.PP 
The \fBSoPickStyle\fP class is a node for setting up how to do picking\&. 

By default, all geometry in a scene is available for picking\&. Upon writing applications with interaction possibilities, this is often \fInot\fP what you want\&. To exclude parts of the scene graph from pick actions, use the \fBSoPickStyle::UNPICKABLE\fP\&.

.PP
You can also optimize pick operations by using the \fBSoPickStyle::BOUNDING_BOX\fP pick style\&.

The behaviour of this setting will also depend on the SoShapeStyle vertexOrdering and shapeType setting, which are used to flip front faces to become back faces and vice versa and to turn backface culling on and off\&.
