8.0
This plug-in provides support for the Xsens MVN motion capture device. The Moven plug-in supports both position and rotation data.
The Moven plug-in is implemented as a Vizard extension. When creating the Moven extension, you must specify the IP address or hostname of the MVN Studio server as the 'mesg' argument. You can also specify the port number by adding a ':' followed by the port number to the address string. The default port is 9763.
To receive 6DOF data, make sure MVN Studio is setup to stream either Euler or Quaternion based orientations. 3DOF marker data is only provided if MVN Studio is setup to stream position only.
The Moven extension object has the following methods/constants:
|
Method |
Description |
| <moven>.getAvatarList() | Returns a list of all Moven avatars on the server. |
|
<moven>.getBody(id) |
Returns the body sensor with the specified Moven body ID belonging to the first avatar. See below for available body IDs. |
|
<moven>.getMarkerList() |
Returns a list of all the 3DOF markers on the server belonging to the first avatar. |
|
<moven>.getBodyList() |
Returns a list of all the 6DOF bodies on the server belonging to the first avatar. |
|
<moven>.getMarker(id) |
Returns the marker sensor with either the specified Moven marker ID or tuple containing the Moven body ID and local marker ID belonging to the first avatar.. |
|
<moven>.getBodyMarkers(id) |
Returns a list of marker sensors that belong to the specified Moven body ID. See below for available body IDs. |

The following example shows how to connect to a MVN studio server and get a handle to the 6DOF head sensor:
The following example shows how to iterate through all the marker objects and link each one to a node:
You can also connect to multiple MVN Studio servers simultaneously. The next example connects to two different servers and gets a handle to the right hand of each server:
