This project, constructing a stereoscopic, high intensity, immersive projection environment for interactive design, supports collaborative research in visualization, perception, architectural design, and computer graphics. Through collaborative efforts of computer scientists and architects, the work seeks to develop and use tools that allow the intuitive creation, manipulation, and display of data an images within a stereoscopic, high ambient intensity, multi-user, immersive projection environment, to achieve fundamental breakthroughs that facilitate the creative design process, and enhance the understanding of science behind the art of effective visual representation. At the same time, new algorithms for effective interactive rendering and manipulation of large scanned environmental datasets and new tools for physically and perceptually realistic color appearance rendering will be developed. The infrastructure contributes to the following research: Harnessing the Fullest Potential of Virtual Environment Technology for Research in Visualization and Design, Developing New Tools for Conceptual Architectural Design in Immersive Virtual Environments, New Tools for Efficient Rendering and Design Conceptualization, and Computer Aided Color Appearance Design.The first project aims at determining how to most effectively harness the special potential of virtual environment displays for data representation. Foremost will be efforts to investigate methods for facilitating and exploiting the expanded spatial understanding afforded by immersive displays, exploring the impact of employing a range of non-photorealistic representational styles in immersive virtual environments. The second builds on an immediate-mode modeling system and software, supporting the geometry creation and manipulation, and texture, image and video insertion and manipulation. Goals include offering the designer a space that supports designing (not just an empty space in which to stand); investigating the kind of contextual environment that best supports the design in its various stages; different aspects with different scales; finest expression of ideas; support of the supply and generation of information, text, image, video, and sound within the design environment; support of symbols and representation within the virtual environment; and determining those aspects of the design that are best done outside the environment and the best way to bridge the two worlds. The third develops a tool to allow modeling geometry on top of the finished sketch design, much like the experience of working with tracing paper. The last uses the panoramic display system to evaluate the results of computer aided color appearance design (CACAD) research that was performed on either cathode ray tubes or other specialized CACAD workstations. At the fundamental computer graphics level, this work is expected to expand the state of the art in virtual reality by evaluating the contribution that surface reflection makes to the illusion of "presence." The work explores whether expensive surface finish samples and controlled observing conditions can be replaced by computer graphics simulations and a "virtual color proofing" system. The impact of the research will extend to new courses in CS and architecture. The team formed the Digital Design Consortium, an outreach effort involving community leaders.

该项目为交互设计构建了一个立体的、高强度的、沉浸式的投影环境，支持可视化、感知、建筑设计和计算机图形学的合作研究。通过计算机科学家和建筑师的共同努力，这项工作旨在开发和使用工具，允许直观的创建，操作和显示数据和图像在立体，高环境强度，多用户，沉浸式投影环境中，以实现促进创造性设计过程的根本突破，并增强对有效视觉表现艺术背后的科学的理解。与此同时，将开发用于有效交互式渲染和操纵大型扫描环境数据集的新算法以及用于物理和感知上逼真的颜色外观渲染的新工具。该基础设施有助于以下研究：充分利用虚拟环境技术的潜力进行可视化和设计研究，开发沉浸式虚拟环境中概念建筑设计的新工具，高效渲染和设计概念化的新工具，第一个项目旨在确定如何最有效地利用虚拟环境的特殊潜力显示以表示数据。最重要的将是努力研究方法，促进和利用沉浸式显示器提供的扩展空间理解，探索在沉浸式虚拟环境中采用一系列非真实感表现风格的影响。第二个是建立在即时模式建模系统和软件，支持几何创建和操作，纹理，图像和视频插入和操作。目标包括为设计师提供一个支持设计的空间（不只是一个空的空间，在其中站立）;调查的上下文环境，最好地支持设计在其各个阶段的类型;不同的方面，不同的规模;最好的表达思想;支持的供应和生成的信息，文本，图像，视频和声音的设计环境;支持虚拟环境中的符号和表示;并确定在环境之外最好完成的设计方面以及连接两个世界的最佳方式。第三个开发了一个工具，允许在完成的草图设计之上建模几何图形，就像使用描图纸一样。最后使用全景显示系统来评估计算机辅助色彩外观设计（CACAD）的研究，无论是阴极射线管或其他专门的CACAD工作站上进行的结果。在基本的计算机图形学水平上，这项工作预计将通过评估表面反射对“在场”错觉的贡献来扩展虚拟现实的艺术水平。这项工作探讨了昂贵的表面光洁度样品和受控的观察条件是否可以被计算机图形模拟和“虚拟彩色打样”系统所取代。研究的影响将扩展到CS和建筑学的新课程。该团队成立了数字设计联盟，这是一项涉及社区领导人的外联工作。
