HD2 - G-Ball Element - Windows


VBOX Video HD2 software comes supplied with a library of g-ball elements. The user also has the option to create their own G-Ball using PNG, JPEG or BMP image files.


Adding a supplied G-Ball element

Open the G-Ball library by clicking the ‘G-Ball’ icon from the top menu bar.

A drop down menu will then appear, allowing a G-Ball to be selected from the library. Clicking on a chosen G-Ball will load it into the scene.

Note: Hovering over any of the g-ball thumbnails will cause a larger preview of the element to appear.

Selecting the 'Filter' drop down on the left enables you to filter the G-Balls shown between default and custom created.


Once a G-Ball has been added to the scene, it can be clicked and dragged to the desired location. 

G-Ball elements within the library will have pre-defined settings. These settings can be changed as shown here.


Creating a new G-ball

When creating a new G-ball element, an image for the G-ball background is required. A recommended size for a G-Ball image is 170 x 170 pixels – however, images can be resized within HD2 software.

All new G-Ball elements will be created with a ‘red dot’ marker. This can be changed as shown here.

Example images are shown below.

G-Ball Settings

When an element is selected, its settings are shown in the right-hand panel.

Defining the X and Y axes

Although the standard use of g-ball elements is to show lateral and longitudinal acceleration, the X and Y data set to display on the G-Ball can be changed using the two drop-down menus within the axis sections.

The first drop-down menu defines the source. Select either CAN, GPS, Heart rate monitor (if being used with a heart rate element), Maths Channels or OBD.

Note: CAN, Maths Channels and OBD options will only appear if they have been set up by the user.

The second drop-down list defines the channel to be shown. In the example above, GPS Lateral acceleration is set to display in g.

A number of GPS parameters are available to choose from, such as the following:

  • Satellites
  • UTC time
  • Latitude
  • Longitude
  • Speed
  • Heading
  • Height
  • Longitudinal acceleration
  • Lateral acceleration
  • Combined acceleration
  • Vertical speed
  • Local time
  • Day of month
  • Month
  • Year
  • Distance since power-up
  • Distance since stationary
  • Time stationary 
  • Time moving
  • Radius of turn
  • Gradient (%)
  • Solution type

More information on the parameters can be found here.

​Changing the units

Within the parameter section, speed, acceleration or distance channels can be set to display in different units.

The options available are:

  • Speed – km/h, mph, kts, m/s, ft/s
  • Acceleration – g, m/s², ft/s²
  • Distance – m, ft, km, mi, nmi

Setting the G-Ball range

The values set here will define the minimum and maximum values to be shown on the G-Ball element.

The default settings are +/- 2 g in either direction. To test what will be shown on the G-Ball, enter a value into the ‘Test value’ box.



Longitudinal g value = 0 g


Longitudinal g value = 1 g


Longitudinal g value = 2 g


Lateral g value = 0 g


Lateral g value = 1 g


Lateral g value = 2 g

Changing the G-Ball marker

All g-ball elements from the library include a red marker image. This can be changed to a different colour using the drop down as shown below.

Custom user images can be loaded by ticking the ‘user image’ box and then loading a PNG image.

Loading a new G-Ball background

G-Ball images can be changed by clicking the search icon 40.png next to the currently loaded image.

G-Ball backgrounds can be made transparent by ticking the ‘Transparent’ option within the g-ball background area.

Elements and their associated settings can be duplicated within a scene by either right clicking on the element, selecting 'Copy' from the dropdown then right-clicking in an empty area and selecting 'Paste' from the dropdown, or by using keyboard shortcuts 'Ctrl + C' (Copy) and 'Ctrl + V' (Paste).

Elements can be removed from the scene in two ways; either by right-clicking on the element, selecting 'Delete' from the dropdown and confirming the prompt, or by pressing the 'Delete' key on a keyboard, and again, confirming the prompt.
