摘要： In an animation processing system, generating images to be viewable on a display using a computer that are generated based on scene geometry obtained from computer readable storage and animation data representing changes over time of scene geometry elements, but also images can be modified to include shading that is a function of positions of objects at other than the current instantaneous time for a frame render such that the motion effect shading would suggest motion of at least one of the elements to a viewer of the generated images. Motion effects provide, based on depiction parameters and/or artist inputs, shading that varies for at least some received animation data, received motion depiction parameters, for at least one pixel, a pixel color is rendered based on motion effect program output and at least some received scene geometry, such that the output contributes to features that would suggest the motion.

摘要： A method is provided for sketch segmentation via smart scribbles, the results of which are especially suitable for interactive real-time graphics editing applications. A vector-based drawing may be segmented into labels based on input scribbles provided by a user. By organizing the labeling as an energy minimization problem, an approximate solution can be found using a sequence of binary graph cuts for an equivalent graph, providing an optimized implementation in a polynomial time suitable for real-time drawing applications. The energy function may include time, proximity, direction, and curvature between strokes as smoothness terms, and proximity, direction, and oriented curvature between strokes and scribbles as data terms. Additionally, the energy function may be modified to provide for user control over locality control, allowing the selection of appropriately sized labeling regions by scribble input speed or scribble input pressure. Once the drawing is labeled, a wide range of drawing applications are enabled.

摘要： An animation system can vectorize an image by generating, from an input drawing, a dataset corresponding to vector and digital representations of the input drawing such that a rendering engine could render an image having features in common with the input drawing from the representations, as a collection of strokes and/or objects rather than merely a collection of pixels having pixel color values. A vectorizer might receive an input image, generate a particle clustering data structure from a digitization of the input image, generate a stroke list, wherein strokes in the stroke list correspond to clusters of particles represented in the particle clustering data structure, generate a graph structure that represents connections between strokes on the stroke list, and determine additional characteristics of a stroke beyond the path of the stroke, additional characteristics being stored such that they correspond to strokes. The strokes might be generated using global topology information.

摘要： A camera control system is provided that uses global planning to compute large, occlusion free camera paths through complex environments, incorporating visibility of a focus point into the search strategy, so that a path is chosen along which the focus target is in view or, in general, to compute a visibility graph. A visibility roadmap data structure permits precomputation of coarse representations of collision-free paths through an environment, together with estimates of pair-wise visibility between scene portions. At runtime, path planning can be done using the precomputed roadmap values to find a coarse path, and then refined to the camera path using occlusion maps computed on-the-fly. Iterative smoothing, together with a physically-based camera model, can be used to have the path followed by the camera smooth in both space and time. The data structure can be adapted at runtime to deal with dynamic occluders that move in an environment.

摘要： Techniques are disclosed for performing image space reprojection iteratively. An insignificant parallax threshold depth is computed for a source image. Portions of the image having depth values greater than the insignificant parallax threshold depth may be shifted uniformly to produce corresponding portions of the reprojection (target) image. An iterative fixed-point reprojection algorithm is used to reproject the portions of the source image having depth values less than or equal to the insignificant parallax threshold depth. The fixed point reprojection algorithm quickly converges on the best pixel in the source image for each pixel in a target image representing an offset view of the source image. An additional rendering pass is employed to fill disoccluded regions of the target image, where the reprojection algorithm fails to converge.

The method includes determining a first set of mesoscopic details associated with an object by applying a filter to an image of an object, where mesoscopic details included in the first set of mesoscopic details are detectable in the image of the object and are not detectable when generating a coarse geometry reconstruction of the object, and generating a three-dimensional model for the object by modulating the coarse geometry with the first set of mesoscopic details.
