US 2011/0216074 A1 · REORIENTING PROPERTIES IN HAIR DYNAMICS

Abstract

Techniques are disclosed for orienting (or reorienting) properties of computer-generated models, such as those associated with dynamic models or simulation models. Properties (e.g., material or physical properties) that influence the behavior of a dynamic or simulation model (e.g., a complex curve model representing a curly hair) may be oriented or re-oriented as desired using readily available reference frames. These references frame may be obtained using a proxy model that corresponds to the dynamic or simulation model in a less computationally expensive manner in some embodiments than some techniques for determining reference frames directly using the dynamic or simulation model. In some embodiments, the proxy model may include a smoothed version of the dynamic or simulation model. In other embodiments, the proxy model may include a filtered or simplified version of the dynamic or simulation model.

Dependent claims

A computer-implemented method for orienting properties of computer-generated dynamic or simulation models, the method comprising:

receiving, at least one computer system in a set of one or more computer systems, information specifying a first pose associated with a curve model;
receiving, at least one computer system in the set of one or more computer systems, information specifying a second pose associated with the curve model;
receiving, at least one computer system in the set of one or more computer systems, information specifying a first pose associated with a proxy model;
receiving, at least one computer system in the set of one or more computer systems, information specifying a second pose associated with the proxy model;
determining, with one or more processors associated with one or more computer systems in the set of one or more computer systems, orientation of a property associated with the second pose of the curve model based on orientation of the property with the first pose of the curve model and a difference between orientation of the property with the first pose of the proxy model and orientation of the property with the second pose of the proxy model;
and
storing information representing the determined orientation of the property associated with the second pose of the curve model in a storage device associated with the set of one or more computer systems.
