Abstract: Embodiments of the present invention are directed to beautifying freeform input paths in accordance with paths existing in the drawing (i.e., resolved paths). In some embodiments of the present invention, freeform input paths of a curved format can be modified or replaced to more precisely illustrate a path desired by a user. As such, a user can provide a freeform input path that resembles a path of interest by the user, but is not as precise as desired. Based on existing paths in the electronic drawing, a path suggestion(s) can be generated to rectify, modify, or replace the input path with a more precise path. In some cases, a user can then select a desired path suggestion, and the selected path then replaces the initially provided freeform input path.

Abstract: A technique for classifying a ray tracing intersection with a triangle edge or vertex avoids either rendering holes or multiple hits of the same ray for different triangles. The technique employs a tie-breaking scheme in which certain types of edges are classified as hits and certain types of edges are classified as misses. The test is performed in a coordinate space that comprises a projection into the viewspace of the ray, and thus where the ray direction has a non-zero magnitude in one axis (e.g., z) but a zero magnitude in the two other axes. In this coordinate space, edges are classified as one of top, bottom, left, and right, and an intersection on an edge counts as a hit if the intersection hits a top or left edge, but a miss if the intersection hits a bottom or right edge. Vertices are processed in a related manner.

Abstract: A virtual reality system includes a head-mounted display (HMD) having one or more facial sensors and illumination sources mounted to a surface of the HMD. For example, the facial sensors are image capture devices coupled to a bottom side of the HMD. The illumination sources illuminate portions of a user's face outside of the HMD, while the facial sensors capture images of the illuminated portions of the user's face. A controller receives the captured images and generates a representation of the portions of the user's face by identifying landmarks of the user's face in the captured images and performing other suitable image processing methods. Based on the representation, the controller or another component of the virtual reality system generates content for presentation to the user.

Abstract: An image editing program can include animation brushes. An animation brush enables a content creator to draw as with any other digital brush. The animation brush will automatically generate elements, such as hair or raindrops. Each element can be drawn using a set of pixels that have a particular shape, location, and/or color, as determined by parameters associated with the animation brush. The image editing program can further animate the elements by determining, for each frame of an animation sequence, updated shape, location, and/or color values for the pixels of the elements. The image editing program can then redraw the elements. Redrawing of the elements can thus produce an animation.

Abstract: Innovations in stream configuration operations and playback operations for adaptive streaming of panoramic video are described. The innovations include features of adaptive streaming of panoramic video with overlapping sections. For example, a stream configuration tool splits an input picture of panoramic video into overlapping sections. A playback tool reconstructs one or more of the sections. Because of overlap between adjacent sections, for gradual changes in a view window, the playback tool can, in effect, preemptively fetch a new section as the view window moves out of a current section into the new section. By the time the view window reaches a non-overlapping part of the adjacent, new section, the playback tool has retrieved encoded data for the new section and can reconstruct the new section. This hides network latency and stream switching latency from the viewer, and disruption of playback is avoided.

Abstract: A method of geometry corrections to properly transfer semiconductor designs on a wafer or a mask in nanometer scale processes is provided. In contrast with some prior art techniques, geometry corrections and possibly dose corrections are applied before fracturing. Unlike edge based corrections, where the edges are displaced in parallel, the displacements applied to generated geometry corrections do not preserve parallelism of the edges, which is specifically well suited for free form designs. A seed design is generated from the target design. Vertices connecting segments are placed along the seed design contour. Correction sites are placed on the segments. Displacement vectors are applied to the vertices. A simulated contour is generated and compared to the contour of the target design. The process is iterated until a match criteria between simulated and target design (or another stop criteria) is reached.

Abstract: A gradient method (GM) for constructing and using absorbing boundary conditions (ABCs) for high accuracy numerical computations of various physical phenomena which are governed by partial differential equations (PDEs) is disclosed. The PDEs to which the GM is applicable are for example: the Helmholtz equation (also known as the wave equation in the frequency domain), the elastic wave equation in the frequency domain, Maxwell's equations, and Schrodinger's equation. The GM can be used to develop ABCs for the solution of PDE problems in two or more dimensions. The GM is a tool based on two principles: (1) Any directional derivatives in an ABC must be taken in the direction of the gradient of the unknown function or functions of the PDE, and (2) any ABC using such gradient derivatives may be applied to any domain of a convex shape, even if the ABC was originally developed for domains of a restricted shape.

Abstract: Dynamic spread anti-aliasing is described. In some embodiments, a filled object is segmented into control tiles. Along the object border, multiple exterior control tiles respectively correspond to multiple curves forming the border. For each curve, one side is filled and the other is anti-aliased to smooth the appearance of the filled object. Each exterior control tile is expanded to create an expanded control tile having a spread zone that includes additional pixels. For example, a control triangle is transformed into a control rectangle, and the control rectangle is enlarged to create an expanded control rectangle by extending an edge outward and away from the curve on the side to be anti-aliased. The additional pixels of the spread zone are subjected to anti-aliasing, such as by applying alpha modulation to the pixels based on respective distances between the pixels and the curve. For subpixel zoom levels, pixel color can be adjusted.

Abstract: A procedural model enables a user to configure a global space organization function for the generation of decorative ornaments. The user provides data to seed the generation of the ornaments, as well as localized interactive edits to the generated ornaments. The procedural model iteratively places decorative elements at a subset of locations within an ornament area (or domain) based on generalized placement functions employed by the global space organization function. As such, the user is enabled to interactively generate and edit decorative ornaments via configuring the global space organization function and employing editing tools. Such functionality significantly decreases the effort typically required to generate ornate ornaments, while retaining control of the aesthetic organization and structure of the ornament. The generalized placement functions and heuristics of the global space organization function enable such control.

The scaled mask images are subtracted from the respective images and a projection angiograms are produced from these processed images.
