// Class : EggBackPointer
|
|
// Description : This stores a pointer from an EggJointData or
|
|
// EggSliderData object back to the referencing data in
|
|
// an egg file. One of these objects corresponds to
|
|
// each model appearing in an egg file, and may
|
|
// reference either a single node, or a table, or a slew
|
|
// of vertices and primitives, depending on the type of
|
|
// data stored.
|
|
//
|
|
// This is just an abstract base class. The actual
|
|
// details are stored in the various subclasses.
