title	Navigation In 3D Information Landscape-A 3D Museum for Civic Buildings
source	CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 641-650

summary	Navigation is about information that requires visual feedback and spatial orientation in both information representation and userinteraction. Among those, spatial orientation is the primary research question for navigating in 3D information landscape. By inspired by Ware's three control loops, 'spatial metaphors' and 'visual components" are proposed as the fundamental concepts of a navigation framework called 'i-Room'. i-Room is comprised of four constituents-handles, i-Bag, i-Map and Focus/scale. An information landscape based on a repository of diverse digital media of 11 significant civic buildings in Taiwan is designed for testing this navigation framework. An implementation of i-Room based on Muse of navigation realization and their interaction behaviors with spatial metaphors/visual components is also reported in this paper.

title	Companying Physical Space With Virtual Space A Co-Existence Approach
source	CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 359-370
doi	https://doi.org/10.52842/conf.caadria.2003.359
summary	This paper presents a kind of co-existence relationship: companying physical space with virtual space with a case study. The fundamental approach is to investigate the interactive relationship between navigators and information in virtual space, including collecting, interpreting, integrating, and communicating. Based on these relationships, we propose an information structure, which elaborates the information of our co-existence representation. The infrastructure composed with two processes of data representation based on an individual spatial structure is tested in representing eleven historical significant civic building in Taiwan.

title	Dynamic Interactions Between Users and Information in a Co-existence Space
source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 58-65
doi	https://doi.org/10.52842/conf.ecaade.2004.058
summary	By exploring interactions between users and information, this paper intends to propose a co-existence framework for companying physical space with virtual space. Based on this framework, we implement an information structure for users to interact with information space interactively, which includes information nodes, hyperlinks and interplays through i-Room system (Chang and Lai, 2003). Furthermore, the information structure of representation is also tested and reevaluated in representing ten historical significant civic buildings in Taiwan.

title	Ivy: Bringing a Weighted-Mesh Representations to Bear on Generative Architectural Design Applications

summary	Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.
