public class SoVRMLSwitch extends SoVRMLParent
NOTE: This field is not compatible with VRML97. If you specify a non-default value for this field, when this node is written to a VRML file, the file will contain this incompatible field and standard VRML97 file readers will not be able to read it. See the VRML97 Specification, below.
This section describes the expected behavior of the node in a conforming VRML97 browser application. In some cases, the application is responsible for implementing portions of the expected behavior. Open Inventor viewer classes and IVF classes implement some of the application behaviors.
This section may reference portions of the VRML97 specification that are not present in this help file. The complete VRML97 spec is available at
The SoVRMLSwitch grouping node traverses zero or one of the nodes specified in the choice field.
See the "Concepts - Grouping and Children Nodes" section which describes "children nodes" for a details on the types of nodes that are legal values for choice.
The whichChoice field specifies the index of the child to traverse, where the first child has index 0. If whichChoice is less than zero or greater than the number of nodes in the choice field then nothing is chosen.
SoSwitch node or from certain other nodes (such as SoArray or SoMultipleCopy) that set the switch value.
SoGroup.
The bboxCenter and bboxSize fields specify a bounding box that encloses the SoVRMLSwitch's children. This is a hint that may be used for optimization purposes. If the specified bounding box is smaller than the actual bounding box of the children at any time, then the results are undefined. A default bboxSize value, (-1 -1 -1), implies that the bounding box is not specified and if needed must be calculated by the browser. See "Concepts -
Bounding Boxes" for a description of the bboxCenter and bboxSize fields.
Note that all nodes under an SoVRMLSwitch continue to receive and send events regardless of the value of whichChoice.
