低成本制造机器（例如，3D打印机）提供了由一系列用户创建定制设计对象的承诺。为了最大限度地提高性能，拓扑优化等生成式设计方法可以根据高级规范自动优化设计的属性。虽然很有前途，但这种方法需要人们将他们的设计想法（通常是不直观的）映射到少量的数学输入参数，并且这些参数与生成的设计之间的关系通常是不清楚的，这使得很难对设计进行分析。我们提出了Forte，一个基于草图的实时交互式工具，让人们通过2D拓扑优化直接表达和展示他们的设计。用户可以要求系统添加结构，提供具有更好性能的变体，或优化内部材料布局。用户可以全局控制从初始草图“偏离”多少，或者执行局部提示性编辑，这会交互地提示系统根据新信息进行更新。有10名参与者的设计会议表明，Forte使设计师能够创建和探索一系列具有自定义形式和风格的优化设计。
Low-cost fabrication machines (e.g., 3D printers) offer the promise of creating custom-designed objects by a range of users. To maximize performance, generative design methods such as topology optimization can automatically optimize properties of a design based on high-level specifications. Though promising, such methods require people to map their design ideas--often unintuitively--to a small number of mathematical input parameters, and the relationship between those parameters and a generated design is often unclear, making it difficult to iterate a design. We present Forte, a sketch-based, real-time interactive tool for people to directly express and iterate on their designs via 2D topology optimization. Users can ask the system to add structures, provide a variation with better performance, or optimize internal material layouts. Users can globally control how much to 'deviate' from the initial sketch, or perform local suggestive editing, which interactively prompts the system to update based on the new information. Design sessions with 10 participants demonstrate that Forte empowers designers to create and explore a range of optimized designs with custom forms and styles.
