Animation data transfer between geometric models and associated animation models

摘要

Systems and techniques are provided for transferring changes in animation data between geometric models of a character having different resolutions. For example, systems and techniques are provided for transferring changes in geometric properties between the geometric models. A method may include obtaining a first geometric model of the character and a second geometric model of the character, the geometric models having different resolutions with different numbers of data points. The method may further include determining one or more correspondences between data points of the first geometric model and data points of the second geometric model. The correspondences include one or more data points of the first geometric model that overlap with one or more data points of the second geometric model. The method may further include determining a feature change in the first geometric model, which includes a change in a geometric property of at least one data point of the first geometric model relative to an initial geometric property of the at least one data point prior to the change. The method may further include transferring the feature change in the first geometric model to the second geometric model using the one or more correspondences, including interpolating a change in a geometric property of at least one data point of the second geometric model.
