Chapter 14 Virtual reality 14.1 An Introduction to and history of Virtual reality The concept of a room with graphics projected from behind the walls was invented at EvL in 1992. The images on the walls are usually in stereo to give a depth cue. The main advantage over ordinary graphics systems is that the users are surrounded by the projected images. which means that the images are the users'main field of vision. This is usually called a "CAVE, CAVE Automatic Virtual Environment The first Cave(as well as the concept) was created by the faculty, staff, and students at EVi 具有墙后投影生成图像的房间的概念是1992年在EVL发明的。墙上 的图景通常是立体的以便能表现出深度。与普通的图形系统相比,它 的主要优势在于用户被投影图像所包围,这意味着这些图景是用户的 主要视野。它通常被称为CAvE,即洞穴式自动虚拟环境。第一台 CAVE(与其概念)是由EVL的全体教职员和同学共同创造的 《什第机专出美语 14-8Chapter 14 Virtual Reality 计算机专业英语 14-8 The concept of a room with graphics projected from behind the walls was invented at EVL in 1992.
