摘要： 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.

摘要： A system and method for characterizing and adjusting an offset between displayed stereo image pairs allows for calibration of the stereo image content for each display environment. The stereo image content is typically authored assuming a particular display image size. When the stereo image content is displayed in a display environment that does not conform to the particular display image size the offset between displayed stereo image pairs is increased or decreased, resulting in a viewing experience that is different than intended. In some cases, the viewer may experience discomfort due to eye strain or eye fatigue. Adjusting the offset during the playback of the stereo image content may improve the viewer experience.

摘要： A file format that includes a constant section and a varying section. The constant section provides a referencing scheme that references the various components that comprise the scene, as well as a listing of attributes of the scene that are modifiable. Within the same file format, the varying section provides an overriding mechanism to modify the attributes that are available to be modified. Accordingly, the disclosed file format can access cached animated geometry directly and/or aggregate other files via the aforementioned referencing and sparse override semantics. This allows the same set of inspection, manipulation, and rendering tools to be used throughout the rendering pipeline, from asset creation to final rendering.

摘要： One or more techniques to reduce or eliminate the false depth of objects that move along the axis of ocular separation when displayed using time division multiplexing. Experiments can be performed to determine a perceived depth of an object moving with known velocity. Then, when rendering stereoscopic image pairs, the location of the object can be modified to change the perceived stereoscopic depth of the object to compensate for the false depth. In one technique, the images can be displayed with alternating left- and right-precedence to reduce the perception of false depth.

摘要： A system, apparatus and method of rendering images for computer graphics or animation at multiple levels of detail or resolution. The invention uses a hierarchical data structure and provides methods of generating and using that structure for rendering images. The invention generates a data structure containing data elements representing multiple resolutions of data and then determines a desired resolution for the image. The data elements in the data structure corresponding to the desired resolution are accessed and each data element in the accessed data is associated with a renderable primitive. The image is then rendered by processing the renderable primitive associated with each data element.

摘要： 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.

摘要： A computer-implemented method for generating a circular scratch highlight. The method includes generating a plurality of texture planes, where each texture plane includes a plurality of copies of a scratch texture oriented in the same direction; generating a combined texture by combining the plurality of texture planes at different angles; applying the combined texture to a surface of an object; calculating a specular gradient vector based on a light vector and a reflectance vector, wherein the specular gradient vector points in a gradient direction of a specular highlight; and generating the circular scratch highlight by assigning, for each of a plurality of points on the surface of the object, a separate weight value corresponding to each texture plane in the combined texture based on how closely an orientation of the texture plane at the point corresponds to a scratch vector that is perpendicular to the specular gradient vector.
