Introduction
Use zView to share a zSpace session. Normally, only the person at the zSpace can see the application in
stereoscopic 3D. zView projects the user’s experience onto a screen or a second monitor. You can use
zView to share the application in real time, record the zSpace session, or both.
Modes
zView provides two different modes:
• Augmented Reality View shows the application from a fixed viewpoint, without head tracking.
This mode requires a camera.
• Standard View shows the application with head tracking. Use this view to demonstrate how the
application adjusts the viewpoint as the user’s head moves. This mode does not require a
camera.

Requirements
zView has minimum requirements for Standard view, and additional requirements for Augmented
Reality view.
Standard View requirements:
• zSpace System Software
• zSpace 200: Version 4.0 or later
• zSpace 300: Version 5.0 or later
• zView-enabled application
• A second display for the zView application window
Augmented Reality View additional requirements:
• A webcam that supports HD resolutions (1280x720 or 1920x1080) at 15 frames per second (FPS)
or higher. zView works well using the Logitech C920 and Microsoft LifeCam Pro webcams.
• A zSpace camera mount or a tripod.
You can purchase a zView kit from zSpace that includes a webcam and a camera mount to attach the
webcam to the zSpace display.
The zSpace application you want to view must be enabled for zView. All zSpace STEM applications are
enabled and have zView controls embedded in them. If you are developing your own application, you
can enable it using the zView Unity plug-in.

Set Up zView
zView runs on the same hardware required for zSpace applications. You must attach a second monitor
to use zView. You need a webcam to share and record zSpace sessions.
Connect a Second Display
You can connect the zSpace computer to a second monitor, a projection screen, or a TV.
1. Connect the second display using a DVI, HDMI, VGA, or DisplayPort connector as needed.
2. Open Windows Screen Resolution from Control Panel > Display > Adjust Resolution or right-
click on the desktop and select Screen Resolution.
3. Make sure that the Screen Resolution dialog box shows two displays in the same left-to-right
order as the displays are physically placed. For example, in the following figure, the zSpace
display is to the right of the second display.
Note: When connecting a secondary display, Windows sometimes arbitrarily changes the
resolution of your zSpace system to something other than 1920x1080. After connecting the
second display, verify that the resolution of your zSpace is 1920x1080 to avoid display problems.

4. If the displays are not arranged correctly, click and drag the zStation display to the number 1
position.

6. Click Apply to test the settings.
7. When the settings are correct, click OK.
For more information, see Display Configurations - Managing Multiple Displays at zSpace Support.
Set Up the Camera
If you are only using the Standard View, you can skip this section.
Refer to the documents for your system when setting up the tripod or camera and mounting kit.
Plug the webcam USB cable into your PC. On the zSpace 300, use the USB 2.0 port on the back of the
zSpace.
Note: On many PCs, the webcam functions best in a USB 2.0 port instead of a USB 3.0 port. For
information about identifying USB ports, see Identifying USB 3.0 Ports at zSpace Support.

Configure zView
When you start zView, if it does not appear on your secondary display, drag the zView window to that
display.
• If you are using Standard View, you do not need to configure zView.
• If you are running zView in Augmented Reality View, which includes sharing the head-tracked
experience, you must configure zView to work with your camera. You can configure zView from
the Setup menu.
Augmented Reality View
Make adjustments to the camera position during Setup. This includes making sure that the camera
captures the user’s expression, if desired, and that lighting does not cause a glare on the zSpace. If you
adjust the camera later, you must run Setup again.
Note: Make sure the camera is connected to the zSpace and facing the zSpace display.
Follow these steps to run Setup:
1. Start zView.
2. Click Setup to start the configuration.
3. From the USB Camera Setup dialog box, make sure the camera is listed. Choose the
recommended resolution.
4. Click Next to continue.

5. The zView Display Detection dialog box appears and is semi-transparent.
Six test patterns appear on the zSpace. Check the zView window. At least two markers must be
outlined in red before you can continue. zView also outlines the zSpace screen in red.
6. For the best results, adjust the camera until zView detects all six markers and the outline turns
green, then click Next.
Note: If zView cannot detect the display, make sure the camera view includes all four corners of
the zSpace display. Next, try lowering or adjusting the lights to avoid glare on the camera and
zSpace.
7. Click Finish.

Adjust the Overlay
You can adjust how the zView-enabled application displays in Augmented Reality View.
Complete the following steps:
1. Open a compatible application in zView.
2. When the application appears in the zView window, select Tools > Show Display Bounds. This
makes it easier to check the fit of the zSpace display in zView.
3. In zView, select Tools > Adjust Overlay.
4. If the application does not fit in the zView window correctly, make the following adjustments:
o To move the display right or left, enter a positive or negative number in the X Offset
text box.
o To move the display up or down, enter a positive or negative number in the Y Offset
text box.
o To adjust the size of the display, enter the percentage to scale the display as a decimal
number in the Scale field.
The following figure shows an overlay out of position.
zspace.com
The following figure shows an overlay correctly adjusted.
5. When the overlay is correctly adjusted, hide the display bounds by clearing the Tools > Show
Display Bounds menu option.
6. Click OK.
When you run zView again, the system prompts you to reuse the current settings or run the Setup
Wizard again.
If the application you are running includes zView controls, the next time you run the application you can
launch zView from within the application. However, if you move the camera you must repeat these
configuration steps.
When you are done configuring zView, you can share or record a zSpace session. See the next section
for more information.
