// Class : CullBin
|
|
// Description : A collection of Geoms and their associated state, for
|
|
// a particular scene. The cull traversal (and the
|
|
// BinCullHandler) assigns Geoms to bins as it comes
|
|
// across them.
|
|
//
|
|
// This is an abstract base class; derived classes like
|
|
// CullBinStateSorted and CullBinBackToFront provide the
|
|
// actual implementation.
