REU Supplement: CISE Infrastructure Instrumentation: ACTIVE (Animated Color 3D Interactive Visual Environments)

该合同将为高性能图形工作站网络提供资金，以支持建筑可视化环境的研究。本研究的目标是：1。创建可用于在高性能工作站上快速生成特定于应用程序的、面向视觉的计算环境的工具；2. 在大规模并行算法和架构、异步和分布式系统以及超大规模集成电路设计等应用领域构建原型环境；3. 将这些原型用于三个应用领域的研究。构建环境的方法将基于声明性语义概念架构，其中每个环境都被指定为与用户交互的底层语义模型的接口。环境总是将屏幕显示作为底层模型当前状态的表示来维护，这样当模型状态发生变化时，表示就会自动发生变化。底层模型的状态和屏幕显示之间的映射是根据必须维护的所需关系以声明式的方式定义的，而不是根据用于维护它的精确程序定义的。这种方法将需要在用户界面管理、知识库和声明性语言方面取得进展，这些都是本部门活跃的研究领域。

This award will provide funds for a network of high-performance graphics workstations to support research on building visualization environments. The goals of the research are to: 1. Create tools that can be used to rapidly generate application- specific, visually-oriented computing environments on high-performance workstations; 2. Build prototype environments in the application areas of massively- parallel algorithms and architectures, asynchronous and distributed systems, and VLSI design; 3. Use these prototypes for research within the three application areas. The approach to building environments will be based on a declarative semantic conceptual architecture, in which each environment is specified as an interface to an underlying semantic model with which the user interacts. The environment always maintains the screen display as a presentation of the current state of the underlying model, so that the presentation automatically changes when the state of the model changes. The mapping between the states of the underlying model and the screen display is defined declaratively, in terms of the desired relationship that must be maintained, and not on the precise program used to maintain it. This approach will require advances in user interface management, knowledge bases, and declarative languages, which are active research areas in the department.
