Position Constraint
Tip:
This tag only works after 3D features have been generated, i.e., a 3D reconstruction has taken place.
This tag only works after 3D features have been generated, i.e., a 3D reconstruction has taken place.
The Position Constraint binds the world origin, for example, to a specific feature (this will be the Object Tracker’s origin if the Object Tracker is used) - the vertex cluster will be positioned accordingly.
Use the tag as follows to calibrate (2 methods):
- Create the tag for the respective Motion Tracker or Object Tracker object. A small orange circle will be displayed at the center of the Viewport (always visible when the tag is active). Drag this circle onto the desired Track or feature:
- Select the Create Position Constraint command (main menu:
and click on the desired Track. A Position Constraint tag with a linked Null object that matches the Track will be created automatically.
The Motion Tracker links the associated Null object in the tag and uses it to define the world origin, for example, by moving the vertex cluster, including the camera, accordingly.
This command creates a Position Constraint tag with a matching linked feature (see previous paragraph).
