Remarks

This node defines the base class for all group nodes. OIV.Inventor.Nodes.SoGroup is a node that contains an ordered list of child nodes. The ordering of the child nodes represents the traversal order for all operations (for example, rendering, picking, and so on). This node is simply a container for the child nodes and does not alter the traversal state in any way. During traversal, state accumulated for a child is passed on to each successive child and then to the parents of the group (OIV.Inventor.Nodes.SoGroup does not push or pop traversal state as OIV.Inventor.Nodes.SoSeparator does).

FILE FORMAT/DEFAULT

Group { }

ACTION BEHAVIOR

OIV.Inventor.Actions.SoGLRenderAction, OIV.Inventor.Actions.SoCallbackAction, OIV.Inventor.Actions.SoGetBoundingBoxAction, OIV.Inventor.Actions.SoHandleEventAction, OIV.Inventor.Actions.SoRayPickAction Traverses each child in order.

OIV.Inventor.Actions.SoGetMatrixAction Does nothing unless the group is in the middle of the path chain the action is being applied to. If so, the children up to and including the next node in the chain are traversed.

OIV.Inventor.Actions.SoSearchAction If searching for group nodes, compares with this group. Otherwise, continues to search children.

OIV.Inventor.Actions.SoWriteAction Writes out the group node. This method also deals with any field data associated with the group node. As a result, this method is used for most subclasses of OIV.Inventor.Nodes.SoGroup as well.
