Figure 42 above shows the Network Streaming preferences. The table below summarizes the
functionality of each selection. Please refer to the Real-Time Network Streaming Protocol Specification
for further details.
Datagram
Description
Position + Orientation
(Quaternion)
Positions and orientation of each body segment, orientations in
quaternion format, position units are in meters. This is the most accurate
and preferred format for new application development. Use this to stream
from one MVN Studio to another. Select the ‘Scaling Data’ for proper
visualization of the character mesh.
Position + Orientation
(Euler)
Position and orientation of each body segment. Orientations are Euler
and position data is in meters. This is the format needed to send data to
the MVN MotionBuilder Live plug-in. See the MVN MotionBuilder plug-in
user manual for further details.
Avatar Meta Data
Particularly useful when streaming data during multi-person capture,
when selected, this protocol streams information inserted about the
character including the character as inserted in the Navigator as well as
the ID of the Body Pack or Awinda Station.
This feature is supported by MVN Studio as a network monitor.
Avatar Scaling data
This packet contains scaling information about the character, including
the null pose definition and point definitions to scale a mesh.
Unity 3D
This setting should be selected in the network streamer for users of the
Unity plugin. See the Unity plugin user manual for more details.
Siemens Tecnomatix
For MVN BIOMECH customers, it is possible to stream data in real-time
to Siemens PLM software using this selection. See separate user manual
for set up.
Linear Segment
Kinematics
Absolute segment position, linear velocity and linear acceleration.
Angular Segment
Kinematics
Absolute segment orientation, angular velocity and angular acceleration.
Virtual Optical Marker Set
This protocol streams a set of virtual optical markers. This is the virtual
marker set for the 1.0 Motion Builder plug-in. This data is not supported
for playback in MVN Studio.
Center of Mass
Absolute 3D position of the center of mass.
Tracker Kinematics
Absolute 3D tracker orientation (quaternions) and free acceleration. Local
acceleration, angular velocity and magnetic field of the sensor
components.
This feature is not supported by MVN Studio as a network monitor.
Joint Angles
Data is contains point ID of the parent and child segment orientation and
the joint angle in X,Y,Z.
Time Code
MVN Studio contains a clock which starts running at the start of a
recording. The clock measures the elapsed time in milliseconds. When
data is sampled, the current value of the clock is also sampled and stored
in the datagram(s) as a 32-bit unsigned integer value representing a time
code. When this option is selected a string of this Time Code is streamed
(HH:MM:SS.mmm).
