Tracker

The tracker can take the form of rigid bodies or points. These objects can be controlled by or output positional data as well as acting as measuring points or triggers.

Coordinates

Name	Description
Position	This will move the object along X, Y and Z axis in the local space.
Scale	Scale of the coordinate system. To scale the Object check the settings under “Display”
Rotation	Rotation of the object along X, Y and Z axis.
Velocity	This is the speed of the object in the direction it is traveling along the X, Y and Z axis.
Acceleration	This is the rate of change of the velocity of the object.

Name	Description
Tracked State	Undefined – When tracker does not have a map input. Inactive – The tracker is not receiving data from the input map. Active – The tracker is receiving positional data from the input map.
Type	Tracker – A point or shape within 3D space which can be used to output positional data of itself or other objects it is assigned to. Rigid Body – A 3D body which moves under physics, this can also be tracked within the 3D space. Measurement Point – This is a tracked start or endpoint which can be used to make a measurement.

Userdata

Display

Name	Description
Display Object	If ticked, the object will be visible in the scene. If un-ticked, the object will not be visible.
Display Label	When on, there will be a label displayed next to the object.
Locked	When un-ticked, it activates keyboard shortcuts – pressing ‘E’ allows you to move and ‘R’ rotate.
Object Colour	Double click the colour block and this will open a colour picker. This can be used to change the object display colour.
Viewport Scale	Dimensions of the object in the viewport in meters.
Display Trace	The trace is a trail that follows the tracker and shows the direction of movement. When un-ticked there will be no trace.
Trace Time	This determines how long the trace is displayed before it disappears.
Trace Colour	Clicking the colour box opens a colour picker with RGB (red, green, blue) and alpha control.
Display	This allows you to change the shape of the tracker – choosing between a cube, sphere or crosshair.
Radius	Distance from the center of the object to the edge of the circle in meters.
Display SubPoints	By turning this on the subpoints of the object will be displayed. When turned off only the main point of the object will be visible.

Filters

Specific Tracker Filters

Prediction Filter

Name	Description
Weight	This is the amount this filter effects the object.
Prediction Time	This is the amount the data will be predicted to help smooth the movement of the object.
Cyclic	The filter will use reoccurring movements to help predict the movement of the object.
Use Position	When ticked the filter will affect the position of the object.
Use Rotation	When ticked the filter will affect the rotation of the object.

Output Mapping

Node Based

The object can be controlled and used as a node. The node is created by clicking and dragging the parameter on to the board.

Name	Description
Type	Input – The nodes input values are determined by incoming values from an external source. Output – The node is outputting data to another source.
Target Object	This is the object that will either be affected by the incoming values or output information.
Position	The directional XYZ values will be displayed here.
Rotation	The rotational XYZ values will be displayed here.
Enabled	When on, the parameter is active and enabled.
Display Colour	This colour block can be changed by changing the parameter.
Tracked Status	This indicates whether the status is Active, Undefined or Inactive, with the values -1, 0 and 1. 1 indicating that the tracking status is active.
Tracked Age

Layout

Name	Description
Editable	When on, the node is editable.
Locked	When on, the node is locked into its position on the board.
