Pixera Tracking modules

 

Licensing

Most tracking modules require a Pixera Enterprise license.The exceptions:
The SPNet, Psn and FreeD modules are available in all Control licenses. If no Enterprise license is found, all other tracking modules will be available in a demo mode. That means that the modules can be used, but the Tracking information is blocked after 15 minutes. After that a new activation of the init action inside the module is required.


Basics

All tracking modules are built in the same way. This means that the workflow of each module is almost the same.
 
 The basic workflow:

  1. Add the module to the Pixera Control workspace
  2. Modify the Properties of the module
  3. Init the module
  4. Select the UI of the Module
  5. Click Start learning
  6. Wait until the Tracking object are found
  7. Click Update actions form learned data
  8. Save the Project
  9. Connect the Tracking actions to the Pixera API
     
     

Adding the module

Drag the module form Library to the workspace
In this example we use the SPNet module for Stage Precision is located in Drivers -> StagePrecision -> SPNet


Modifying the properties

Select the properties tab in the inspector after selecting the module.

 

Depending on the Tracking module there are different properties. The properties have default values, but they may need to be modified.

  • Multicast Ip: if the tracking Protocol is using multicast, the address can be set here.
  • Port: The local UDP port where the packets are received.
  • Adapter IP: Local network adapter where the tracking packets are expected
  • Expected Frequency
  • Damping
  • Auto Init: Needs to be enabled


 Initialize the module

If Auto Init is enabled this can be skipped, otherwise the init() action of the module has to be executed. The IsOpen slot will be set to true:







The learning function of the tracking configuration

Select the module and switch to the UI tab of the inspector.


Inside this UI it is possible to discover the tracking objects and generate the required actions.

After pressing the “Start Learning” button the indicator will change to green and the module starts collection tracking objects. The collected Objects are listed. It is important, that the tracking system is sending all objects. For example, if the sender is set to send on change only and the object is not moving no data is sent, and the objects are not found.

Stop Learning stops the collection of the tracking data. 

Reset Learned data cleans the collected data, to start from the beginning.


When all available tracking objects are found the button “Update Actions from Learned Data” must be selected. The actions of the module gets updated with the available moving objects, and the module is reinitialized if Auto Init is set. Otherwise, the init action must be triggered manually. The new actions are named depending on type and ID/ name. After that the UI tab is not required anymore and can be empty. 

Save the project.

 

Depending on the Tracking module the names of the tracking objects can vary, but the main structure is always the same. For this example Stage Precision is providing two objects. A Movable with the name DemoMovable and a Camera mit the name DemoCamera. Depending on the type different actions are generated.

Warning

When tracking with the Direct API is used, no studio camera position and settings can be manually set anymore.
To be able to set it again, you have to disable the tracking modules with uninit().


 


This action needs to be connected to a corresponding action of the Pixera module. The tracking values are only visible after the connection is placed established.
