【摘要】：虛擬場(chǎng)景漫游技術(shù)是虛擬現(xiàn)實(shí)技術(shù)的重要組成部分。虛擬場(chǎng)景漫游技術(shù)是指利用高性能的計(jì)算機(jī)軟硬件,產(chǎn)生逼真的“虛擬環(huán)境”,使用戶(hù)獲得身臨其境般的感官體驗(yàn)。虛擬場(chǎng)景漫游技術(shù)廣泛應(yīng)用于：未來(lái)城市建設(shè)規(guī)劃預(yù)覽、產(chǎn)品展示、異地景觀欣賞、醫(yī)學(xué)、航空航天等領(lǐng)域,并得到了快速的發(fā)展,但大多數(shù)漫游系統(tǒng)中缺少虛擬角色和交互功能,這影響了場(chǎng)景的真實(shí)感和沉浸感。因此在虛擬場(chǎng)景漫游系統(tǒng)中添加虛擬角色和交互功能非常重要。虛擬場(chǎng)景漫游系統(tǒng)的研究主要分為場(chǎng)景、人物模型搭建,人物動(dòng)作制作以及漫游系統(tǒng)編寫(xiě)。本文通過(guò)查閱國(guó)內(nèi)外文獻(xiàn),研究學(xué)習(xí)了場(chǎng)景建模、動(dòng)作控制以及虛擬漫游等相關(guān)算法和技術(shù)。場(chǎng)景模型和角色模型是對(duì)現(xiàn)實(shí)世界的模擬,其真實(shí)程度直接影響了用戶(hù)的感官體驗(yàn)。運(yùn)動(dòng)控制和交互功能提升了用戶(hù)的參與度,增強(qiáng)了漫游系統(tǒng)的沉浸感。在研究虛擬場(chǎng)景漫游技術(shù)中,本文主要研究和實(shí)現(xiàn)了以下內(nèi)容：(1)以Quest3D軟件為虛擬場(chǎng)景漫游開(kāi)發(fā)平臺(tái),研究了多邊形和曲面建模技術(shù)并與紋理映射算法相結(jié)合構(gòu)建了具有真實(shí)感的虛擬場(chǎng)景和角色模型；(2)分析了關(guān)節(jié)動(dòng)畫(huà)算法、漸變動(dòng)畫(huà)算法和骨骼蒙皮動(dòng)畫(huà)算法,利用骨骼蒙皮技術(shù)和關(guān)鍵幀技術(shù)制作了虛擬角色的交互動(dòng)作；(3)應(yīng)用了Quest3D獨(dú)特的元件編程方法,實(shí)現(xiàn)了虛擬角色的動(dòng)作控制、視角切換以及自動(dòng)感應(yīng)噴泉等交互功能；(4)通過(guò)系統(tǒng)發(fā)布,完成了具有虛擬角色的場(chǎng)景漫游系統(tǒng)。虛擬場(chǎng)景漫游系統(tǒng)的開(kāi)發(fā)和實(shí)現(xiàn)讓用戶(hù)欣賞了虛擬場(chǎng)景中宏偉的建筑和美麗的自然風(fēng)光,同時(shí)虛擬角色的引入更提升了用戶(hù)的參與度,增強(qiáng)了虛擬漫游系統(tǒng)的真實(shí)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.
