Detailed Description
The picking settings determine how the entity picking is handled. For more details about entity picking, see Qt3D.Render::ObjectPicker or Qt3D.Render::RayCaster component documentation.
When using ObjectPicker components, picking is triggered by mouse events.
When using RayCaster or ScreenRayCaster components, picking can be explicitly triggered by the application.
In both cases, a ray will be cast through the scene to find geometry intersecting the ray.
See also ObjectPicker, RayCaster, and ScreenRayCaster.
