Patent number: 9582247Abstract: To prevent correlated data from being inadvertently altered by subsequent modifications or additions, changes to correlated data are automatically detected. Corrections may be automatically applied to data to preserve data correlation. Change detection data is determined from an initial correlation between source data and dependent data. The change detection data is stored in association with the dependent data. A subsequent evaluation of the data defines a current correlation between the source data and the dependent data. The current correlation is evaluated with the change detection data to determine if the current correlation differs from the initial correlation. If the current correlation between source data and dependent data does not match the initial correlation, the current correlation is reevaluated using topological; geometric, or other analysis techniques. The reevaluated correlation can be provided as part of the authored state of a computer graphics component.Type: GrantFiled: March 14, 2012Date of Patent: February 28, 2017Assignee: PixarInventors: Timothy S.

Patent number: 9275487Abstract: A method for performing non-affine deformations. The method includes receiving data representing mathematical vectors associated with elements defining an object. The elements are organized in a hierarchy, a different subset of mathematical vectors is associated with one or more elements, and the mathematical vectors within each subset are defined relative to a local coordinate space associated with each element. The method further includes determining that a first non-affine deformer is to be applied to a first set of the elements, and, for each element in the first set, applying the first non-affine deformer to world coordinate space values corresponding to the mathematical vectors within the subset of mathematical vectors associated with the element to generate modified world coordinate space values for the mathematical vectors.Type: GrantFiled: April 8, 2009Date of Patent: March 1, 2016Assignee: Pixar Animation StudiosInventors: Dirk Van Gelder, George Elkoura, Adam Woodbury

Patent number: 8154544Abstract: An embodiment of the invention creates contact deformations in objects by combining two deformations. A collider contacting an object defines a primary deformation that modifies at least a portion of the object in contact with the collider. A secondary deformation based at least in part on user-provided parameters is added in the vicinity of the primary deformation to deform nearby portions of the objects that are not in contact with the collider, providing an aesthetic contact effect. A secondary deformation specification defines the general shape of the secondary deformation. The secondary deformation specification is associated with a location based on the location of the primary deformation. In an embodiment, the modification of the object due to the secondary deformation specification is modulated by attributes of the collision points, the primary deformation, user-specified weightings, and/or weight maps.Type: GrantFiled: July 25, 2008Date of Patent: April 10, 2012Assignee: PixarInventors: Gordon Cameron, Robert H. Russ, Adam Woodbury

Patent number: 7515155Abstract: A method for animating soft body characters has a preparation phase followed by an animation phase. In the preparation phase, the skin deformation of the character model is determined for a set of basis poses. The skin deformation from posing is compactly represented in terms of the set of basis poses. In the animation phase, the set of basis poses and the skin mode response are used to create a final posed character. A desired character pose is projected onto the basis set to determine a set of basis weights. The basis weights are applied to the set of skin responses to create a skin pose response, and the skin pose responses is projected onto the basis set to create the posed character model.Type: GrantFiled: October 17, 2006Date of Patent: April 7, 2009Assignee: PixarInventors: John Anderson, Adam Woodbury

Patent number: 7307633Abstract: A method for animating soft body characters has a preparation phase followed by an animation phase. The preparation phase determines the skin deformation of a character model at skin contact points in response to impulse collisions. The skin deformation from impulse collisions are compactly represented in terms of the set of basis poses. In the animation phase, the skin impulse responses are used to create a final posed character. Regardless of the type of collision or the shape of the colliding object, the collision animation phase uses the same set of skin impulse responses. A subset of a set of skin points is selected as a set of skin collision points. A final collision response is determined from the skin collision points. The final collision response to the complete set of skin points.Type: GrantFiled: May 14, 2003Date of Patent: December 11, 2007Assignee: PixarInventors: John Anderson, Adam Woodbury

Patent number: 7262768Abstract: A method for rendering participating media effects is disclosed. At least one object having a surface is defined and a lattice, aligned with a camera, is also defined that encompasses the at least one object. A volumetric line integral is computed from the camera to lattice points in a neighborhood of a particular point on the surface of the object to obtain a value. The obtained value is filtered to obtain a volumetric line integral value for the particular point on the surface. Additionally, the set of values may be cached in memory and may be used in computing additional volumetric line integrals when applicable. The set of values determined for lattice points is filtered to determine the volumetric line integral value for a particular point on the surface.Type: GrantFiled: December 9, 2003Date of Patent: August 28, 2007Inventors: Adam Woodbury, Rick Sayre, Tom Lokovic, Tom Duff
