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.

  • 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.

images/download/attachments/41794790/image2018-7-3_13-24-17.png

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

Mocap Service can be used as other services.
