Detailed Description
When QPickingSettings::pickMode() is set to QPickingSettings::TrianglePicking, the signals on QObjectPicker will carry an instance of QPickTriangleEvent.
This contains the details of the triangle that was picked.
Note: In the case of indexed rendering, the point indices are relative to the array of coordinates, not the array of indices.
See also QPickingSettings, QPickEvent, QObjectPicker, and QAttribute.
