SGER: Exploratory Research in Sketch-Based Modeling

SGER：基于草图的造型的探索性研究本研究通过在纸上放大传统的草图，探索了一种新的设计3D形式的范式。早期的工作表明，只需将笔划附加到2D平面并放置在3D空间中，就可以进行3D设计和分析。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工作。这项工作是在一个从概念草图到实体模型的完整建筑设计系统的背景下进行研究的。这项工作通过提供一种创建和编辑3D形状的新方法来推进创造性设计过程，并将影响思想的交流，其中2D表示在很大程度上占主导地位。这项工作跨越和联系了多个学科，不仅是计算机图形学和建筑学，而且还有其他与人类思维方式(如计算机视觉、认知科学、心理学)和建筑(工业设计、土木工程、机械工程)相关的研究领域。随着万维网的扩张和谷歌等公司的成功，搜索已成为一个活跃的研究领域，开发了从文本到3D对象的搜索项目的方法。然而，几乎没有什么工作涉及到搜索和操纵草图。在这项研究中，考虑了两种方法：基于谱图的方法和球谐表示法。还考虑了用于探索时态草图演化和草图之间导航关系的工具。可视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.
