Alec Rivers, Andrew Adams, Frédo Durand 摘要：我们提出了一个方法，可以让一个不熟练的用户创建一个准确的数字化三维牙颌模型的物理副本。我们使用投影机/相机对扫描到对象本身，表明哪些领域需要更多的材料，需要较少的工作正在进行中，项目多形式的指导，山脊，山谷或深度不连续的地方。用户调节的模型中使用的指导和迭代点，使得物理对象的方法，随着时间的推移的目标的三维模型的形状。我们表明，这种方法可以用来创建一个重复的现有对象，通过扫描对象为目标的形状和使用的扫描。用户可以自由复制在不同的规模和不同的材料：我们的玩具车蛋糕。我们延长的技术支持复制的模型来创建停止运动的视频序列。我们展示一个终端到终端的系统中，现实世界中的表现捕获的数据重定向到黏土动画。我们的方法使用户能方便，准确地创建复杂的形状，自然地支持了大范围的材料和模型的大小。Abstract：We propose a method that allows an unskilled user to create an accurate physical replica of a digital 3D model. We use a projector/camera pair to scan a work in progress, and project multiple forms of guidance onto the object itself that indicate which areas need more material, which need less, and where any ridges, valleys or depth discontinuities are. The user adjusts the model using the guidance and iterates, making the shape of the physical object approach that of the target 3D model over time. We show how this approach can be used to create a duplicate of an existing object, by scanning the object and using that scan as the target shape. The user is free to make the reproduction at a different scale and out of different materials: we turn a toy car into cake. We extend the technique to support replicating a sequence of models to create stop-motion video. We demonstrate an end-to-end system in which real-world performance capture data is retargeted to claymation. Our approach allows users to easily and accurately create complex shapes, and naturally supports a large range of materials and model sizes.
