Preview Window

Depending on the options in the section "Preview Settings" this window shows either a camera's image (in grayscale, segment or tracking mode) or the virtual 3D space with all cameras and markers inside. To navigate in the 3D space use the middle mouse button (wheel): Scroll = Zoom, Drag = Pan, ALT+Drag = Rotate. More 3D rendering settings...

If a mask is set up, it is displayed as an blue overlay.

If a tag is found, it is displayed with...
- its ID if possible (here: 10)
- a white circle indicating the maximum speed (see "2D Tracking Settings")
- another circle underneath the white one, if you change the default minimum distance to another tag (see "2D Tracking Settings")
- a white cross indicating the tag`s position with the added damping time (see "Prediction Settings").

Please see the below table for detailed information about "Grayscale / Segment / Tracking".

Show Info

This displays the Information in the left upper corner. The frame rate (FPS) depends on the mode chosen: the maximum rate is reached only in tracking mode and is lowered for the other modes. The Point Count informs about the number of valid areas. All valid areas are analyzed whether they hold an ID. If so, their tag ID and circles are displayed.

Show Origin Markers

This displays a red circle at the location from a origin marker when the "Mouse Mode" of the "Camera XYZ Calibration" was used.

Scaled Preview

This toggles between a scaled view of 640x480px and the camera image in its original size (e.g. for the s250e model: 832x832px). A non-scaled view will be shown 1:1 and with scrollbars.

Show Cross Hair

This displays a horizontal and vertical line at the mouse pointer's position. Under certain circumstances it might be useful to see a crosshair overlay in the preview. The center of the image is marked as well as the size of a quarter of a frame. For instance, it is useful for the "Camera Lens Calibration" process.
