The Kinect's role is crucial. Once researchers have put the object in the gripper, it measures its exact position and orientation in relation to where the 3D film will be placed. It's not until that information has been collected that the researchers can print the film on a standard inkjet printer, which will then include the necessary image deformations and account for the image stretch that will occur during the dip — ones that will make the final melded object look just right.

　　Kinect的角色至关重要。当研究者把扫描对象放在爪子中，根据三维胶片的位置，装置就可以测量扫描对象的确切位置和方向。直到信息搜集完毕，研究者才能把胶片放在一个标准的喷墨打印机上，用以处理图像变形以供在浸入时的图像拉伸。

　　In a video announcing the breakthrough, the Zhejiang University and Columbia University teams show off a printed tiger mask, zebra, single dip-globe and a 3D-printed cat. For the cat, the team performed three dips to wrap the initially monochrome kitten in a photo-realistic skin. The result has that uncanny valley problem of looking almost real, but not quite.

　　在一段宣布这项突破的视频中，浙江大学和哥伦比亚的研究团队展示了老虎面具，斑马，猫等成品。关于这只猫，研究团队演示了三次浸入的方法，把原来单色的小猫包裹上了极具真实感的皮肤。最终的效果看起来可以乱真，但是并不完美。

　　There are some limitations. Researchers note that they cannot easily cover objects featuring highly concave surfaces or any surface that might be hidden from view or scanning. Color blending and precision is also a bit of a challenge, and when the film stretches out significantly, some color can become lighter than the original color.

　　当然也存在一些局限，研究者表示，他们不能很轻易给有巨大凹面或者扫描不到的地方着色。颜色的混合和精度也是一项挑战，当胶片被拉伸过度的时候，有一些颜色也要比原色更浅一些。

　　Even with those limitations, this relatively simple method for adding complex patterns and photo-real imagery to monochromatic 3D-printed objects shows promise. One can imagine someone scanning and printing a lifelike 3D model of a person's head, then using a high-res photograph to print out a face and sides, top and back of the head. Multiple computationally guided dips would then create a truly scary bust.

　　尽管有着各种局限，但是对于把复杂图案和现实照片加到单色三维物体，这种方法还是很有前景的。我们可以想象：当你扫描并且打印了一个人的三维头部模型，然后把高分辨率的照片印到脸部和侧面，还有顶部和后部。通过多次计算机导航浸入印刷可以制作出一个真正让人惊悚的东西。
