虛擬環境屬性設計系統-架構與實作

Abstract

虛擬實境系統通常包含兩個部份：建構一個虛擬環境，模擬這個虛擬環境 。本論文中提出一個好的虛擬環境設計系統應具備的架構，並討論部分主 要功能。希望能提供使用者更方便的使用方式，而且更符合虛擬實境系統 的需求。在此我們比較並分析了現有系統的作法與優劣也分析了這類系統 的真正需求，然後我們提出了新的系統架構與概念。此為一個以物件導向 為主的架構，不論在使用上與系統設計上都相當強調物件導向的應用。實 做此系統時，我們利用了一個方便的"結構控制"方式讓系統在實作時更加 方便與簡單。針對所提的系統架構我們也實作了系統主要架構及部分重要 功能，並討論以物件導向方式為系統架構的實作方法。在論文的最後並討 論了這種系統可能的發展方向，並介紹了開放式屬性設定的觀念與物件繼 承方式的設計。 A virtual reality system typically consists of two parts : creating a virtual environment and simulating the virtual environment. In this thesis, we present the architecture of an ideal virtual environment attribute designing system and implements major parts of the system. The design aims are to provide a more convenient and natural way for users to design virtual environment that is able to maturely satisfy the need of virtual reality applications. We compare and analyze existing systems, examine the necessities of the system and then we present an architecture of the attribute designing system which is an object-oriented architecture. In implementing the system, we utilize a "struct control" approach that makes the implementation simpler. The system architecture and major functional components have been implemented. We also discuss the future development of the system.
