Multiple time scales enable animations over multiple shots. Time-dependent data is specified with reference to time references. Data expressed in different time references may be combined to form animations, shots, and sequences of shots. Time transformations specifying mappings between time references are used to combine data expressed in different time references. Data can be viewed in arbitrary time references. Editing data specifying a sequence of shots may be used as a time reference for viewing data expressed in other time references. Data expressed in one time reference may be rearranged according to another time reference to indicate time reference relationships. Data authored in one time reference may be viewed and modified in another time reference. Modifications are converted from the viewing time reference to the data's original time reference for updating data. Time-dependent data may be expressed in layer data structures. Layer relationships may include time transformations.
