1. Before Starting PHOTON

Requirements for PHOTON

Windows 7 (and above)

NVIDIA GPU

1.1 PHOTON Installation

After retrieving the installer (.exe) — downloaded from our website, or sent to you by a PHOTON Specialist — double click on the (.exe) file. (You might have to answer a Windows security question.

Choose the destination folder (it is usually C:\VYV or P:\VYV).

Click on the [Install] button, wait for the installation process to complete, and then click on the [Close] button.

1.2 VYV Network Assistant Installation

The VYV Network Assistant is an external tool that runs independently of PHOTON. It allows you to:

• manage the version of PHOTON you are using;

• install and uninstall different versions of PHOTON;

• manage your PHOTON Projects;

• start PHOTON with arguments (for example, no UI or no splash screen on startup);

• restart PHOTON;

• quit PHOTON;

• reboot the server;

• shutdown the server.

The VYV Network Assistant makes it possible to automatically launch a specific version of PHOTON and start a specific project after Windows boots.

1. After retrieving the installer (.exe) — downloaded from our website, or sent to you by a PHOTON Specialist — double click on the (.exe) file. (You might have to answer a Windows security question.)

2. Choose the destination folder (it is usually C:\VYV or P:\VYV).

3. Click on the [Install] button, wait for the installation process to complete, then click on the [Finish] button. A prompt window will open right away, asking you to start the VYV Network Assistant.

1.3 Network Configuration

PHOTON servers need to be assigned static IP addresses and must reside on a dedicated network. All of your servers should be connected to a network switch.

Make sure your servers and network switch share the same network prefix and subnet number (the first 3 octets in the IP address).

The network switch’s host number (last octet in the IP address) should be 1. The network switch will probably use a browser-based interface to allow parameter modifications. The host numbers for the servers can range from 2–254.

Make sure that the network interface you are using is the first one being accessed by Windows’ network services. In order to do this:

1. Go to {Control Panel > Network and Sharing Center > Change Adapter Settings};

2. Press the [Alt] key to display the Advanced menu;

3. Select {Advanced > Advanced Settings}.

The Advanced Settings window (Adapters and Bindings tab) will display the network interfaces list. You can change the order of the network interfaces by selecting them individually and pressing the up/down arrows.

1.4 Remote Install/Uninstall

After all of the servers are communicating on the same network and have fully functional versions of the VYV Network Assistant installed, you will be able to execute the following actions on all servers from one server using the VYV Network Assistant’s interface.

The PHOTON versions directory is located under …\VYV\PHOTON\versions\...

1.4.1 Install a new version of PHOTON

1. Select the servers you want to install the new version of PHOTON onto by checking the boxes located on the left side of the Systems list.

1.5 Project Configuration

Project configuration will allow you to select which version of PHOTON will run on your Server Group. It will also allow you to create new PHOTON Projects or load previous ones.

A PHOTON Project consists of an independent set of folders that contain important files such as media content, 3D models, saves, and various configurations targeting network and third party hardware. Keep in mind that a new Project will not have access to the files used in previous Projects.

Once you have selected the desired configuration options (see below), press [Apply] to propagate the changes over the network or [Cancel] to discard them.

Configuration Procedure

1. Select the servers you want to configure by checking the boxes located on the left side of the Systems list. Project configuration will be pushed via the network to all of the selected servers.

2. When selected, the servers will be identified by a green check mark. The server you are using as the control interface will have (LOCAL) in front of its name.

3. Select {Tools > Configure...} from the menu bar or press [Alt+C] to open the System Configuration pop-up window.

4. Select PHOTON in the {Product} dropdown menu.

If you want to create a new PHOTON Project:

• select {New…} at the top of the {Project} dropdown menu;

• type the name of your Project in the text box.

If you want to load an existing PHOTON Project:

• select the Project you want to use from the {Project} dropdown menu.

Launch PHOTON with Arguments

An argument instructs PHOTON to perform special operations when the program is launched.

Arguments can be selected in the System Configuration window.

1. Select {Tools > Configure…} from the main menu or press [Alt+C] to open the System Configuration window.

2. Arguments can also be manually typed into the Arguments text box, or added by pressing the [+] button. The [+] button will prompt the Command Line Arguments pop-up window.

3. Select the desired arguments from the list by checking their boxes. When selected, the arguments will be identified by a green check mark. This will push the selected arguments to all of the servers via the network.

Available Arguments

Hide User Interface (UI) on Startup

The UI will not appear on startup, but it can be accessed by pressing the [Tab] key. This option might be useful if your server is a Display Master Server and you are using all of its video outputs to display video content.

Keep Taskbar

The Windows taskbar usually disappears when PHOTON launches and reappears when it is closed. Selecting the Keep Taskbar option will make the Windows taskbar available.

Keep Windows 7 Aero

By selecting this option, Windows 7 Aero functionality will not be deactivated when PHOTON is launched. This might impact performance, but Aero simplifies window capture during Teamviewer sessions.

Disable OptiTrack Cameras

Disabling OptiTrack cameras will prevent PHOTON from accessing the OptiTrack library and discovering the networked cameras. This might be helpful in a troubleshooting situation, where the computer vision system needs to be isolated.

Disable Splash Screen

This option will prevent PHOTON’s splash screen from being displayed on startup.

VYV Network Assistant Autolaunch

If you want the VYV Network Assistant to automatically start after Windows launches, check the box in front of “Run Network Assistant on System startup” (a green check mark will appear).

Autolaunch and Shutdown Delays

If you want to delay PHOTON’s launch after the VYV Network Assistant’s boot procedure, change the value (seconds) in the Run Local Target Timeout(s) slider. This could be useful, for example, if you have network latency problems (i.e. the network switch is slow to wake up).

If you want PHOTON to shutdown after the VYV Network Assistant’s launch, change the value (seconds) in the Quit Local Target Timeout(s) slider. This could be useful, for example, if the Project you are working on uses a lot of memory and needs more time to complete a Default Save procedure.

1.6 Graphic Card Configuration

NVIDIA’s Mosaic technology allows you to create a large virtual canvas with all of the displays that are connected by combining them into one large screen. This larger unique canvas reduces the impact on performance when using 2D or 3D applications in a multi-display situation. PHOTON will still be able to identify each video output as an individual screen.

Follow the steps listed below to build a Mosaic display group.

1.6.1 Before Opening the NVIDIA Control Panel

1. Physically connect your video displays (projectors, monitors, LED screens, etc.) to the server.

2. Make sure the video signal goes to all of the displays by changing the Windows desktop color:

   1. Click on the [Windows Start] button and select {Control Panel > Personalization};

   2. Select Desktop Background at the bottom of the window;

   3. Select Solid Colors from the {Picture Location} dropdown menu and choose a bright color;

   4. Press [Save Changes] if you want to keep the color, press [Cancel] if you want to return to the previous color;

   5. You should see bright color in all displays.

1. You can also check the Windows display settings to make sure all of your displays are recognized.

2. Right-click anywhere on the Windows desktop background and select Screen Resolution in the contextual menu, or click on the [Windows Start] button and select {Control Panel > Screen Resolution}.

3. You should see all of the displays that are connected. Display numbering starts at 1.

This window allows you to:

• reorder the screens by drag and drop;

• change the resolution of each screen;

• change the orientation of each screen;

• choose how the screen behaves (it should always be in Extend Mode);

• choose the main display (the one with the Windows taskbar).

Make sure all of your displays are set at a resolution recognized by Windows, and that they are all in Extend Mode. (Make sure the screens are not cloning one another.)

1.6.2 Open the NVIDIA Control Panel

6. Press the [Load EDID] button.

7. You will see a black flash in the connected displays.

8. A pop-up will confirm the Load procedure was successful.

9. Press the [OK] button.

Unload

The Unload tab allows you to remove a Forced EDID from the selected video outputs to regain the original display’s metadata.

1. Click on the Unload tab if you wish to do so.

2. In the Select Connector to Unload EDID list, select the displays you want to unload Forced EDIDs by checking the boxes beside their name.

3. Press the [Unload EDID] button.

4. You will see a black flash in the connected displays.

5. A pop-up will confirm the Unload procedure was successful.

6. Press the [OK] button.Once all of the connected video outputs have the same EDID, go back to Change Resolution. Make sure each display has the same resolution and refresh rate.

1.6.6 Set Up the Mosaic Display Group

Now you are ready to set up your Mosaic display group.

1. Select {Set Up Mosaic} in the “Select a Task…” list under {Workstation}.

2. Click the Create new configuration link. This will open the NVIDIA Mosaic set up window.

Follow the next 5 steps to create your Mosaic display group:

1. Select Topology

1. Select the number of displays you want to include in the Mosaic display group with the help of the dedicated dropdown menu. You must include all of your available video outputs in the Mosaic configuration.

2. Select your Topology — how the displays will be positioned on the grid — with the help of the dedicated dropdown menu. Always use a single row topology (1 X ...) because PHOTON works through horizontal screen spanning.

3. Select the display Orientation with the help of the dedicated dropdown menu. Always use Landscape even if your project includes rear projections or projectors set up in portrait format. PHOTON will automatically manage these cases.

4. If your screens are listed correctly and placed in the right order you can immediately check the box next to “I am using the recommended connections for the selected topology” and press the [Enable Mosaic] button. This will open the “Apply Changes” confirmation window. If the Mosaic display group seems to be set up correctly, click on the [Yes] button. You should be ready to launch PHOTON now. If not, click on the [No] button and go through the next steps.

2. Select Displays

1. All of the available displays listed underneath “Displays for Mosaic” should already be checked. If not, check the boxes next to their names.

2. Select the desired refresh rate in the {Refresh Rate} dropdown menu.

3. Select the desired resolution in the {Resolution Per Display} dropdown menu.

4. Press the [Next] button.

3. Arrange Displays

1. Arrange your displays by dragging them from the top of the panel to the white rectangles located in the bottom section. This will set their placement in the Mosaic large canvas.

2. You can also type the display numbers into the white rectangles and press [Enter]. (Each display is identified by the large number in the top-left corner.)

4. Numbering

As mentioned above, displays are identified by numbers. The numbers indicate the order in which the displays are connected to the graphics card: display #1 is connected to the output port closest to the motherboard, display #2 is connected to the next output port, and so on. This system for prioritizing displays by using numbers that represent their proximity to the motherboard applies to the other output ports as well.

The small-number pairs displayed in the lower-left corner of the displays represented are another element of this prioritization system. The first number (before the comma) represents the hierarchical position of the graphics card (starting at 0). The second number (after the comma) represents the hierarchical position of the output ports on the graphic card (starting at 0).

1. When the displays are in the correct order, press the [Apply] button. An “Applying Changes” loading bar will appear, and you will see a black flash in all of the connected displays. (This might take a while.)

2. An “Apply Changes” confirmation window will appear. Press [Yes] to apply, or [No] to cancel.

3. The upper section of the window, where the drag and drop displays were initially placed, will have changed. A pop-up window should tell you that the “Mosaic is enabled.”

4. You can still reorder the displays by dragging and dropping them, but you will have to go back and Apply Changes again.

5. The Mosaic display group’s maximum resolution will be written near the bottom of the window.

6. Press the [Finish] button. (Don’t press [Next].)

5. Adjust Overlap and Bezel Correction

Do not adjust overlap and bezel because PHOTON will take care of these issues while calibrating.

6. Confirmation

1. The Set Up Mosaic window will have changed, and will present a summary of the current Mosaic configuration. If you wish to make changes, use the [Modify] button or the [Disable] button.

2. You can also find out if the Mosaic display group is recognized in the Windows display settings. Right-click anywhere on the Windows desktop background and select {Screen Resolution} in the contextual menu, or click on the [Windows Start] button to access {Control Panel > Screen Resolution}.

3. You should see a single monitor representing all of the connected displays. It should be #1.

4. Now you have a Mosaic display group and you are ready to launch PHOTON.
