True Virtual Reality Systems

虚拟现实系统向用户提供与用户位置和观看方向相对应的实时计算机图形图像。在真正的虚拟现实系统中，图像具有令人信服的真实感。本研究涉及一个真正的虚拟现实系统的软件组件的设计。这个设计有三个方面。一个是生成图像的渲染系统的设计。第二个是基于感知的显示软件的设计，将图像放在显示硬件上。第三个是控制系统，它使用来自显示组件的信息来定义呈现组件使用的空间相关的错误边界。

A virtual reality system presents a user with real-time computer graphics images that correspond to the user's position and viewing direction. In a true virtual reality system, the images are convincingly realistic. This research is concerned with the design of the software components of a true virtual reality system. There are three facets of this design. One is the design of the rendering system that produces the images. The second is the design of the perceptually based display software that puts the images on display hardware. The third is the controlling system that uses information from the display component to define the spatially dependent error bounds used by the rendering component.
