Abstract

The design and construction of virtual reality environments involve technologies such as computer graphics, image processing, pattern recognition, intelligent interface, artificial intelligence, voice recognition, network, parallel processing, and high-performance computing. Some researchers insist that object-oriented and agent-oriented technologies are fundamental for virtual reality system design. This paper applies artificial intelligence to the design of virtual reality systems. Agents are constructed by using object-oriented methods and a set of underlying computing models, such as neural networks, genetic algorithms, expert systems, and plan managers. Some object-oriented frameworks of these computing models are presented to illustrate this approach. The example of a spaceship game will illustrate interactions among environments, agents, and underlying computing models. The approach and reusable class library presented herein can be applied to various virtual reality environment simulations and intelligent applications.

Highlights

  • The design and construction of virtual reality environments require technologies such as computer graphics, image processing, pattern recognition, intelligent interface, artificial intelligence, voice recognition, network, parallel processing, and high performance computing

  • At the same time we present a set of underlying computing models such as neural networks, genetic algorithms, expert systems, and plan managers to support agents

  • Plan managers are designed to handle plans that are integrated by three functions: (1) the condition judgment function that determines whether the precondition part of the plan can be matched with the current status; (2) the plan execution function that executes at each time step while the plan is active

Summary

Introduction

The design and construction of virtual reality environments require technologies such as computer graphics, image processing, pattern recognition, intelligent interface, artificial intelligence, voice recognition, network, parallel processing, and high performance computing. Reference [1] suggests that object-oriented and agent-oriented technologies are the basic methodologies for designing virtual reality systems. This paper applies artificially intelligent technologies to the virtual reality worlds, and proposes an agent-based approach to virtual reality from the standpoint of software simulation system design. A spaceship game illustrates the interactions among environment, agents, and underlying computing models. A spaceship game in Section 4 will demonstrate how to use the framework and computing models to develop a virtual environment simulation system.
