// Class : PreparedGraphicsObjects
|
|
// Description : A table of objects that are saved within the graphics
|
|
// context for reference by handle later. Generally,
|
|
// this represents things like OpenGL texture objects or
|
|
// display lists (or their equivalent on other
|
|
// platforms).
|
|
//
|
|
// This object simply records the pointers to the
|
|
// context objects created by the individual GSG's;
|
|
// these context objects will contain enough information
|
|
// to reference or release the actual object stored
|
|
// within the graphics context.
|
|
//
|
|
// These tables may potentially be shared between
|
|
// related graphics contexts, hence their storage here
|
|
// in a separate object rather than as a part of the
|
|
// GraphicsStateGuardian.
