| Import Statement: | import Qt3D.Render 2.14 |
| Since: | Qt 5.7 |
| Instantiates: | QPickingSettings |
Properties
- faceOrientationPickingMode : enumeration
- pickMethod : enumeration
- pickResultMode : enumeration
- worldSpaceTolerance : qreal
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.
