In this piece of work, we seek to control digital characters in real-time.

在这篇论文里，我们探索了如何实时控制虚拟人物。

It takes virtual digital characters and overlays them onto scenes from the real world.

它将虚拟数字角色叠加到现实世界的场景中。

Studying hours of reference footage to create the digital characters also help them imitate weightlessness more accurately.

剧组会事先研究数小时的参考镜头来创建虚拟角色，以帮助演员更准确地模仿失重。

This was great for animating digital characters when all we have is sound.

这对于制作虚拟人物动画非常棒，因为我们已有的仅仅是声音。

And then that sound clip can be used with this technique to make a digital character say what we've written.

然后这个技术就可以用此声音片段来生成一个虚拟人物来说我们写下的话。

This means that not only the changes in the facial geometry are transferred to a digital character, no, no, no.

这意味着不仅仅要将面部几何的变化转移成数字字符，是的，不只是这样。

Pokemon Go is one example of augmented reality. It takes virtual digital characters and overlays them onto scenes from the real world.

《宝可梦GO》是一款增强现实游戏。它将虚拟数字角色叠加到现实世界的场景中。

Then later when the animators go to animate the digital character, they kind of tell the computer what expression the actor wants to be in.

之后，当动画师制作数字角色的动画时，他们会告诉电脑演员想要什么表情。

And today, we're going to talk about a technique that is able to create these highly detailed cloth geometries for our digital characters.

今天，为了我们的数字化人物 我们将介绍一种，为这种高细节布料创建出几何形状的技术。

Inside the world's oldest working film studio, a new generation of digital characters like this guy are coming to life.

在世界上最古老的电影制片厂内，像这个人这样的新一代数字角色正在栩栩如生。

And this time, we're interested in controlling the joints of a digital character to not only walk properly, but take into consideration its surroundings.

今天，我们感兴趣的是如何控制虚拟人物的关节，从而使它不仅能正确地行走，还能考虑到周围的环境而运作。

It could be a digital character or a hologram; it could be new kitchen appliances in the empty space of an unfinished house.

它可以是数字字符或全息图；它可能是未完工房屋空置空间中的新厨房用具。

This means that after recording the audio footage of us speaking, we give it to a learning algorithm, which creates a high-quality animation depicting our digital characters uttering these words.

这意味着录制完我们说话的音频视频之后，我们把数据给一个学习算法，它就能够生成高质量的动画来描绘说这些话的虚拟人物。

This is different from what we've seen a few episodes ago, where scientists at NVIDIA worked on synthesizing lip sync geometry for digital characters solely relying on audio footage.

与之不同的是，我们之前曾讲过在 NVIDIA 工作的科学家们致力于只依靠音频脚本合成虚拟人物的唇型、使其与音频同步的研究。

The animation step takes the information of how the desired target expressions evolve in time, and some physics information, such as gravity or wind, and the forward physics unit computes the final simulation of the digital character.

通过动画过程获取到所期望的表达对象适时演变的信息以及一些物理信息，例如重力或风力和前沿物理单元计算的终极仿真数字字符。
