By default, all geometry in a scene is available for picking. Upon writing applications with interaction possibilities, this is often not what you want. To exclude parts of the scene graph from pick actions, use the SoPickStyle::UNPICKABLE.
You can also optimize pick operations by using the SoPickStyle::BOUNDING_BOX pickstyle.

Constructor. |
|
Destructor. |
|
Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system. Reimplemented from SoNode. |
|
This function performs the typical operation of a node for any action. Reimplemented from SoNode. |
|
Action method for SoCallbackAction. Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph. Reimplemented from SoNode. |
|
Action method for SoPickAction. Does common processing for SoPickAction action instances. Reimplemented from SoNode. |
|
Which strategy to use for the picking actions for subsequent shapes in the scene graph. |
