CISE Research Instrumentation: Realistic Computer Graphics

9818344Thompson, William B.Cohen， elaine犹他大学，逼真的计算机图形。该研究仪器支持以下研究项目：-运动界面，-虚拟原型，-大规模合成环境中空间组织的感知，以及-自然场景的逼真计算机图形。该合同支持采购一个用于生成和投影高质量计算机图形的系统。该设备支持涉及沉浸式界面和逼真计算机图形的研究项目。有四个项目正在利用这一资源。改进的运动界面正在开发中，允许用户在虚拟环境中行走。计算机辅助设计（CAD）的触觉界面工作正在扩展，特别注意视觉和触觉显示的集成，以更好地传达大多数机械设计中涉及的复杂几何形状的感觉。人们正在开发方法，以便在计算机生成的图像中更准确地传达距离、比例和速度的感觉。由于目前的技术很难产生距离较远和/或尺寸较大的物体的图像，这项重要的工作可能会对该领域有所贡献。最后，对如何生成逼真的室外场景合成图像进行了分析。为了取得成功，这四项工作都需要图形渲染能力和高分辨率显示能力，作为基础设施收购的一部分。

9818344Thompson, William B.Cohen, ElaineUtah UniversityRealistic Computer GraphicsThis research instrumentation enables research projects in:- Locomotion Interfaces,- Virtual Prototyping,- Perception of Spatial Organization in Large-Scale Synthetic Environments, and- Realistic Computer Graphics for Natural Scenes.The award supports the acquistion of a system for generating and projecting high quality computer graphics. The equipment supports research projects involving immersive interfaces and realistic computer graphics. Four projects are taking advantage of this resource. Improved locomotion interfaces are being developed, allowing a user to walk through a virtual environment. Work on haptic interfaces for computer aided design (CAD) is being extended, with particular attention to the integration of visual and haptic displays to better convey a sense of the complex geometries involved in most mechanical designs. Methods are being developed for more accurately conveying a sense of distance, scale, and speed in computer generated imagery. Because current techniques have great difficulty producing images of objects which appear to be far away and/or of significant size this important work may contribute to the field. Finally, an analysis of how to generate realistic looking synthetic images of outdoor scenes is being initiated. To be successful, all four of these efforts require the graphical rendering power and high resolution display capabilities being made available as part of this infrastructure acquisition.
