摘要： A method, system, apparatus, and program product for displaying a program slice diagram, which represents source code. The program slice diagram includes a directed graph that has multiple nodes and arcs connecting the nodes. Nodes can correspond to statements within a selected subroutine of the source code, variable references outside the subroutine, or calls made to other subroutines that are considered part of the program slice. Arcs represent data flow dependencies between the nodes. In another aspect, the invention encompasses a software environment for visualizing source code that includes a code browser, a block-level abstract syntax tree viewer, a program slice browser, and a template viewer. This software visualization environment is integrated, allows cross-referencing between its components, and is coupled with a performance visualization environment.

摘要： Methods and apparatus for reproducing the appearance of a photographic print on a display device are disclosed. An environment model is built from received light conditions at a light sensor attached to a display surface. The environment model and a surface model are applied to an input image to generate an output image. The surface model represents reflective characteristics of a simulated surface on which display of the input image is simulated. The output image simulates an effect of the received light conditions on the input image as simulated on the surface.

摘要： Systems and methods for simulating liquid-on-lens effects may provide an interface through which users can add and/or manipulate fluids on a virtual camera lens. A physically based fluid simulation may simulate the behavior of the fluid as it is deposited on and/or manipulated on the virtual lens, and determine the distribution of the fluid across the lens. A ray tracing technique may be employed to determine how light is refracted through the virtual lens and the fluid, and to render a distorted output image as seen through the lens and the fluid. As the fluid is manipulated, corresponding changes in the image may be displayed in real time. The input image may be an existing single image or a direct camera feed (e.g., of a tablet type device). The user may select a fluid type and/or various fluid properties for the image editing operation.

摘要： Techniques for improving the performance of vector-based, fluid motion simulation techniques. The techniques may be implemented in procedural painting algorithms that employ a vector-based, fluid motion simulation technique to help achieve dynamic, serendipitous behaviors of painting at good interactive rates even on relatively low-powered devices. Instead of employing polygons in a procedural painting algorithm that are combinations of pigment and water, a technique may be employed in which the polygons are separated into pigment polygons and water polygons. The water polygons are not rendered; only the pigment polygons are rendered. To improve the performance of the wetness determination at vertices of the pigment polygons, a technique may be used that first rasterizes all of the water polygons into a buffer, which may be referred to as a wetness layer or wetmap; the wetness at a vertex is then determined by sampling this buffer or layer at the vertex's position.

In some implementations, a method includes determining one or more characteristics of each of a plurality of source images and determining one or more similarities between the one or more characteristics of different source images. The source images are grouped into one or more groups of one or more target images based on the determined similarities. The method determines and applies one or more color corrections to the one or more target images in at least one of the groups.

摘要： Systems, methods, and apparatus for simulating natural media painting in a digital painting application (or painting simulation module) may more accurately simulate real world painting techniques than conventional painting simulation applications. The digital painting application (or simulation module) may provide a small set of physically meaningful parameters (e.g., canvas wetness, drying rate, and pickup mix ratio). By setting the values of these parameters (or overriding default values for a selected paint type), the user may better control the appearance of brush strokes made by a virtual paint brush on a digital canvas. For example, the length of a brush stroke, the amount of streaking caused by paint picked up during the brush stroke, and/or the mix of paint deposited from a pickup buffer and a reservoir buffer of a brush model may be affected by changing the values of these parameters, thus allowing users to create different realistic painting effects.

摘要： A method, system, and computer-readable storage medium are disclosed for simulation of an erodible tip. A brush tool representing an erodible media is modeled as a height map. Information is collected about a user manipulation of a stylus representing a stroke made on a virtual canvas with the brush tool. A mark to be made on the virtual canvas is determined dependent on the brush tool model and the collected information. The determined mark is rendered. A change in the height map of the brush tool due to the stroke is determined dependent on the brush tool model and the collected information. One or more subsequent marks are rendered in response to manipulation of the brush tool dependent on the determined change in the height map.

摘要： Techniques for improving the performance of vector-based, fluid motion simulation techniques in procedural painting algorithms. The techniques may be implemented in procedural painting algorithms that employ a vector-based, fluid motion simulation technique to help achieve dynamic and serendipitous behaviors of watercolor painting at good interactive rates even on relatively low-powered devices. The techniques may include resampling the vertices of pigment polygons after growth at least at some iterations of the algorithm to provide smoother, more uniform growth; rasterizing dried pigment polygons into a texture so that the dried polygons are not rendered at each iteration of the algorithm; and rendering only a subset of live pigment polygons at each iteration of the algorithm. Polygons used by the techniques may be separated into static water polygons and dynamic pigment polygons.

摘要： Systems, methods, and apparatus for simulating natural media painting in a digital painting application (or painting simulation module) using a two-layer model of a virtual paint brush may more accurately simulate real world painting techniques than conventional painting simulations. A two-layer brush model may include a reservoir buffer and a pickup buffer to separately represent the paint stored in the belly of a paint brush tip and paint that has been picked up on the surface of the brush tip during a brush stoke, respectively. The two-layer brush model may also include methods that automatically control how virtual paint moves between these layers and a digital canvas. In simulations that employ this two-layer brush model, virtual paint may be deposited on the digital canvas directly from both of the buffers. The amount of paint deposited from each buffer (and/or the ratio of the amounts) may be configurable by a user.

摘要： A method and apparatus for computing direct lighting in a scene is described. For a sparse set of points in the scene, occlusion information for the points and each of one or more light sources may be computed and stored. For all other surface points in the scene, nearby sample points are examined to determine if their occlusion information agrees. For any light source for which nearby sample points do not agree, lighting computation may be performed, e.g. by the casting of shadow rays. Such areas comprise regions in penumbra or shadow boundaries. For all other regions, it is assumed that they are fully lit or fully occluded, and thus the casting of shadow rays can be avoided.
