External Monitor Settings

This page explains how to configure Portalgraph when using a 3D projector or similar device connected to your PC. When using a large screen such as a projector, a VIVE Tracker is used for viewpoint tracking.

Press F12 while the Portalgraph application is running to open the settings screen.

In the View Count field on the right, enter the number of screens on which to display the Portalgraph view, then enter the display number for each screen (1 = main display, 2 and above = sub-displays; this depends on your environment).

Click "Apply" to apply the values — changes will not take effect unless you click Apply. If the screen you are using changes, you will need to restart the application.

Offset and Scale do not normally need to be edited. Skip the following unless you need to restrict the display area. Use these settings if you want to display the image in only part of the screen. Offset uses (0, 0) as the bottom-left and (1, 1) as the top-right; Scale ranges from 0 to 1 (same as Unity's camera viewport).

From the 3D dropdown, select the 3D mode that matches your 3D projector or other display device.

• Side-By-Side — Left-right split 3D

• Top-And-Bottom — Top-bottom split 3D

• Anaglyph — Red-blue 3D glasses. The color split method can be selected from the dropdown on the right.

• No 3D — No 3D output

• 2 outputs — Splits the left-eye and right-eye images across two separate video outputs. The left-eye image is output to the screen currently being configured, and the right-eye image is output to the screen selected in the sub-display dropdown.

After configuring, use the VIVE Tracker to calibrate the screen. For initial VIVE Tracker setup and calibration, refer to the VIVE Tracker Setup Guide.
