　　Nothing says "the future" like a disembodied head. As developers and designers begin churning out the next generation of games and entertainment, the pace of technology demos showing what types of computer-generated graphics will soon be possible has picked up. And that means one thing: more creepy-yet-astonishing 3D-generated heads.

　　沒有什么能比一顆活生生的頭部更能代言“未來”。隨著開發(fā)及設計人員紛紛著手研發(fā)下一代的游戲娛樂系統(tǒng)，這項預示著最新計算機生成圖像效果的技術已經取得了進展。而這意味著一件事——我們將看到更多令人毛骨悚然、卻又不由驚嘆的3D合成頭像。

　　Activision (ATVI) is showing off new technology at the annual Game Developer's Conference, taking place in San Francisco this week. The rendering techniques and code that create life-like animation were unveiled by the gaming giant's research and development division yesterday. The animated character shown here is being rendered in real-time on current video card hardware, suggesting innovations like these could be showing up in commercial products sooner rather than later.

　　美國動視(Activision)在上周于舊金山舉辦的一年一度的游戲開發(fā)者大會(Game Developer's Conference)上展示了他們的最新技術成果。這家游戲開發(fā)巨頭的研發(fā)部門昨天發(fā)布了可以生成的渲染技術及代碼。此處所示的動態(tài)人物是在顯卡設備上實時渲染而成的。它意味著類似的創(chuàng)新技術要不了多久就會出現在各類商業(yè)性產品上。

　　"We will show how each detail is the secret for achieving reality," wrote researcher Jorge Jimenez on his blog, before the presentation. "For us, the challenge goes beyond entertaining; it's more about creating a medium for better expressing emotions and reaching the feelings of the players. We believe this technology will bring current generation characters, into next generation life."

　　“我們將讓大家看到，每一處細節(jié)才是表現真實感的秘訣?！贝髸菔局?，研究人員喬治?吉梅內茲在自己的博客上寫道：“對我們來說，這場挑戰(zhàn)面向的不僅僅是娛樂應用，更多的是要打造一種媒介，能夠更好地表現情緒、引發(fā)玩家共鳴。我們相信，這項技術能夠為現世代的游戲角色注入次世代的生命?！?/p>

　　Activision isn't alone. Chipmaker NVIDIA (NVDA) recently touted real-time face-rendering at its GPU Technology Conference in California. The program, dubbed Face Works, employs face- and motion-capture technology developed at the University of Southern California's Institute of Creative Technology. The center's Light Stage process records data to within a tenth of a millimeter using photography that captures the geometry of an actor's face. Light transmission through skin -- the key to rendering subtle emotional cues like blushing -- and reflections can be recreated as well.

　　抱著這種想法的開發(fā)商并非僅只動視一家。芯片制造商英偉達(NVIDIA)最近在該公司于加利福尼亞召開的GPU技術大會(GPU Technology Conference)上大力鼓吹實時面部渲染技術。這套名為“面子工程”(Face Works)的程序采用了美國南加州大學
