OptiTrack Streaming Engine

Data Streaming pane in Motive

The OptiTrack Streaming Engine allows you to stream tracking data via Motive's free streaming plugins or any custom built NatNet interfaces. To begin streaming, select Broadcast Frame Data. Select which types of data (e.g. markers, rigid bodies, or skeletons) will be streamed, noting that some third party applications will only accept one type of data. Before you begin streaming, ensure that the network type and interface are consistent with the network you will be streaming over and the settings in the client application.

Broadcast Frame Data

(Default: False) Enables/disables broadcasting, or live-streaming, of the frame data. This box must be checked in order to start the streaming.

Local Interface

(Default: loopback) Sets the network address which the captured data is streamed to. When set to local loopback (127.0.0.1) address, the data is streamed locally within the computer. When set to a specific network IP address under the dropdown menu, the data is streamed over the network and other computers that are on the same network can receive the data.

Labeled Markers

(Default: True) Enables/disables, streaming of labeled Marker data in the frame. The markers are either point cloud solved or model filled.

Unlabeled Markers

(Default: True) Enables/disables streaming of all of the unlabeled Marker data in the frame. The markers are either point cloud solved or model filled.

(CHECK) Solver Replaces Occlusion

(Default: True) Enables/disables streaming of named collections of identified markers and their positions (X, Y, Z). In other words, this includes markers that are associated with any of the assets (MarkerSet, Rigid Body, Skeleton). The streamed list also contains a special marker set named all which is a list of labeled markers in all of the assets in aTake

Rigid Bodies

(Default: True) Enables/disables streaming of rigid body data, which includes the name of rigid body assets as well as positions and orientations of their pivot points.

Rigid Body Model Markers

(Default: True) Enables/disables streaming of Model Markers which represent the expected marker positions of rigid body assets in the scene.

Skeletons

(Default: Skeletons) Enables/disables streaming of skeleton assets, if present.

Skeleton Coordinates

(Default: Global) When set to Global, the tracking data will be represented according to the global coordinate system. When this is set to Local, the streamed tracking data (position and rotation) of each skeletal bone will be relative to its parent bones.

Skeleton as Rigid Bodies

(Default: False) When set to true, skeleton assets are streamed as a series of rigid bodies that represent each skeleton segment.

Bone Naming Convention

(Default: Motive) Determines the bone naming convention of the streamed data among Motive, FBX, and BVH. The naming convention must match with the format used in the streaming destination.

Up Axis

(Default: Y Axis) Selects the upward axis of the right-hand coordinate system in the streamed data. When streaming onto an external platform with a Z-up right-handed coordinate system (e.g. biomechanics applications) change this to Z Up.

Remote Trigger

(Default: False) Allows using the remote trigger for the streaming.

Type

(Default: Multicast) Selects the mode of broadcast for NatNet. Valid options are: Multicast, Unicast.

Stream Subject Prefix

[Advanced] (Default: True) When set to true, each marker label includes a subject prefix, which is the name of associated asset.

Stream Visual3D Compatible

[Advanced] Enables streaming to Visual3D. Normal streaming is not compatible with Visual3D, and this feature must be enabled in order to stream tracking data to Visual3D.

Scale

[Advanced] Sets the scaling for streamed skeletal data.

Command Port

[Advanced] (Default: 1510) Specifies the port to be used for negotiating the connection between the NatNet server and client.

Data Port

[Advanced] (Default: 1511) Specifies the port to be used for streaming data from the NatNet server to the client(s).

Multicast interface

[Advanced] Specifies the multicast broadcast address. (Default: 239.255.42.99). Note: When streaming to clients based on NatNet 2.0 or below, the default multicast address should be changed to 224.0.0.1 and the data port should be changed to 1001.

VRPN Streaming Engine

(Default: False) Streams rigid body data via the VRPN protocol.
