我们提出了一种允许非熟练用户创建数字3D模型准确的物理副本的方法。我们使用投影仪/摄像头对扫描正在进行的工作，并将多种形式的指导投影到对象本身上，以指示哪些区域需要更多的材料，需要更少的材料以及任何山脊，山谷或深度不连续性。用户使用指导和迭代来调整模型，从而使目标3D模型随着时间的推移形成。我们展示了如何使用这种方法来创建现有对象的副本，通过扫描对象并将扫描作为目标形状来创建现有对象的副本。用户可以自由地以不同的规模和不同的材料进行复制：我们将玩具车变成蛋糕。我们扩展了该技术，以支持复制一系列模型以创建定格视频。我们演示了一个端到端系统，其中将实际性能捕获数据重新定位为粘土化。我们的方法使用户可以轻松，准确地创建复杂的形状，并且自然支持各种材料和模型尺寸。
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.
