Data Illustrator: Augmenting Vector Design Tools with Lazy Data Binding for Expressive Visualization Authoring

Abstract: Building graphical user interfaces for visualization authoring is challenging as one must reconcile the tension between flexible graphics manipulation and procedural visualization generation based on a graphical grammar or declarative languages. To better support designers' workflows and practices, we propose Data Illustrator, a novel visualization framework. In our approach, all visualizations are initially vector graphics; data binding is applied when necessary and only constrains interactive manipulation to that data bound property. The framework augments graphic design tools with new concepts and operators, and describes the structure and generation of a variety of visualizations. Based on the framework, we design and implement a visualization authoring system. The system extends interaction techniques in modern vector design tools for direct manipulation of visualization configurations and parameters. We demonstrate the expressive power of our approach through a variety of examples. A qualitative study shows that designers can use our framework to compose visualizations.

Potential Flow Theory and Operation Guide for the Panel Code PMARC

Abstract: The theoretical basis for PMARC, a low-order panel code for modeling complex three-dimensional bodies, in potential flow, is outlined. PMARC can be run on a wide variety of computer platforms, including desktop machines, workstations, and supercomputers. Execution times for PMARC vary tremendously depending on the computer resources used, but typically range from several minutes for simple or moderately complex cases to several hours for very large complex cases. Several of the advanced features currently included in the code, such as internal flow modeling, boundary layer analysis, and time-dependent flow analysis, including problems involving relative motion, are discussed in some detail. The code is written in Fortran77, using adjustable-size arrays so that it can be easily redimensioned to match problem requirements and computer hardware constraints. An overview of the program input is presented. A detailed description of the input parameters is provided in the appendices. PMARC results for several test cases are presented along with analytic or experimental data, where available. The input files for these test cases are given in the appendices. PMARC currently supports plotfile output formats for several commercially available graphics packages. The supported graphics packages are Plot3D, Tecplot, and PmarcViewer.

Table-top spatially-augmented realty: bringing physical models to life with projected imagery

Abstract: Despite the availability of high-quality graphics systems, architects and designers still build scaled physical models of buildings and products. These physical models have many advantages, however they are typically static in structure and surface characteristics. They are inherently lifeless. In contrast, high-quality graphics systems are tremendously flexible, allowing viewers to see alternative structures, facades, textures, cut-away views, and even dynamic effects such as changing lighting, moving automobiles, people, etc. We introduce a combination of these approaches that builds on our previously-published projector-based spatially-augmented reality techniques. The basic idea is to aim multiple ceiling-mounted light projectors inward to graphically augment table-top scaled physical models of buildings or products. This approach promises to provide very compelling hybrid visualizations that afford the benefits of both traditional physical models, and modern computer graphics, effectively "bringing to life" table-top physical models.

Method for implementing a computer game

Abstract: A method, implemented as computer code being executed by one or more processors, in which computer game graphics for a casual, social game are shown on a display of a computing device, where the casual, social game is downloaded as an app to a smartphone and/or tablet computer and can be accessed or played using a social network application or environment; and in which one or more of the processors are programmed such that: a notification is automatically generated if a player is stuck at a level for more than a defined time or after more than a defined number of attempts to pass that level, the notification alerting friends of the player so that they can assist him or her.

Private addressing in a multi-processor graphics processing system

Abstract: Systems and methods for private addressing in a multi-processor graphics processing subsystem having a number of memories and a number of graphics processors. Each of the memories includes a number of addressable storage locations, and storage locations in different memories may share a common global address. Storage locations are uniquely identifiable by private addresses internal to the graphics processing subsystem. One of the graphics processors is able to access a location in a particular memory by referencing its private address.
