【摘要】：虚拟场景漫游技术是虚拟现实技术的重要组成部分。虚拟场景漫游技术是指利用高性能的计算机软硬件,产生逼真的“虚拟环境”,使用户获得身临其境般的感官体验。虚拟场景漫游技术广泛应用于：未来城市建设规划预览、产品展示、异地景观欣赏、医学、航空航天等领域,并得到了快速的发展,但大多数漫游系统中缺少虚拟角色和交互功能,这影响了场景的真实感和沉浸感。因此在虚拟场景漫游系统中添加虚拟角色和交互功能非常重要。虚拟场景漫游系统的研究主要分为场景、人物模型搭建,人物动作制作以及漫游系统编写。本文通过查阅国内外文献,研究学习了场景建模、动作控制以及虚拟漫游等相关算法和技术。场景模型和角色模型是对现实世界的模拟,其真实程度直接影响了用户的感官体验。运动控制和交互功能提升了用户的参与度,增强了漫游系统的沉浸感。在研究虚拟场景漫游技术中,本文主要研究和实现了以下内容：(1)以Quest3D软件为虚拟场景漫游开发平台,研究了多边形和曲面建模技术并与纹理映射算法相结合构建了具有真实感的虚拟场景和角色模型；(2)分析了关节动画算法、渐变动画算法和骨骼蒙皮动画算法,利用骨骼蒙皮技术和关键帧技术制作了虚拟角色的交互动作；(3)应用了Quest3D独特的元件编程方法,实现了虚拟角色的动作控制、视角切换以及自动感应喷泉等交互功能；(4)通过系统发布,完成了具有虚拟角色的场景漫游系统。虚拟场景漫游系统的开发和实现让用户欣赏了虚拟场景中宏伟的建筑和美丽的自然风光,同时虚拟角色的引入更提升了用户的参与度,增强了虚拟漫游系统的真实感和沉浸感。
[Abstract]:The virtual scene roaming technology is an important part of virtual reality technology. The virtual scene roaming technology refers to the use of computer hardware and software with high performance, generate a realistic virtual environment, users experience a sense. Personally on the scene of virtual scene roaming technology is widely applied in the future city construction planning preview, product display, remote landscape appreciation, medical, aerospace and other fields, and has developed rapidly, but most of the lack of virtual roaming system role and interaction function, which affects the scene realism and immersion. Therefore the virtual role and interaction function is very important to add in the roaming system of virtual scene roaming system of virtual scene. The research is mainly divided into the scene figure, model structures, writing action figures making and roaming system. In this paper, through literature study, scene modeling, motion control Virtual roaming system and related algorithms and techniques. The scene model and role model is a simulation of the real world, the real level directly affects the user's sensory experience. The motion control and interactive function to enhance the participation of users, enhance the roaming system. In the sense of immersion in the virtual scene roaming technology research, this paper mainly studies and the following contents: (1) based on Quest3D software development platform of virtual scene roaming, the polygon and surface modeling technology and combined with texture mapping algorithm for constructing virtual scene and the role of the realistic model; (2) analysis of the joint animation animation algorithm, gradient algorithm and skeleton animation algorithm, interactive the action made by role virtual skin and key frame technology; (3) the application of component programming method of Quest3D unique, realized virtual character movement control, From the perspective of switching and automatic induction fountain and other interactive features; (4) the system release, complete the scene roaming system with virtual roles. Development and Realization of virtual scene roaming system allows users to enjoy the virtual scene in the magnificent architecture and beautiful natural scenery, while the introduction of virtual characters but also enhance the participation of users. Enhanced virtual roaming system of realistic and immersive.
