从3D网格创建物理支架是一个独特的渲染挑战，以前还没有解决。该任务是两个相互竞争的目标的问题：形成一个单一的，良好连接和稳定的模板，同时限制由桥接材料片引入的错误。在这些相互冲突的目标下，通常很难用手工从复杂的图像中创建视觉上令人愉悦的效果。即使对于行为良好的图像，手动制作表达性的支架也可能非常耗时。
我们提出了一种方法，从多边形网格或图像生成表达的stentums。在我们的系统中，用户提供输入的几何形状，并可以调整所需的视图，照明条件，线的厚度和桥梁的喜好，以实现他们最终所需的模板。模板创建算法使用多个度量来测量不稳定模板区域之间的连接的适当性。这些指标描述了局部特征，以帮助最大限度地减少因稳定桥梁而导致的抽象图像失真。该算法还使用局部统计来选择最佳拟合连接，该连接既保持结构完整性又保持局部形状信息。我们证明了我们的算法的物理介质，包括建筑纸和金属板。
Creating physical stencils from 3D meshes is a unique rendering challenge that has not been previously addressed. The task is a problem of two competing goals: forming a single, well-connected and stable stencil sheet, while simultaneously limiting the error introduced by pieces of bridging material. Under these conflicting goals, it can often be difficult to create visually pleasing stencils from complicated imagery by hand. Even for well-behaved images, expressive stencils can be time-consuming to craft manually.
We present a method for generating expressive stencils from polygonal meshes or images. In our system, users provide input geometry and can adjust desired view, lighting conditions, line thickness, and bridge preferences to achieve their final desired stencil. The stencil creation algorithm makes use of multiple metrics to measure the appropriateness of connections between unstable stencil regions. These metrics describe local features to help minimize the distortion of the abstracted image caused by stabilizing bridges. The algorithm also uses local statistics to choose a best fit connection that maintains both structural integrity and local shape information. We demonstrate our algorithm on physical media including construction paper and sheet metal.
