Tracking Systems

The Tracking System panel represents the tracking software in the studio.

Click on a tracking system icon to view its properties (see Parameter Panel).

A line from the tracking system represents a connection to a Rig.

Right-click Menu:

• Connect to: Connects to a Rig.

• Connect/Disconnect: Connects to or disconnects from the tracking system.

• Analyze timing: See Analyze Time.

• Analyze rawdata: Enables or disables the collection of raw data for analytical purposes.

• Delete: Removes the Tracking System.
  Right-click on a Bar:

• Reset bar’s min/max: Resets the minimum and maximum value of each bar.

• Reset spectrum’s min/max: Resets the minimum and maximum value of the whole spectrum and each bar.

Rigs

A Rig is the interface between the Tracking System and the Viz Engine. Click on any Rig icon to view its properties (see Parameter Panel).

A line from a Rig on the left represents a connection to a tracking system (see Tracking Systems). A line from a Rig on the right represents a connection to a Service (see Services).

Rigs are defined as the following types:

• Translation

• Arm

• Location Pivot Rotation

• Pivot Rotation

• Camera

• Object
  The Translantion rig is for position data only, and provides the Tracking Hub with the following parameters:

• pos_x

• pos_y

• pos_z
  The Arm rig can be rotated in 3 dimensions, and starts with a swivel. It has a defined length with a defined direction, and offsets between swivel and length.

Both the Translation and Arm rigs are used for camera systems such as Spidercam:

The Location Pivot Rotation rig is a rotation interface in the X-Z dimension, with center point (0/0).

Pivot Rotation is a rotation rig with a definable center point. The rig provides the Tracking Hub with the following coordinates:

• pivotx

• pivoty

• pivotz
  Camera is a basic rig for tracked cameras.

Object is a basic object for tracked objects.

Services

A Service is the element of a Viz Engine which is connected to the Tracking System through the Rig.

Click on a Service icon to view its properties (see Parameter Panel).

A line from the a Service represents a connection to a Rig (see Rigs).

Services available are:

• Camera: Tracks a camera for Viz Engine .

• Object: Tracks an object with Viz Engine.

• Parameter: Provides all required data for the creation of the 3d View.

• MoCap: Captures motion for Viz Engine.

• Communication Timing: Sends timing information which are measured during tracking data acquisition.

• Tracking Timing: Sends timing information which are measured during sending the data as service to the engines.
  Right-click displayed object for additional menu:

• Analyze timing: See Analyze Time

Topology Connection Lines

The Topology Connection Lines show the connections between each item in the Topology. Double-clicking a Topology connection line between a Tracking System and a Rig opens the Tracking parameter routing window for the connection:

Topology Colors

The colors of the icons in the Topology view show the working condition:

• Green: Everything is OK and in regular working condition.

• Grey: The tracker is not connected or deactivated.

• Orange: The Service or Tracker state is in warning condition. See the log or message for more information.

• Red: The Tracker or Service is in a serious error state. See log or message for more information.

Motion Capturing with Motion Analysis

Motion Capturing is a special way of collecting and forwarding data to an engine.
There are no camera positions transmitted, but the movements of a person.

For these special procedures, there's a new rig and a new service available.

Selectable via the menu:
Rigs --> Add MoCap
Services --> Add mocap service

Connect the MA Tracking System to the MoCap Rig as usual.

In this case, there is just one axis available.

Name of the axis is depending on the used name in MA's Cortex.

Mocap Service can be used as other services.
