To add a Tracker tool to the dependency graph:
➤ Do one of the following:
■ From the Tools tab, drag the Tracker tool to Schematic.
■ From the Tools tab, open the Tracker folder and drag the Tracker
Analyzer tool to Schematic. You do not need to attach it directly to
the dependency graph but rather to the image sequence you want to
analyze as it is not going to be modifying the image but rather you
will be using data associated with that tracker.
Unlike the Tracker Analyzer, the Tracker lets you add multiple Tracker
Analyzer tools. If you added the Tracker tool and you want to add more
than one Tracker Analyzer, click Add in the File Browser.
You can also add Trackers and Tracker Analyzers to a dependency graph using
the Create Trackers feature found in any tools with position, rotation, scale,
and pivot parameter controls. These tools include the Panner, 2D Transform,
Reaction, Warp 2D, Garbage Mask, and Remove Dust. Furthermore, shape
tools (Warp 2D, Garbage Mask, and Remove Dust) also let you create Trackers
on a per point basis.
The Create Trackers toggle button is found in the Tracker Selection Dialog. It
only applies if you are going to press the Link button. Ordinarily the Tracker
Selector Dialog allows you to select a set of 1 or more tracker analyzers to link
or copy to. However, if Create Trackers is selected, then when you press Link,
it will actually create the required number of tracker analyzers. Where it creates
them depends on whether you have a tracker tool selected or not. If one is
selected, it creates the new analyzers in that tool, otherwise, it creates a new
tracker tool, with the required number of analyzers. In the following example
procedure, the 2D Transform tool is used to create the Tracker and required
number of tracker analyzers specified by the Transform Type selected.
