Blacktrax Tracked Body
Updated: 4 Dec 2023
Generates a tracked point from Blacktrax.
Blacktrax Tracked Body
Method #
Takes a single Blacktrax Trackable and provides it as a tracked point (a bit like Null). You can track either the rigid body position and rotation of a given trackable or just individual tracked LEDs. To use, parent other objects to this node to have the positions and rotations inherited.
To enable listening to the Blacktrax data, you need to configure the Blacktrax options in menu: Devices->Mocap/Camera/Streaming Device Settings
A trackable is a Blacktrax name for a tracked object. It can either be a point, or rigid body.
Parameters
These properties control the core behaviours of the node.
Parameter Details Select Trackable
When receiving Blacktrax data, this enables you to select a provided trackable.
Trackable Name
The name of the trackable (as defined by Blacktrax)
Trackable Type
Choose whether to take the centroid of all the LEDs or take the position of a single LED
LED Index
If Trackable Type is LED Points then, choose the index of the LED to track.
Flip Z Axis
Flip positions in the Z axis
Flip Z Rotation
Flip rotations in the Z axis
Inputs
These properties control the core behaviours of the node.
