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，一台相机可以拍出像绘画一样的照片。一些现代摄像机已经允许这样做了——我有一个这样的摄像机。内置的软件可以对照片进行跟踪，从而产生像油画、水彩画或商业系统中可用的任何一种媒体一样的绘画效果。但是现在，不仅仅是追踪，想象一下一个能够旋转物体的相机，这样就可以从新的角度绘制物体，甚至可以从不同的角度渲染同一物体的不同部分。这款相机可以通过在物体上制作与曲线对齐的标记来增强物体的三维特性，甚至可以通过将突出的特征变得更大来增强它们。更重要的是，这款相机不仅可以拍摄静止图像，还可以拍摄运动图像，从而实现卡通效果——卡通汽车真的可以燃烧道路！这款3d绘画相机可以让你拍摄自己的老大师，比如凡·艾克，他故意打破透视规则，把注意力吸引到他的画中发生的事情上。马蒂斯（Matisse）等新晋大师在绘画时喜欢倾斜和扭曲物体；还有像霍克尼这样的新大师，他最近养成了从不同角度合成照片的习惯。它可以让你真正地呈现出物体的形状，像丢勒曾经做过的那样给它涂上阴影。它将允许你创建自己的卡通，包括条纹，挤压和拉伸效果和尘埃云，所有这些都是第一次在三维空间中完成的。我们的研究就是要制造这样一个相机。
