// Description : A base class for nodes that may choose to render only

// some subset of their children, based on some internal
|
|
// criteria.
|
|
//
|
|
// This is an abstract base class, and is only

|
// interface; it is defined in this directory so that
|
|
// FrustumCullTraverser can access it. All of the
|
|
// implementations of this class are defined in the
|
|
// switchnode directory.
