SYSTEMS AND METHODS FOR CROSS-APPLICATION AUTHORING, TRANSFER, AND EVALUATION OF RIGGING CONTROL SYSTEMS FOR VIRTUAL CHARACTERS
Various examples of cross-application systems and methods for authoring, transferring, and evaluating rigging control systems for virtual characters are disclosed. Embodiments of a method include the steps or processes of creating, in a first application which implements a first rigging control protocol, a rigging control system description; writing the rigging control system description to a data file; and initiating transfer of the data file to a second application. In such embodiments, the rigging control system description may be defined according to a different second rigging control protocol. The rigging control system description may specify a rigging control input, such as a lower-order rigging element (e.g., a core skeleton for a virtual character), and at least one rule for operating on the rigging control input to produce a rigging control output, such as a higher-order skeleton or other higher-order rigging element.
1 . A method comprising:
receiving, from a first application that implements a first rigging control protocol, a first rigging control system description, the first rigging control description defined according to the first rigging control protocol and specifying at least one rigging control input and at least one rule for operating on the rigging control input to produce at least one rigging control output;
converting the first rigging control description into a second rigging control description defined according to a second rigging control protocol, different from the first rigging control protocol, such that a respective rigging control input in the second rigging control description results in the same rigging control output as the respective rigging control input in the first rigging control description;
writing the second rigging control description to a data file; and
initiating a transfer of the data file to a second application that implements the second rigging control protocol.
