【摘要】： 近年來(lái),由于計(jì)算機(jī)技術(shù)的發(fā)展,動(dòng)漫行業(yè)產(chǎn)生了巨大的革新,并提出了新的技術(shù)要求。本課題——廣東省科技廳項(xiàng)目,數(shù)字媒體創(chuàng)意支持平臺(tái)擬在網(wǎng)絡(luò)上建立大型渲染平臺(tái)。由于動(dòng)漫行業(yè)為追求真實(shí)性和視覺效果,大量使用高質(zhì)量的三維技術(shù)。本子系統(tǒng)在負(fù)責(zé)在B/S環(huán)境中以Web3D插件的形式,擴(kuò)充現(xiàn)有瀏覽器,在WebKit的瀏覽器引擎上實(shí)現(xiàn)三維渲染插件。并通過插件的可變編程腳本語(yǔ)言接口,和對(duì)數(shù)據(jù)交換協(xié)議的支持輔助動(dòng)漫,尤其是三維動(dòng)漫從業(yè)人員。 本文研究了針對(duì)動(dòng)漫行業(yè)的瀏覽器三維渲染插件的實(shí)現(xiàn)方法,并設(shè)計(jì)了原形程序。本文利用Web3D的標(biāo)準(zhǔn)語(yǔ)言X3D作為為數(shù)據(jù)傳輸格式, OpenGL作為底層渲染庫(kù)。首先分析了以上數(shù)據(jù)傳輸標(biāo)準(zhǔn)和瀏覽器環(huán)境的實(shí)際情況,整理分類出X3D的節(jié)點(diǎn)。然后研究并實(shí)現(xiàn)了在WebKit瀏覽器框架上以插件形式將X3D數(shù)據(jù)在渲染成三維圖型的一種方案。在此基礎(chǔ)上參考了三維渲染引擎的設(shè)計(jì)模式并架構(gòu)了以場(chǎng)景管理器為核心的渲染系統(tǒng)。系統(tǒng)優(yōu)化了針對(duì)瀏覽器環(huán)境和XML解析的場(chǎng)景管理器、作為核心的動(dòng)態(tài)樹算法、規(guī)則;并設(shè)計(jì)了一套靈活的渲染對(duì)象組織方案:將紋理、光照材質(zhì)、和顏色渲染對(duì)象進(jìn)行區(qū)分——基于這個(gè)事實(shí):沒有人會(huì)希望在離散點(diǎn)上貼圖。本次研究在設(shè)計(jì)思路上借鑒并有針對(duì)性地改變了,如工場(chǎng)模式渲染對(duì)象接口,場(chǎng)景管理樹等渲染引擎設(shè)計(jì)等方法。最后對(duì)工作出了總結(jié)和并展望了行業(yè)前景,同時(shí)提出了針對(duì)現(xiàn)今狀況Web3D客戶端今后的研究方向。 本課題對(duì)于現(xiàn)今的B/S客戶端研究來(lái)說是一種革新性的嘗試,從動(dòng)漫入手為未來(lái)的網(wǎng)絡(luò)展示形式做出了探索性的工作。
[Abstract]:In recent years, because of the development of computer technology, animation industry has produced tremendous innovation, and put forward new technical requirements. This topic-Guangdong Province Science and Technology Department project, digital media creative support platform to build a large-scale rendering platform on the network. Animation industry for the pursuit of authenticity and visual effects, the use of high-quality 3D technology. This subsystem is responsible for extending the existing browser in the form of Web3D plug-in the B / S environment and implementing the 3D rendering plug-in on the browser engine of WebKit. And through the plug-in variable programming script language interface, and data exchange protocol support to assist animation, especially 3D animation practitioners. In this paper, the implementation method of browser 3D rendering plug-in for animation industry is studied, and the prototype program is designed. In this paper, Web3D's standard language X3D is used as the data transfer format, and OpenGL is used as the underlying rendering library. Firstly, the data transmission standard and the actual situation of browser environment are analyzed, and the nodes of X3D are sorted out. Then, a scheme of rendering X3D data into 3D graphics in the form of plug-in on the framework of WebKit browser is studied and implemented. On this basis, the design pattern of 3D rendering engine is referred to and the rendering system with scene manager as the core is constructed. The system optimizes the scene manager for browser environment and XML parsing, as the core of the dynamic tree algorithm, rules, and designs a flexible rendering object organization scheme: texture, lighting material, Distinguish from color rendering objects-based on the fact that no one wants to map on discrete points. In this study, the design ideas have been changed, such as workshop mode rendering object interface, scene management tree and other rendering engine design methods. Finally, the paper summarizes the work and looks forward to the future of the industry. At the same time, the future research direction of Web3D client is put forward. This paper is an innovative attempt for the current research of B / S client. It makes an exploratory work for the future network display form from the animation.
