Systems and methods deforming a mesh of a target object in real-time in response to a collision with a collision object are disclosed. An embodiment includes determining an inwardly deformed position of a first vertex of the mesh based on an intersection point of a boundary associated with the collision object with a ray, the ray connecting a point of an internal element of the target object with a reference position of the first vertex, wherein the inwardly deformed position of the first vertex corresponds to a first deformation magnitude of the first vertex from the reference position to the inwardly deformed position.

Real-time collision deformation

Systems and methods for dynamic contour volume deformation are disclosed. An embodiment includes applying a deformation to a point of a volumetric mesh, wherein a plurality of tessellations of the volumetric mesh are identified and wherein each tessellation is a tetrahedral mesh, identifying a deformation point associated with a first polyhedron of the volumetric mesh, determining a barycentric coordinate representation of the deformation point with respect to each tetrahedron of the plurality of tessellations, determining, for each tessellation of the first polyhedron, weight values with respect to the deformation point for vertices of each tetrahedron which correspond to natural vertices of each tetrahedron, and determining, based on the determined weight values, a new position of the identified deformation point represented as a weighted sum determined from the barycentric coordinate representations.

Dynamic contour volume deformation

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

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.
