A system and method that manages scene graphs by data staging is contemplated.
Data staging entails selectively loading only the portions of the scene graph that
are currently needed or likely to be needed in the near future. Other objects in
the scene graph that are not currently needed or likely to be needed may be replaced
by pointers. The pointers may point to the location from which the objects may
be accessed if necessary for a future frame. The replaced portions of the scene
graph may be compressed and/or cached to a local memory device (e.g., a local array
of read-write optical drives) capable of storing large amounts of data, with the
pointers indicating where the objects are stored.
