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

该奖项将为一个高性能图形工作站网络提供资金，以支持建立可视化环境的研究。该研究的目标是：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.构建大规模并行算法和架构应用领域的原型环境。异步和分布式系统以及VLSI设计；3.使用这些原型在三个应用领域内进行研究。构建环境的方法将基于声明性语义概念体系结构，其中每个环境被指定为用户与之交互的底层语义模型的接口。环境始终将屏幕显示作为底层模型的当前状态的表示形式，以便当模型的状态更改时，表示形式自动更改。底层模型的状态和屏幕显示之间的映射是声明性地定义的，根据必须维护的所需关系，而不是在用于维护它的精确程序上。这一办法将需要在用户界面管理、知识库和说明性语言方面取得进展，这些都是该部积极研究的领域。

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.
