Press the F12 key to open the settings screen.
IPD: The distance between the left and right eyes (in mm). Usually, no changes are needed.
Camera Lock: Check this box to fix the viewpoint. When you press the Position Set button, a countdown will begin, and the viewpoint will be fixed at the coordinates at the end of the countdown.
Tracker Position: Set the face tracking position here. For camera tracking, select EyeCenter. When you click Apply, the dropdown values are applied to eye coordinates and eye rotation.
Tracker App AutoStart : If checked, the designated tracker app specified in the textbox below will start automatically when the application launches. You can select Camera (for webcam tracking) or OpenVR (for VIVE tracker) from the dropdown.
View Count, Screen, Offset, Scale: These settings apply when using Portalgraph on multiple screens or secondary displays. Set the number of screens in View Count and specify the screen number in Screen (the main screen is 1). Use Offset and Scale if only part of the screen is used; the bottom-left corner is offset (0,0). Click Apply to confirm changes. Note: Changing the screen count or screen number requires restarting the application.
Click Next (N) in the main settings screen to open the calibration screen.
Allows selection of the 3D display mode. The available options are as follows:
Side-By-Side: Splits the screen left and right.
Top-And-Bottom: Splits the screen top and bottom.
Anaglyph: Red-blue glasses mode. You can select the color separation method in the dropdown on the right (Dubois works in most cases).
No 3D: Displays in 2D. The dropdown on the right lets you choose between the right-eye and left-eye views.
2 Outputs: Outputs the right-eye view to a separate output terminal. Use the dropdown on the right to select which screen to output to.
Clicking Camera in the calibration screen opens the camera tracking calibration screen.
If the camera is positioned directly above the center of the screen, facing straight forward, and your PC screen has a 16:9 aspect ratio, simply enter the screen size (in inches) in this screen and click OK to complete the setup.
Screen Size: Enter the size of your monitor in meters.
Camera Position: Select the camera’s mounting position (top, bottom, left, right, or center) from the dropdown, and enter the distance from this position in meters in the text box. The XYZ axes are defined with positive directions as follows: right, up, and away from the screen.
Camera Angle: Enter this if the camera is not perpendicular to the screen.
In the calibration screen, click Camera to open the tracker settings screen.
Screen Size: Enter the size of your monitor in meters.
Screen Angle Correction: If your screen is vertical or horizontal, select this option to automatically adjust the angle during calibration.
Tracker Position: Specify the position to align the tracker with the screen during calibration. Center is usually appropriate, but you can choose a more stable position if using a projector screen where the center is soft, or if using a 3D TV where screen reflections may interfere with tracker stability.
