A computer-implemented method of configuring animation of a virtual object, wherein the method comprises: generating and storing in a memory, for a group of object parts of the virtual object, an ordered sequence of at least two data sets, wherein each data set comprises one or more respective constraints, wherein each constraint specifies a respective relationship between two or more object parts in the group of object parts that are updateable by application of the constraint, wherein the first data set in the ordered sequence of data sets is a specified data set of one or more constraints and wherein said generating comprises, for each data set in the ordered sequence of data sets other than the first data set in the ordered sequence of data sets, generating each constraint in said data set based, at least in part, on one or more respective constraints of one or more data sets that precede said data set in the ordered sequence of data sets; and configuring an animation system to animate the virtual object, wherein animation of the virtual object comprises a processor of the animation system performing a series of update steps, wherein each update step comprises: for each object part in the group of object parts, updating that object part; and performing an iterative process that comprises one or more iteration steps, wherein each iteration step is arranged to apply, as necessary, the data sets in the ordered sequence of data sets, in the order for the ordered sequence of data sets, to the group of object parts. |
