// Description : This represents the set of clip planes and/or
|
|
// occluders that are definitely in effect for the
|
|
// current node of the CullTraverserData, as well as on
|
|
// all child nodes. Any clip planes and occluders in
|
|
// this list may be safely culled against.
|
|
//
|
|
// This does not include the clip planes that are in
|
|
// effect now, but might later be turned off by a child
|
|
// node, since we can't safely cull against such clip
|
|
// planes.
|
|
//
|
|
// The bounding volumes in this object are transformed
|
|
// for each level of the scene graph.
