　　精品阅读：你看你看, 未来的"脸"

　　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.

　　没有什么能比一颗活生生的头部更能代言“未来”。随着开发及设计人员纷纷着手研发下一代的游戏娱乐系统，这项预示着最新计算机生成图像效果的技术已经取得了进展。而这意味着一件事——我们将看到更多令人毛骨悚然、却又不由惊叹的3D合成头像。

　　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.

　　美国动视(Activision)在上周于旧金山举办的一年一度的游戏开发者大会(Game Developer's Conference)上展示了他们的最新技术成果。这家游戏开发巨头的研发部门昨天发布了可以生成的渲染技术及代码。此处所示的动态人物是在显卡设备上实时渲染而成的。它意味着类似的创新技术要不了多久就会出现在各类商业性产品上。

　　"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."

　　“我们将让大家看到，每一处细节才是表现真实感的秘诀。”大会演示之前，研究人员乔治?吉梅内兹在自己的博客上写道：“对我们来说，这场挑战面向的不仅仅是娱乐应用，更多的是要打造一种媒介，能够更好地表现情绪、引发玩家共鸣。我们相信，这项技术能够为现世代的游戏角色注入次世代的生命。”

　　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.

　　抱着这种想法的开发商并非仅只动视一家。芯片制造商英伟达(NVIDIA)最近在该公司于加利福尼亚召开的GPU技术大会(GPU Technology Conference)上大力鼓吹实时面部渲染技术。这套名为“面子工程”(Face Works)的程序采用了美国南加州大学
