摘要： Realistic computer generated character animation is achieved by modeling skin or other covering as a separate a quasi-static surface elastically tied to an underlying detailed, articulated model controlled by the animator. The result, automatically incorporates realistic stretching, and sagging, and the combined effect of multiple overlapping animation controls while retaining for the animator frame-by-frame control of a detailed model of the character.

摘要： User interface display layouts are provided that draw a user's attention to a specific element or elements by de-emphasizing the surrounding content, but without removing the de-emphasized content from the interface. This ability to maintain the whole presentable layout with visibility layers and without layout changes provides a useful navigation experience for the user as it is clear where the user's attention should go and yet the surrounding content is still subtly there, constantly reminding the user of the other available content. De-emphasis of certain content items is achieved by modifying display characteristics of those content items relative to a base display level, for example by lowering saturation, lowering opacity, and/or de-focusing (as if the user is looking through a camera) and modification can be done variably. Driven by a relevancy score, each content item in a display layout can be de-emphasized more or less depending on which content is more meaningful to the user's filtering actions.

摘要： An edge-preserving diffusion filter maintains the sharp edges in images while smoothing out image noise. An edge-preserving diffusion filter applies an edge-preserving smoothing filter to an image to form a filtered image. The modified image is then blurred by a blurring filter to form a blurred image. The modified image and the blurred image are blended together to form an output image based on an error metric associated with each pixel. The edge-preserving diffusion filter may be utilized to perform a multilevel decomposition of the image. The edge-preserving diffusion filter may be applied to an unfiltered image to produce a base image. The difference between the unfiltered image and the base image defines a detail image. The detail image may be used as the input for recursively generating additional levels of detail. The multilevel decomposition may utilize filter kernels associated with different contrast levels for each iteration.

摘要： Local histogram and local histogram-based functions can be determined by generating offset-kernel images based on domain-shifted tonal filter kernels. The offset-kernel images can be reused for multiple image locations and/or local neighborhood sizes, shapes, and weights. A neighborhood filter representing the desired local neighborhood size, shape, and frequency domain characteristics is applied to each of the offset-kernel images. Neighborhood filters may include a temporal dimension for evaluating neighborhoods in space and time. Neighborhood filtered offset-kernel images' values represent samples of local histogram or local histogram-based function corresponding with the domains of their associated domain-shifted tonal filter kernels. Arbitrary functions may be used as tonal filter kernels. A histogram kernel may be used to sample values of local histogram functions. A tonal filter kernel that is a derivative or integral of another tonal filter kernel may be used to sample a derivative or integral, respectively, of a function.

摘要： A method of globally analyzing intersections between objects in computer animation includes providing objects represented by meshes, with each of the meshes being formed by a set of vertices, where a set of pairs of vertices defines a set of edges of the mesh. All edges of the meshes are checked to determine if the edges intersect with any of the meshes. An intersection path, formed by the intersection of the meshes, is traced and which vertices that are contained within the intersection path are determined. A polarity of each of the contained vertices is set to indicate that those vertices are contained within the intersection path. The analysis forms the backbone of a collision-response algorithm for unoriented objects such as cloth that is better than previous existing algorithms. The analysis also allows objects to be simulated even when hand-animated elements of the simulation have extreme amounts of interpenetration. Finally, simply displaying the nature and extent of the data found from the analysis provides extremely useful feedback to an end-user.

摘要： A method to reduce NOx, emissions from diesel fuel alcohol microemulsions (E-diesel) is taught. Ethanol is stripped from the microemulsion and entered into the exhaust gasses upstream of the reducing catalyst. The method allows diesel engines to meet new, lower emission standards without having to carry separate fuel and reductant tanks.

摘要： An animation creator authors a transition between two different pre-authored motions of a degree of freedom of an object such as an animatronic or virtual character. The author selects an arbitrary position to begin the transition and the transition ends at the position where a subsequent state of a degree of freedom of the object begins. The selected position is arbitrary because an initial state of the degree of freedom of the object is not known until the complete motion of the object is determined. The transition is transformed to begin where the initial state ends and to end where the subsequent state begins. The transition is transformed to retain the general shape of the authored transition and to provide the same quality of motion as the pre-authored motions. The transformed transition may be scaled in time such that limits of velocity and/or acceleration for the object are not violated.

摘要： An input device for controlling an object includes a joystick and a modal switch. A user may use the modal switch to select a subset of degrees of freedom of the object. The joystick may then be used to control a change over time of the selected subset, where the change over time is functionally depend on both a motion of the joystick and a state of the selected subset. A method for controlling an object via the input device is also provided. The method includes receiving inputs indicating a selection by the modal switch of a subset of degrees of freedom of the object, and a motion of the joystick. A configuration of the selected subset is then caused to be changed based on the motion of the joystick and a state of the selected subset.

摘要： A computer-implemented method for generating depth-of-field effects includes receiving information specifying an input image rendered using a pinhole camera. A first set of circles of confusion associated with portions of the input image are determined based a set of parameters associated with the pinhole camera. The first set of circles of confusion are then associated with heat conductivity of a medium. The portions of the input image are blurred according to heat diffusion in the medium to generate a first output image having a first depth-of-field effect.
