Perspective View

3D Perspective View

Toolbar Options

Icon	Description
	Mouse action options Mouse Interactions From this icon, you can switch between different mouse interaction modes in the 3D viewport. You can either use the mouse actions to select objects in the scene, translate, rotate, scale assets, or use the Quick Label mode for labeling. Select: In selection mode, you can any objects in the scene, and their properties will be shown in the Properties pane. Translate: In translate mode, you can apply a translation to rigid body pivot points and skeleton bones. In recorded data, you can also select a group of reconstructed 3D markers in the scene and apply translation along the global x-y-z axis. When the change is made to a skeleton, the segment hierarchy will be modified and reflected on exported skeleton bone data but the marker locations will remain the same. Rotate: In rotate mode, you can apply rotation to rigid body pivot points and skeleton bones. Scale: In scale mode, you can scale the length of skeleton bones or scale the size of the geometry model attached to a rigid body. Quick Label: In QuickLabel mode, you can quickly reassign marker labels in the post-processing of recorded data. Local Coordinates: When enabled, translation, rotation, and scaling changes will be applied with respect to the local coordinate axis of the selected asset. When disabled, all changes will be applied to the global coordinate axis. Symmetric Bones: When enabled, any modifications on bone lengths and orientations are applied symmetrically on both the left and right side of a skeleton.
	Zoom Actions Actions for zooming into a selected object or zooming out to fit all. You can also use "F" and "Shift + F" hotkeys for this.
	Mouse action options Visual Aids Opens a context menu to enable or disable visuals in the perspective viewports. From this menu, you can show or hide markers, marker labels, rigid bodies, skeletons, tracked rays, and more. Visible Show, or hide, markers, cameras, or different types of assets from the perspective view. You can also hide Asset Model markers which are the expected marker positions that allow auto-labeling of markers for the assets. Marker Labels: Show, or hide, marker labels for each marker on the perspective viewport Info: Show, or hide, marker info from the perspective view. Marker info includes x/y/z coordinate as well as the diameter of the marker. Color: When checked, rigid body and/or skeleton markers will be colored according to the color of the related rigid body and/or skeleton asset. Sticks: Show, or hide, skeleton marker sticks from the perspective view. Marker sticks help users to easily interpret the skeleton marker labels from the viewport. History: Show, or hide, marker trajectory history from the perspective view. Distance: Show, or hide, marker distance information when two markerrs are selected in the perspective viewport. Angle: Show, or hide, angle information when three markers are selected in the perspective viewport. Rays 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. Heads Up Display Marker Count: Show/Hide reconstructed and selected marker counts at the bottom-right corner of the view. Coordinate Axis: Show/Hide global coordinate axis at the left-bottom corner of the 3D view.
	Selection Lock This tool locks the camera into the selected object(s) in the 3D perspective view, and the viewport will follow the selected object throughout the capture. For example, you can select a rigid body in the view, lock the selection, focus zoom into the object (Hotkey: F) have Motive follow the object.
	Selection Enables, or disables, selection of specific objects in the 3D view. Only the items checked in the menu will be selectable in the perspective view.

Cameras View

2D Camera Preview mode.

Hotkeys

Function	Default Control
Switch selected cameras to Object mode	O
Switch selected camera to MJPEG mode	I

Zoom	F: Quickly zoom into a selected camera(s) in the view. Shift + F: Quickly zoom out to fit all of the cameras into the view.

Toolbar Options

Icon	Description
	Pixel inspector enabled in 2D view Mouse Actions From this icon, you can switch between different mouse interaction modes in the camera viewport. In addition to simple Select mode, you can switch to the Pixel Inspector mode to check the brightness of individual pixels in the grayscale mode for inspecting the camera view, or you can also add/remove masking from the camera view. Pixel Inspection In pixel inspection mode, the viewport displays X,Y coordinates of the cursor location when hovering over a camera, and pixel brightness for selected pixels when a region is drag-selected. Inspecting pixel brightness can be useful during camera focusing, tuning, and aiming.
	Zoom Actions Zoom to All: Zooms all cameras to fit the pane. (default hotkey: Shift + F) Zoom to Selection: Zooms into selected cameras to fit the pane. (default hotkey: F)
	Camera viewport visual aid options Visual Aids Show or hide additional camera information from the camera viewport. Reticles: Show/Hide marker reticles to indicate where the reconstructed markers are located in respect to the camera view. 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. Markers Coordinates: Show/Hide (x,y) coordinate information for the reflections that satisfy the 2D object filter. Centroids: Show/Hide centroid crosshairs for the reflections that satisfy the 2D object filter. Circularity: Show/Hide circularity value label for detected reflections. The label will appear red if the reflection does not satisfy the 2D filter setting. 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. Labels: Shows whether the markers detected in the camera view is passive retroreflective marker or active markers. When the camera is detecting an active LED marker(s) corresponding label ID for each marker will be shown.
	Camera Masking Settings Using the masking settings context menu, you can re-apply auto-masking feature, clear masks, and/or perform other actions related to applying masks in the camera view. Mask All: Apply auto-masking to all of the connected cameras. Mask Selected: Apply auto-masking to only the selected cameras. Masking is Additive: When this is checked, all of the masks will be applied additively over the existing masks. Clear All: Clears all masks from the camera view. Clear Selected: Clears masks from selected cameras only.

Reference View

The Reference View mode is used to monitor captured videos from the reference cameras. In order to view the reference view, the cameras must be recording either MJPEG, grayscale, or color video mode (Prime Color). In this mode, cameras, markers, and trackable assets can be overlayed over the reference view. To monitor the reference view, select one of the cameras and use Number 3 hotkey to view from the selected camera. This is a good way of monitoring events during the capture. All of the assets and trajectory histories under the Perspective view pane can be overlayed on the reference videos from this pane.

Rigid body overlayed on reference view.
Skeleton and force vector overlayed on reference view.
Selecting reference view from the viewport options. Hotkey for this is 3 when a camera is selected.

Export

Referece video can also be exported from Motive with the asset overlay. To export, simply right-click on the Take that contains reference videos. Then select Export Video to export the video files. Then in the export options, you can select which assets to overlay in the video.

Exporting recorded video from Data pane.
Overlay options shown in the video export dialog window.
