Class Time_Curve is the simplest subclass of Time_Object. It is designed for working with time-dependent curves, in contrast to Time_Object it uses a specific data structure: the geometry Chain has a TimeStep sequence as object, the objects of the TimeSteps are of class Triang1d. There are only a few methods on Time_Curve, most functionality -- even the user-interface -- is inherited from the superclass.
The structures and methods for Time_Curve are defined in the Curve project described in section 8.2.2, therefore the typedefs for TIME_CURVE and CURVE_PARM are not part of the grape.h header file (you shouldn't need them anyway). All sources for this project can be found in demo directory.
