SGER: Exploratory Research in Sketch-Based Modeling

SGER：基于草图的建模探索性研究本研究探索了一种通过放大传统的纸上草图来设计3D形式的新范式。早期的工作表明，3D设计和分析可以只使用附加在2D平面上的笔画并放置在3D空间中。当用户从不同的角度观察时，就会出现明显的形式。这项研究将通过增加草图搜索和探索来扩展早期的工作。这项工作是在一个完整的建筑设计系统的背景下进行的，从概念草图到实体模型。这项工作通过提供一种创建和编辑3D形式的新方法来推进创造性设计过程，并将影响2D表示在很大程度上占主导地位的思想交流。这项工作不仅涉及计算机图形学和建筑学，还涉及与人类如何思考（如计算机视觉、认知科学、心理学）和建造（工业设计、土木工程、机械工程）相关的其他研究领域。随着万维网的扩展和b谷歌等公司的成功，搜索已成为一个活跃的研究领域，开发了从文本到3D对象的搜索方法。然而，关于搜索和操纵草图的工作很少，如果没有的话。在本研究中，考虑了两种方法：基于谱图的方法和球面谐波的表示。还考虑了用于探索时间草图演变和草图之间导航关系的工具。可视化界面用于形成草图查询。

SGER: Exploratory Research in Sketch-Based ModelingThis research explores a new paradigm for designing 3D form by amplifying traditional sketching on paper. Early work has shown that 3D design and analysis can be performed using only strokes attached to 2D planes and placed in 3D space. Apparent form emerges as the user observes from different views. This research will expand early work by adding sketch search and exploration. This work is examined in the context of a complete system for architectural design that moves from conceptual sketching to solid models. The work advances the creative design process by offering a novel approach for creating and editing 3D form, and will also impact the communication of ideas, where 2D representation has largely dominated. This work crosses and links disciplines, not only computer graphics and architecture, but other research areas related to how humans think (such as computer vision, cognitive science, psychology) and build (industrial design, civil engineering, mechanical engineering). With the expansion of the World Wide Web and success of companies, such as Google, search has become an active area of research, with methods developed for searching for items from text to 3D objects. Yet little, if no, work has addressed searching and manipulating sketches. In this research, two approaches are considered: spectrum-graph-based methods and representations in terms of spherical harmonics. Tools for exploring temporal sketch evolution and navigating relationships between sketches are also considered. A visual interface is used for forming sketch queries.
