2D Display Options

Camera Health Info

Displays various assessments of camera health over the 2D camera views, for troubleshooting performance issues. If any performance issues is detected, corresponding problem will be listed at the bottom of the 2D camera view.


When enabled, renders a crosshair on top of the 2D camera views, which can be useful for camera aiming.


Enables displaying masked area on the 2D camera views, in red.

Backproject Markers

Enables markers selected from the 3D Perspective View to be also highlighted with yellow crosshairs in the 2D camera view, based on calculated position. Crosshairs that are not directly over the marker tend to indicate occlusion or poor camera calibration.

Marker Filter

When enabled, filtered reflections will be labeled with the corresponding object filters in the 2D camera view.

Marker Coordinates

Displays 2D coordinate of the detected object centroids within the captured image, in pixels.

Marker Centroids

Displays crosshairs on marker centroids in the 2D view.

Marker Boundaries

Displays a box around each marker, indicating its calculated edges after the brightness threshold.

Marker Circularity

Displays the roundness of an object. A value of 1 indicates maximum roundness, while a value of 0 indicates no roundness.Pixel inspector enabled in 2D view

Marker Aspect Ratio

Displays the ratio of object width to object height as a decimal, resolved to .01 pixel.

Marker Size

Displays the area of the object in pixels, accurate to .01 pixel.

Marker Label

Displays the pre-identified labels assigned to 2D objects for initial tracking from frame to frame.

Pixel Inspection

Displays X,Y coordinates for 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.

Texture Streaming

Disables or enables texture streaming of reference videos on the 2D camera viewport.

Visual FPS Target

Sets a maximum frame display rate for the 2D camera view.

Background Color

Selects the color to display in the viewport between camera panes.

Camera Info

Enables text overlay of pertinent camera information on the 2D Multi Camera view panes. Displayed information includes image mode, time, data rate, frame ID, visual FPS, number of objects, camera serial, exposure value, threshold value, IR intensity value, internal temperature, and camera sync mode.

Distortion Map

Show Distortion

Displays each camera’s lens distortion map.

Overlay Color

Selects the color of the lens distortion map display.

Overlay Transparency

Selects the transparency percentage for the lens distortion map.

Overlay Resolution

Selects the level of details for displaying the lens distortion. More specifically, it sets number of distortion grids on the width and height of the distortion map.

Show as Predistortion

Selects whether the map is shown as pre-distorted or distorted.

Multi-Camera 2D Display

Display Mode

Sets levels of details for the markers displayed in the multi-camera 2D view. Available modes are Frame Buffer, Marker Centers, and Automatic LOD modes. Default is Automatic LOD.

  • Automatic LOD switches between Frame Buffer mode and Marker Centers mode depending on the zooming of the 2D camera view, or the LOD threshold setting.

  • Frame Buffer mode pushes the entire camera frame to the video card for scaling and display. It provides verbose information on detected reflections and centroids, but it is data intensive at the same time.

  • Marker centers mode merely defines a white circle of the rough size and shape of the marker as it would appear. More specifically, it displays the reflections by its size and location and is significantly less hardware intensive.

Pane Gap

The distance between 2D Multi View camera panes, in pixels.

LOD Threshold

The size, zoom percentage, at which the system switches between Marker Centers and Frame Buffer mode.

Raster Priority

Defines the update rate for the camera pixel data shown in the 2D camera views. The priority value ranges from 1 - 6, and a higher priority indicates a higher rate of update.

3D Display Options

Displays marker labels for selected markers in the perspective view.

Show Timecode

Enables or disables timecode values displayed on the 3D viewport. Timecode will be available only when the timecode signal is inputted through the eSync.

Video Overlay Display FPS

Controls of often scene video overlays are updated for display.

Undistort Video Overlay

Removes distortions from the grid when displaying the video distortion overlay in the reference video.

Show Tracked Rays

Displays tracked rays in the view port. Tracked rays are marker rays with residual values less than the Maximum Residual setting from the reconstruction pane. In other words, tracked rays are marker rays that are contributing to 3D reconstructions.

Show Untracked Rays

Displays the untracked rays in the view port. Untracked rays are the rays which start from each camera and goes through the detected 2D centroids, but fails to be reconstructed in the 3D space. When there are several untracked rays in the capture, it is usually a sign of bad calibration or extreme reconstruction settings.

Show Missing Rays

Displays the missing rays in the view port. Missing rays form when tracking a rigid body or a skeleton, and it indicates expected marker rays that are not detected from the camera view but expected from the rigid body or the skeleton solve.

Show Two Marker Distance

Enabling this will display distance between two markers in the Perspective View pane. Two markers must be selected to calculate the distance.

Show Three Marker Angle

Enabling this will measure an angle formed by three markers in the Perspective View pane. Three markers must be selected, and the calculated angle will follow the selection order. When all three markers are selected at once, the widest angle will be measured.

Show Marker Colors

When labeled, each skeleton marker is colored as defined in the corresponding markerset template. Enabling this setting will color the markers for better identification of the marker labels.

Show Marker Sticks

Setting this to true will show marker sticks on skeleton assets for clearer identification of skeleton markers and segments in each individual actor. Setting this to true will reveal marker sticks in 3D data.

Calibration Pane Options

This section covers through the display options for the calibration features. In previous releases, these options existed in the Calibration pane.

Panel Output

Default: Standard. Decides whether the calibration process is displayed in a list format or a grid format. Grid format allows more camera progresses to be seen in the pane.

Status Ring

Default: Visualize. Enables the Status Indicator Ring to glow during calibration in order to display the wanding process.

Solver Visualizations

Default: Show. This toggles the display of wand samples and point cloud calibration visuals in the 2D and 3D view. If you're running on a lower end machine or graphics card with a large system, it is best to turn this feature off. The visual display will in fact eat up some computing power you may want reserved for getting quicker calibration results.

Lens Distortion

Default: Show. Use this to toggle the display of the lens distortion solution results in the 2D view. The lens distortion will be represented by a square grid that maps the distortion.


Default: Show. This toggles the display of the cameras during the solve.

Wanding Projection

Default: Show. This toggles the display of wand samples projected in the 3D view. Turn this off if you're calibrating a very large system.

Projection Error

Default: Show. This toggles the display of error, reported as a color in the projected wand samples and markers. The wand samples will have a color between blue (good sample) and red (poor sample). Make sure the samples you collect are mostly good samples. As will all visual feedback, it may be a good idea to turn this off if you're calibrating a larger system.

Residual Error

Default: 6 mm. Set the tolerance for the reported error in the projected marker sample during calibration.

Wand Error

Default: 8 mm. This sets the tolerance for the reported error in the projected wand sample.

Sample Spacing

Default: 1. Use this to increase the spacing between displayed samples that are projected in the 3D view. Increasing this will skip more samples but will make the visual wand projections easier to see.
