摘要

我们提出了一套完整的平面截面结构创作系统,它在艺术和工程中都很常见。对平面截面组合体的想象和绘制的研究指导了我们的设计原则:平面截面最好在现场绘制,少缩短,与相交的平面截面正交,显示平面和轮廓之间的规律性。我们通过新颖的绘图工作流程捕获这些原则,其中单个流体用户笔画指定3D平面及其与现有平面部分相关的轮廓。通过定义平面相交部分的程序操作词汇表来支持规则性。我们利用平面结构的特性来提供物理模拟应力的实时视觉反馈,以及结构稳定、连接和可组装的几何验证。该反馈通过真实世界的制造和测试得到验证。作为评估,我们报告了50多名受试者,他们都使用我们的系统,以最少的指导来创建独特的模型。

FlatFitFab: interactive modeling with planar sections
We present a comprehensive system to author planar section structures, common in art and engineering. A study on how planar section assemblies are imagined and drawn guide our design principles: planar sections are best drawn in-situ, with little foreshortening, orthogonal to intersecting planar sections, exhibiting regularities between planes and contours. We capture these principles with a novel drawing workflow where a single fluid user stroke specifies a 3D plane and its contour in relation to existing planar sections. Regularity is supported by defining a vocabulary of procedural operations for intersecting planar sections. We exploit planar structure properties to provide real-time visual feedback on physically simulated stresses, and geometric verification that the structure is stable, connected and can be assembled. This feedback is validated by real-world fabrication and testing. As evaluation, we report on over 50 subjects who all used our system with minimal instruction to create unique models.
