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.
