我们描述了一种新技术，该技术通过一组概念草图来支持产品的探索和工程。我们的方法允许捕获和重用概念草图中包含的几何形状信息，作为生成同时满足美学和功能要求的解决方案的一种手段。我们方法的核心是基于图形的草图表示，它允许确定输入草图中的拓扑和几何相似性。该分析与几何变形分析相结合，产生一个设计空间，可以从中合成新的形状，或者可以优化开发设计以满足规定的目标。此外，它还有助于对现有设计进行基于草图的交互式编辑，从而保留在设计空间中捕获的形状特征。该方法的一个关键优点是，可以单独识别所有草图共有的形状特征以及每个草图独有的形状特征，从而允许混合不同的草图以生成拓扑和几何上丰富的概念替代集。我们通过 2D 和 3D 示例演示我们的技术。
We describe a new technique that works from a set of concept sketches to support the exploration and engineering of products. Our approach allows the capture and reuse of geometric shape information contained in concept sketches, as a means to generate solutions that can concurrently satisfy aesthetic and functional requirements. At the heart of our approach is a graph-based representation of sketches that allows the determination of topological and geometric similarities in the input sketches. This analysis, when combined with a geometric deformation analysis, results in a design space from which new shapes can be synthesized, or a developing design can be optimized to satisfy prescribed objectives. Moreover, it facilitates a sketch-based, interactive editing of existing designs that preserves the shape characteristics captured in the design space. A key advantage of the proposed method is that shape features common to all sketches as well as those unique to each sketch can be separately identified, thus allowing a mixing of different sketches to generate a topologically and geometrically rich set of conceptual alternatives. We demonstrate our technique with 2D and 3D examples.
