(Inherited from SoDisposable.) | |
UserData |
Gets or sets the user data to be contained by the field container.
(Inherited from SoFieldContainer.) | |
whichChild | Index of the child to traverse, or one of SO_SWITCH_NONE, SO_SWITCH_INHERIT, or SO_SWITCH_ALL. | |
whichInteractiveChild | Index of the child to traverse during interaction, (or one of SO_SWITCH_NONE, SO_SWITCH_INHERIT, or SO_SWITCH_ALL). |
This group node has the same base behavior as the OIV.Inventor.Nodes.SoSwitch node for its inherited whichChild field.
It has the additional feature of (optionally) traversing a different (or no) child during an "interaction". This allows the application to provide higher performance during an interaction by switching to a less complex version of a geomtry or not rendering the geometry at all. Interaction includes moving the camera (navigating around the scene) and interacting with a dragger (see OIV.Inventor.Draggers.SoDragger), for example dragging a slice through a volume data set.
The OIV.Inventor.Nodes.SoInteractiveSwitch.whichInteractiveChild field specifies the index of the child to traverse (where the first child has index 0), when a user interaction, for example moving the camera, is in progress. This means that while the camera is moving, the traversed children will be the children defined by the OIV.Inventor.Nodes.SoInteractiveSwitch.whichInteractiveChild field, and when interaction is stopped, the standard OIV.Inventor.Nodes.SoSwitchwhichChild field value will again be used as the index to traverse.
NOTES:
Remember that the default value for both whichChild and whichInteractiveChild is SO_SWITCH_NONE, meaning that nothing is displayed by default.
Remember that this node is an OIV.Inventor.Nodes.SoGroup, NOT an OIV.Inventor.Nodes.SoSeparator, and therefore does not provide render caching. Generally if the children contain geometry, it is good practice to make each child an OIV.Inventor.Nodes.SoSeparator to make render caching more effective.
InteractiveSwitch {
whichChild | -1 |
whichInteractiveChild | -1 |
inherited from OIV.Inventor.Nodes.SoSwitch. While interacting, traverses the chosen (from OIV.Inventor.Nodes.SoInteractiveSwitch.whichInteractiveChild) child or children. Sets: OIV.Inventor.Elements.SoInteractiveSwitchElement. While not interacting, traverses the chosen (from whichChild) child or children. Sets: OIV.Inventor.Elements.SoSwitchElement.
