keep tracking tight on the Trackable.
The prediction algorithm available are:
None: No prediction is used.
Note: When the Following Sensitivity is set to None or Multiple, the Ahead Time and Delay
Time settings and options are not displayed.
Standard Prediction: Taking the pan and tilt settings of fixtures following the Trackable, a Kalman
filter is used to estimate the velocity and poisition of the fixture. A prediction of the fixture's future
pan/tilt values is then created.
Delay: Fixtures will follow a Trackable’s position after a set amount of time. This causes fixtures to
follow behind moving Trackables. Useful for effects.
Linear Prediction: Taking the current BTBeacon position as input, a Kalman filter is used to estimate
the velocity, and position of the Trackable. A prediction of the Trackable’s future movement is then
created.
Second Order Prediction: Taking the current BTBeacon position as input, a Kalman filter is used to
estimate the acceleration, velocity, and position of the Trackable. A prediction of the Trackable’s
future movement is then created.
Second Order+Prediction: Taking the pan and tilt settings of fixtures following the Trackable, a
Kalman filter is used to estimate the acceleration, velocity, and position of the fixture. A prediction
of the fixture’s future pan/tilt values is then created.
Fixture responsiveness can also be configured with prediction. Fixture responsiveness is measured on a
scale of -4 (Smooth) to 2 (Responsive).
Smooth: A fixture set to smooth will follow Trackables in a fluid manner. This may appear as a
delay in extreme cases.
Responsive: A fixture set to responsive will jump to and track every slight movement of a
Trackable. This may appear very jumpy in extreme cases.
Note: It is recommended that you test a fixture’s prediction prior to use, to determine if the chosen
prediction movement is right for your tracking needs.
To assign an algorithm to a fixture
In the Chapter widget, select the chapter the fixture is in.1.
In the Center pane, click on the Trackable the fixture is assigned to and click on the Fixture Icon of2.
the fixture to select it.
With the Fixture Icon selected, go to the Fixture Settings widget.3.
Under the Basic Settings section, select the desired sensitivity from the Sensitivity drop-down4.
menu.
If you want the fixture to be tracking ahead of where the Trackable will be, enter how far
ahead in time (milliseconds) in the Ahead Time field.
Assign how reactive you want the fixture to follow by adjusting the Turner value slider to between5.
Smooth or Responsive.
