From the accordion menu you can optimize rendering and display fluidity of your headset by checking or unchecking the parameters below:

From this icon you will find the above rendering parameters as well as the operating status, model, and manufacturer of the device, plus the following parameters.

The Rendering Mode allows you to select the appearance of your product:

The Eye separation is initialized with the default value of the headset, however, this value can be modified in the dedicated field.

The HMD render scaling slider is useful for zooming out the world so that your model fits the dimensions of the screen of the VR headset.

From the drop-down menu you have access to the following features to render in your device.

Icon	Action	Description
	Hide rendering window units	Hides the window of each rendering unit (gray icon) to configure their graphics card for example. Note The window for each rendering unit is displayed by default.
	Unit windows always on top	Keeps the windows of the rendering unit in the foreground among all the windows of the Microsoft Windows® operating system. Note Disabled by default.
	Eye	If the display of the eyes is reversed by a projector (frequent with certain stereoscopic configurations), click on to switch between the left and right displays. Note Disabled by default.

Click on this icon to open the windows rendering configuration of your device in the advanced system settings (Windows configuration).

Please refer to the chapter titled Windows configuration to set up rendering in your device.

The VRPN device management allows you to add, configure, and delete a VRPN device.

Accel VR supports ART, VICON, and NaturalPoint tracking systems.

Accel VR Pilot establishes the link between the render units and the trackers, gamepads, etc ... The connection is made via a local server.

Install ART or VICON equipment according to the manufacturer's recommendations. Accel VR Pilot 2020.1 must be linked with the machine on which the VRPN server of ART or VICON is installed.

The important parameters to remember from a VRPN server are: its IP address, the main tracker name (in the case of tracked glasses), and its index.

The VRPN server must receive information from the tracker(s) (please refer to the manufacturer's user documentation).

3D glasses

To use peripherals allowing navigation in the 3D scene (Logitech® controllers, Xbox 360® controller for Windows®, etc.), simply connect them to the machine on which Accel VR Pilot 2020.1 is running and install the peripherals drivers. A space mouse may also be used too.

SpaceMouse® Pro

This icon opens the VRPN device plugin settings window.

VRPN Manager

VRPN Manager consists of two parts:

Please refer to the manufacturer documentation of the selected device to know the IP address of the Tracker Server. The following drop-down menu provides to Accel VR Pilot 2020.1 by VRPN protocol the current position of the tracked devices. The digit represents the sensor ID of ART tracking systems. It is normally worth 0 with Vicon systems.

Select the tracker orientation with the following arguments (Y_UP, Z_UP_X_LEFT, Z_UP_X_RIGHT, Z_UP_Y_LEFT, Z_UP_Y_RIGHT) depending on the manufacturer specifications. If the Y_UP convention is not used by default by the tracking system, data provided will be converted by the tracking framework.

If your VRPN device has an analog stick or buttons, the Analog-stick and Buttons boxes will allow you to configure them. Select the Use tracker server radio button if your device is communicating on the same tracking server configured earlier in the VRPN manager. If, on the contrary, the VRPN device does not have an analog stick and buttons such as tracked glasses, select None in both boxes.

In case your device does not communicate on the same tracking server, you then need to associate an analog stick or buttons on a separate server. To do this select the button Use a separate server. Then enter the server address in the field Dedicated server.

The box Information / configuration allows you to adjust the horizontal orientation of the device and make adjustments regarding its positioning in space thanks to the fields X, Y, Z coordinates.

Expand the accordion menu and then click the Correct trapezoid button to calibrate the projection areas of the CAVE.

See details in the Operating principles chapter to understand how Accel VR works with a CAVE.

Areas outside of the test pattern will always be displayed in black to restrict the projection to the intended screen.

In an immersive system using walls, the observer is often unaware of the edges of the observation area and of the placement of the screens. To prevent the observer from running into the screens, a proximity warning is available.

With the accordion menu you can directly activate or deactivate the proximity warning option.

It is possible to modify the default settings of the proximity alert such as its Minimum distance, its Maximum distance or its Color by clicking on this icon .

The proximity warning colors the display and shows a grid with the color of your choice whenever an obstacle (the screen) is detected within a defined zone around the observer's head (Minimum distance and Maximum distance). This zone is defined in terms of the distance from the center of the observer's head.

From the accordion menu you can optimize the rendering by checking or unchecking the parameters below:

From this icon you will find the below rendering parameters as well as the operating status, model, and manufacturer of your device, plus the following parameters.
