A Group node contains children nodes without introducing a new transformation\&. It is equivalent to a Transform node containing an identity transform\&. More details on the children, addChildren, and removeChildren fields and eventIns can be found in 4\&.6\&.5, Grouping and children nodes (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.5)\&.

.PP
The bboxCenter and bboxSize fields specify a bounding box that encloses the Group node's children\&. This is a hint that may be used for optimization purposes\&. The results are undefined if the specified bounding box is smaller than the actual bounding box of the children at any time\&. A default bboxSize value, (-1, -1, -1), implies that the bounding box is not specified and, if needed, is calculated by the browser\&. A description of the bboxCenter and bboxSize fields is contained in 4\&.6\&.4, Bounding boxes (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.4)\&.
