Interactive stereoscopic image display system for personal computers

We have developed an experimental stereoscopic display system for personal computers that utilizes a lenticular array and a high-resolution color liquid crystal display panel. This article discusses the principles of stereopsis used in the system, describes the systems mechanism and features, and evaluates the performance of its graphics system. We also developed a color image quantization algorithm specifically for this display device. In addition, we proposed a technique for interactive 3D manipulation of objects, which uses two trackballs to allow movement and rotation through six degrees of freedom.

Concept and tools for interactive graphics-A-IDAS

Abstract This paper describes a graphics system, which has been and is being developed at IBM Japans Tokyo Scientific Center as a research prototype, and introduces a geographical data processing system as its application example. The graphics system, called Advanced Integrated Designers Activity Support (A-IDAS) System, provides not only graphic hardwares and softwares, but also a database package with a relational form and a software managing a conversational environment. Since these softwares are general purpose aids, they are effective for establishing various kinds of application systems easily and rapidly. A geographical data processing system is introduced as an example of utilization of the aids.
