The Curve project is used to compute explicitly given time-dependent curves, the class Time_Curve it is based on is the simplest subclass of Time_Object, see section 7.4.2.
The user-interface is inherited from the Time-Object project, the extended functionality is added by replacing the methods for reading the description files, allocating memory for the geometry and computing the data.
Additional to the Time-Object data for task, frame and parameter the Curve description files with extension *.cv contain information about the definition interval and the explicit formulas for the curve, see the example in section 8.2.2.2.
