Figure 1-1 Cube Scene Graph
The csGroup Class
The csGroup class allows applications to group a list of csNodes. When the application
then applies actions to the csGroup, the actions traverse the scene graph starting at the
group-type node. The group-type node passes the action to some or all of its children.
The bounding sphere of a csGroup is the bounding sphere containing all the bounding
spheres of its children.
In Figure 1-1, a group node is the top of the scene graph, joining two csTransform nodes
and a light.
