You specify system-wide settings in the System Resources pane, by clicking on the top-level node called Local Vicon System. This node is displayed when Nexus is in Live mode (if necessary, click the Go Live button to see this node). It contains sub-nodes for each device connected to your Vicon system.
If you have saved any system configurations (.system files), before changing Local Vicon System settings, ensure the required configuration is selected at the top of the System Resources pane (see Manage configurations in Vicon Nexus).
The Local Vicon System node provides access to system-wide properties, enabling you to:
- Configure the Vicon system capture rate and the amount of memory allocated to Nexus for motion capture.
- Manage the way Nexus produces real-time 3D representations of the subjects whose motion is being captured.
- Specify the identification and connection settings for the Nexus host PC.
- Specify video standards and timecode options.
To change Vicon system settings:
- If Nexus is currently offline, in the Resources pane, click Go Live.
- On the System tab, click the Local Vicon System node.
In the Properties pane at the bottom of the System tab, view or change the settings to suit the needs of your motion capture application.
When you set up your Vicon system, ensure that the Requested Frame Rate value in the System section is appropriate.
The Requested Frame Rate is the rate (in Hz) at which to synchronize the Vicon cameras. Depending on whether you use an external video signal, select the required setting:
If you don't use an external video signal (and therefore haven't set the Genlock Standard (an Advanced property: see Step a. below), the default setting of 100 Hz is suitable for a range of common applications, so unless you have a specific requirement for a different value, don't change it.
If you use an external video signal:
To view all the available properties for Local Vicon System, at the top right of the Properties pane, click Show Advanced.
From the Genlock Standard list (an Advanced property), ensure the correct video standard (PAL, NTSC, Film, VESA, SDI, etc) is specified.
From the Requested Frame Rate list, select one of the displayed values (multiples of the base frame rate, up to a maximum of 2,000).
Configure additional properties as required. For detailed information about each of the properties, see Local Vicon System properties in the Vicon Nexus Reference Guide.
When you have finished specifying the properties, at the top of the System tab, click the Save button to save your system configuration settings to a .system file in the Systems configurations folder (see Manage configurations in Vicon Nexus).
