Detailed Description
Controller button press and release event.
SoControllerButtonEvent represents controller button press and release events in the Open Inventor event model. A controller device generally has associated 3D tracker information.
A "tracker" is any device whose position and orientation are dynamically tracked in 3D, typically for immersive VR applications. For example: a head tracker. A "controller" is an input device which typically has buttons and/or valuators (e.g. a joystick). Many controllers have an associated tracker. For example, the commonly used "wand" input device has three buttons, a two-axis joystick (two valuators), and an associated tracker.
The virtual method SoEvent::getTrackerInfo() can be used to determine if an event object has associated tracker information. Traditional 2D events like SoMouseButtonEvent and SoLocation2Event return NULL. 3D events like SoTrackerEvent and SoControllerButtonEvent return a their associated tracker information (SbTrackerInfo).
Many controller devices generate a continuous stream of data, so strictly speaking there are no "events". However Open Inventor classes that recognize the SoControllerButtonEvent interpret it as notification of a change in the button state (press or release). The application (or other software above Open Inventor) is responsible for deciding when to actually create an SoControllerButtonEvent.
