Systems and methods for traversal selection of components of a geometric model are disclosed. An embodiment includes displaying a plurality of components corresponding to a geometric model, selecting a first component, receiving a first input indicating a first direction for selecting a next component, wherein the next component is connected to the first component by an edge, identifying one or more candidate edges connected to the first component for selecting the next component, determining an angle between an indicated direction vector corresponding to the indicated first direction and each of the one or more candidate edges, and selecting a second component as the next component, wherein the second component is connected to the first component via a particular candidate edge forming a smallest angle with the indicated direction vector.

Systems and methods for performing MOS skin deformations are provided. In one example process, the in vector of a MOS transform may be manually configured by a user. In another example process, a slide/bulge operation may be configured to depend on two or more MOS transforms. Each of the MOS transforms may be assigned a weight that represents the transform's contribution to the overall slide/bulge. In yet another example process, a bulge operation for a MOS vertex may be performed in a direction orthogonal to the attached MOS curve regardless of the direction of the attachment vector. In yet another example process, a ghost transform may be inserted into a MOS closed curve and used to calculate skin deformations associated with first transform of the MOS closed curve.

Multipoint offset sampling deformation techniques

A computer-based animation method and system for deforming animated characters (people, animals, etc.) using a volume preserving and collision resolution process for the animation. Parts of a character are deformed by a soft mesh deformation to emulate skin deformation due to flesh and muscle movement driven by the rigid body animation along the character's joints. Resolution of the interpenetration or volume loss of deformed parts is needed for smooth and realistic animation. The present method and system enable automatic collision resolution, allowing local deformations on two intersecting parts of a character so the parts no longer interpenetrate, while preserving the volume and general shape of the two parts, e.g., the character's torso and a limb.
