◆ HandleComplexGestureEvents()

virtual void vtkVRRenderWindowInteractor::HandleComplexGestureEvents ( vtkEventData ed)
virtual

Handle complex gesture events.

Complex gesture events recognition starts when both buttons mapped to the ComplexGesture action are pressed.

To differentiate the Rotate, Pinch and Pan gestures, the default implementation is based on the following heuristic:

  • Pinch is a move to/from the center point.
  • Rotate is a move along the circumference.
  • Pan is a move of the center point.

After computing the distance along each of these axes in meters, the first to break the hard-coded threshold wins.

Overriding both HandleComplexGestureEvents() and RecognizeComplexGesture() allows to define a different heuristic.

GetCurrentGesture(), SetCurrentGesture()

◆ RecognizeComplexGesture()

virtual void vtkVRRenderWindowInteractor::RecognizeComplexGesture ( vtkEventDataDevice3D edata)
virtual

Handle complex gesture events.

Complex gesture events recognition starts when both buttons mapped to the ComplexGesture action are pressed.

To differentiate the Rotate, Pinch and Pan gestures, the default implementation is based on the following heuristic:

  • Pinch is a move to/from the center point.
  • Rotate is a move along the circumference.
  • Pan is a move of the center point.

After computing the distance along each of these axes in meters, the first to break the hard-coded threshold wins.

Overriding both HandleComplexGestureEvents() and RecognizeComplexGesture() allows to define a different heuristic.
