Imagine a camera that could take photographs that looked like paintings. Some modern video cameras already allow this - I have such a camera. The software built into it traces over photographs to yield painterly effects that look like an oil painting, or a watercolour, or any of the many media available to commerical systems.But now, instead of just tracing, imagine a camera that is able to rotate objects so they are painted from new points of view, and even render different parts of the same object from different points of view. This camera can enhance the three-dimensional nature of objects by making marks that line-up with curves on it, and can even enhance prominent features by making them bigger still. And more, this camera works not just on still images but on moving images too, enabling cartoon-like effects - cartoon cars that really burn the road!This 3D-painting camera would allow you to snap your own old Masters, such as Van Eyck, who deliberately broke the rules of perspective to draw attention to what was going on in his pictures. Newer Masters like Matisse who liked to tilt and twist the objects as he painted them; and yet newer Masters like Hockney who has made a recent habit of painting by compositing photographs taken from different views. It would allow you to really bring out the shape of an object, shading it the way Durer once did. And it would allow you to create your own cartoons, complete with streak-lines, squash-and-stretch effects and dust-clouds, all in three-dimensions for the first time.Our research is about building such a camera.

想象一下可以拍摄看起来像绘画的照片的相机。一些现代摄像机已经允许 - 我有这样的相机。它内置的软件可以追踪照片，以产生看起来像油漆，水彩或可用于商业系统的众多媒体中的任何绘画作用。但是现在，不仅仅是追踪，还可以想象一个摄像机可以旋转物体，从而从新的角度绘制它们，甚至从相同的对象的不同部分中绘制它们。该摄像机可以通过在其上与曲线进行刻度来增强对象的三维性质，甚至可以通过使它们更大的速度来增强突出的功能。更重要的是，这款相机不仅可以在静止图像上，还可以在移动的图像上使用，从而实现了像卡通般的效果 - 真正燃烧道路的卡通汽车！这款3D绘制的摄像头可以使您能够抢购自己的旧大师，例如van eyck，他们故意打破了观点规则，以吸引他的照片中的观点。像马蒂斯（Matisse）这样的较新大师，他喜欢在绘画时倾斜和扭动物体。然而，像霍克尼（Hockney）这样的新大师曾通过从不同观点拍摄的照片养成了最近绘画的习惯。它可以让您真正带出对象的形状，以持续时间曾经的方式遮盖它。它可以让您创建自己的动画片，并配有条纹线，南瓜和拉伸效果和灰尘云，所有这些都是第一次以三维为单位。我们的研究是关于构建这样的相机。
