- All Implemented Interfaces:
public class SoInteractiveSwitch extends SoSwitchGroup node that traverses one chosen child depending on scene interaction. This group node has the same base behavior as the
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.
whichInteractiveChildfield 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
whichInteractiveChildfield, and when interaction is stopped, the standard
whichChildfield value will again be used as the index to traverse.
- 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
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.
