.
Masks: Show/Hide masked regions in each camera view.
