Introduction
With zView, you can share the zSpace experience with others. Normally, only the person at the zSpace display
can see the application in stereoscopic 3D. While your zSpace system may include non-tracked eyewear for
observers, the display is based on the user’s head position. With zView you can share the experience with a
large audience, without additional eyewear. zView projects the user’s session onto a second display, such as a
projection screen or a second monitor. You can use zView to display the application in real time or record the
zSpace session for later sharing.
zView Modes
zView provides two different modes:
Augmented Reality View shows the application from a fixed viewpoint, without head tracking. This
mode requires a camera. Everything in the camera’s frame, including the user, is shown.

Standard View shows the application with head tracking. This is useful if you want to demonstrate how
the application adjusts the viewpoint as the user’s head moves. In this case, you do not need a camera.
Standard View
zView Requirements
The following are the minimum requirements for Standard View:
zSpace System Software
ozSpace 100: Version 3.x
ozSpace 200: Version 4.0 or later
zView-enabled application
A second display for the zView application window
For Augmented Reality View, you will also need:
A webcam that supports HD resolutions (1080x720 or 1920x1080)
A zSpace camera mount or a tripod
You can purchase a zView kit from zSpace, which includes the zView software, a webcam, and a zSpace camera
mount for attaching the webcam to the zSpace display. If you already have the zView software, you can
purchase the webcam and camera mount separately as well. We have tested zView with Logitech C910 and
C920 webcams.

zView Setup
Connecting to a Second Display
You can connect your PC to a second monitor, a projection screen, or a TV. Use a DVI, HDMI, VGA, or DisplayPort
connection as required by the second display.
1. In the Windows Control Panel, select Display.
2. Choose Adjust Resolution.
3. Check that the Control Panel shows the two displays in the same left-to-right order as your displays are
physically placed. For example, in the window below, the zSpace display is to the right of the other
display.
If the displays are not arranged correctly, click and drag on the window marked (1) or (2) in the Control
Panel.
4. Choose Extend these displays.
5. Make sure the zSpace display is your main display, as shown below.

Setting up the Camera
If you are using Standard View only, you can skip this step.
Before you set up the camera, position the camera mount. This can be the zSpace camera mount, which
attaches to the zSpace display, or it can be your own tripod. Next, plug the camera into your PC.

Mount Camera
Placing the Tripod
Set the camera on the tripod so that the entire zSpace display screen is visible to the camera. Adjust the tripod
so that you capture as much or as little of the user as you want.
Plugging in the Webcam
Plug the webcam’s USB cable into your PC. Refer to the next section for instructions on adjusting the webcam’s
placement.
Note: On many PCs, the webcam functions best in a USB 2.0 port instead of a USB 3.0 port. If you need help
identifying your USB ports, go to https://support.zspace.com and search the knowledge base for an article on
USB 3.0 ports.
Configuring zView
When you first start zView, the Setup Wizard appears. If it does not, select the Tools -> Setup menu option.
Important: Drag the zView window from the zSpace display to your second display.
Follow the instructions below for Augmented Reality View or Standard View.

zspace.com
Standard View
If you are not using a webcam, you must choose Standard View. In the Setup Wizard, select the checkbox for
Standard View, then click on Finish to exit the Setup Wizard.
Setup Wizard
Augmented Reality View
We recommend that you make all adjustments to the webcam’s position while running the Setup Wizard.
Make sure that the webcam captures the entire zSpace display.
Check that the webcam captures the user’s expression, if desired.
Check that lighting does not cause a glare on the zSpace display.
Adjust the display in the zView window, either by moving or scaling it, if needed.
Tip: If the Setup Wizard does not automatically appear, select the Tools -> Setup menu option.
If you adjust the camera later, you will need to rerun the Setup Wizard.
Follow these steps in the Setup Wizard:
1. On the Welcome screen, click Next to start the configuration.

zspace.com
2. Plug in your camera if you have not done so. On the USB Camera Setup screen, make sure your camera
is listed. Choose the desired resolution. Click Next to continue.

3. The zView Display Detection screen appears and is semi-transparent.

4. The zView setup pattern, consisting of six markers, appears on your zSpace display. Check the zView
window. At least three markers must be outlined in red before you continue. zView will also outline the
zSpace display screen. For the best results, make sure the outline is green, indicating the webcam
detects all six markers.
5. For the best results, adjust the camera until zView can detect all six markers and the zSpace display’s
outline turns green, then click on Next.
Note: If zView cannot detect the display, first make sure the camera view includes the entire zSpace
display. Next, try lowering or adjusting the lights to avoid glare on the camera and zSpace display.
6. Start your zView-enabled application. When it appears in the zView window, click Next on the Create
Composite Image screen.
7. Adjust the composite image’s position with Ctrl + Left Mouse Button. Use Ctrl + Mouse Wheel to adjust
the image’s size.
Alternatively, select the Tools -> Adjust Overlay Position menu option.
8. Click on Finish to complete setup.
When you start up zView another time, you will be prompted to reuse the current settings or run the Setup
Wizard again.
If your application includes zView controls, next time you run your application, you can start the application first
and launch zView from within the application. However, if you move your camera, you must repeat setup.

Capturing a zSpace Session
To capture a zSpace session, you generally start zView first, then launch your zSpace application.
Tip: The zSpace STEM applications are integrated with zView. Once you complete configuration, you can start
zView by clicking on the zView icon in the STEM application’s Control Bar. However, the icon is only available
with a teacher login.
The following steps describe how to fine-tune the zSpace display in zView, using the zView application.
1. Make sure you can see your zSpace session in zView. Move the zView window from the zSpace display
to your second monitor if necessary.
2. Select the preferred view: Standard or Augmented Reality. You must have a webcam for the latter.
Choose the Tools -> Modes menu option.
3. Set zView to full-screen mode if desired by selecting the Tools -> Fullscreen menu option. This is
recommended if you are projecting onto a large screen.
4. For Augmented Reality view only:
a. Show the Display Bounds by selecting the Tools -> Show Display Bounds menu option. This makes it
easier to check the fit of the zSpace display in zView.
b. Adjust the fit of the zSpace application in the zView window as needed. Select the Tools -> Adjust
Overlay Position menu option. You can adjust the position and scale. The next two images show the
overlay out of position and correctly adjusted.
c. If the application does not fill the screen, or the image in zView is not centered, you can black out
the zSpace display. To do so, select the Tools -> Blackout zSpace Display menu option.

Recording a zView Session
You can share your zView session in real time, or record it for later sharing. You can record in either Standard
View or Augmented Reality View.
First, start zView, then your zView-enabled application. If you changed the camera position, rerun the Setup
Wizard. Record your session as follows:
1. Make sure you have turned off the display bounds by deselecting the Tools ->Show Display Bounds
menu option.
2. Select the Tools -> Video -> Format menu option to adjust the quality of your recording. A higher quality
also results in a larger video file.
3. Select the Tools -> Video -> Start menu option.
4. The video is saved in Users\Public\Public Videos.
5. When you are done, select the Tools -> Video -> Stop menu option.
Tip: You can also start and stop recording with Ctrl + R and Ctrl + T respectively.

zView-Enabled Software
At this time, the following applications are enabled for zView:
zSpace Franklin’s Lab
zSpace Newton’s Park
zSpace Studio (in development)
zSpace Experience
Cyber Science 3D
Tip: The first three –the zSpace STEM applications –are fully integrated with zView, so you can launch zView
from within the application itself.
If you are a software developer, zSpace provides two options for enabling your application for use with zView:
The zView Unity Package makes it easy for developers to add zView support to their Unity-based
application.
The zView SDK allows developers to add zView support to any application. With the SDK, you can add
zView controls to the application itself.
Contact your zSpace Representative if you are interested in adding zView support to your application.
