public class SoInteractiveSwitch extends SoSwitch
SoSwitchnode for its inherited
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
SoDragger), for example dragging a slice through a volume data set.
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
whichInteractiveChild field, and when interaction is stopped, the standard
whichChild field value will again be used as the index to traverse.
SoGroup, NOT an
SoSeparator, and therefore does not provide render caching. Generally if the children contain geometry, it is good practice to make each child an
SoSeparatorto make render caching more effective.
SoSwitch. While interacting, traverses the chosen (from
whichInteractiveChild) child or children. Sets:
SoInteractiveSwitchElement. While not interacting, traverses the chosen (from
whichChild) child or children. Sets:
