According to at least one embodiment, a method for generating a mesh deformation of a facial model includes: generating a first plurality of deformation maps by applying a first plurality of neural network-trained models; extracting a first plurality of vertex offsets based on the first plurality of deformation maps; and applying the first plurality of vertex offsets to a neutral mesh of the facial model to generate the mesh deformation of the facial model.

Fast and deep facial deformations

Systems, methods, and computer-readable medium for approximating mesh deformations for character rigs are disclosed. An embodiment includes applying a first deformation function to one or more mesh elements to determine an intermediate position based on a transform to a first structural element, wherein the one or more mesh elements are assigned to the first structural element, generating an offset based on a second deformation function for the one or more mesh elements using a deformation function approximation model, wherein the offset is a positional offset of the one or more mesh elements from the intermediate position to a target position corresponding to the transform applied to the first structural element, and generating a combined mesh deformation for the one or more mesh elements by combining the intermediate position and the offset.

Approximating mesh deformations for character rigs

A skin deformation system for use in computer animation is disclosed. The skin deformation system accesses the skeleton structure of a computer generated character, and accesses a user's identification of features of the skeleton structure that may affect a skin deformation. The system also accesses the user's identification of a weighting strategy. Using the identified weighting strategy and identified features of the skeleton structure, the skin deformation system determines the degree to which each feature identified by the user may influence the deformation of a skin of the computer generated character. The skin deformation system may incorporate secondary operations including bulge, slide, scale and twist into the deformation of a skin. Information relating to a deformed skin may be stored by the skin deformation system so that the information may be used to produce a visual image for a viewer.

Multipoint offset sampling deformation

Search-based matching for multiple parameter sets in computer animation is disclosed. The search-based matching method can include receiving a selection of a first set of joint parameters in a first model to match to a second set of joint parameters in a second model, currently in operation, for an appendage of a computer-generated object. The method can also adjust the selected first set of joint parameters to match the second set of joint parameters. The method can further compare the adjusted first set of joint parameters to the second set of joint parameters. Based on the comparison, the method can switch from the second model to the first model and replace the second set of joint parameters with the adjusted first set of joint parameters. The method can then output the replacement first set of joint parameters for rendering the appendage of the object.
