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.

  • 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.

View SymBoneLengthOri 111.png
Symmetrical bone length and orientation* When this feature is enabled, any modifications on bone lengths and 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.

    • Properties: Opens the Properties pane and lists out associated properties of a selected rigid body.
    • Reset Pivot: Repositions the rigid body pivot point at the center of a rigid body.

    • Remove Selected Markers From Rigid Body: Removes the selected rigid body marker position from the rigid body asset definition. In order to do this, Enable Skeleton Assigned Marker Selection Viewport15.png, must be enabled to select the rigid body marker definition.


    Selection: Skeleton[edit]

    Viewport context menu when a skeleton is selected

    The following context menu appears when a skeleton asset is selected in the perspective view.

    • Skeleton: Contains options for a skeleton asset

      • Remove All Skeletons: Removes all skeleton assets from a capture.
      • Remove Selected Skeletons: Removes selected skeleton assets from a capture.
      • Remove Selected Markers from Skeleton: Removes selected skeleton marker from the skeleton asset definition. In order to do this, Enable Skeleton Assigned Marker Selection Viewport15.png, must be enabled to select the skeleton marker definitions.


    Selection: Force Plate[edit]

    Camera preview context menu

    The following context menu appears when a force plate is selected in the perspective view.

    • Set Position: Repositions a force plate asset according to the location of the calibration square. This is used to calibrate the position of a selected force plate within Motive. For more information: Force plate setup page.
    • Zero (all): Zeroes, or tares, all selected force plates.
    • ReSynch (all): For triggered synchronization protocols, (e.g. force plates that syncs using the record trigger), this feature re-synchronizes force plates with the camera system. This will remove any sync offsets that may have increased gradually since the trigger.
