Detailed Description

Base class for all group nodes.

This node defines the base class for all group 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 (SoGroup does not push or pop traversal state as SoSeparator does).

FILE FORMAT/DEFAULT

    Group {
    }
