title A Configuration-Generating Method Based on a Lattice System
source CAADRIA ‘96 [Proceedings of The First Conference on Computer Aided Architectural Design Research in Asia / ISBN 9627-75-703-9] Hong Kong (Hong Kong) 25-27 April 1996, pp. 199-215
summary In this paper, I would propose a configuration-generating method: "L grammars”. Relating to Turing machine, cellular automata, tiling problem and Wang tile theory. It is named Lgrammars”. L grammars base on an infinite lattice space (usually a chess-board-like lattice plane) is a bottom-up approach, in which each cell of a lattice system corresponds to a bounded configuration unit. Thus, a lattice plane would corresponds to a configuration union. The power of L grammars is demonstrated by generating various configurations such as fractal images (two dimensional examples) and crystal models (three dimensional examples). Finally, it would be discussed briefly about some interesting issues concerning about L grammars such as the limitations of L grammars.

title Design with bamboo bend: Bridging natural material and computational design
source Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 125-133
summary Bamboo is a high potential alternative solution for substi- tuting industrial material with its natural characteristics, economical and environmental aspects. However, one of the biggest challenges for natural materials to be used in computational designed is the control- lability due to its unevenness nature. The other gap is the lack of ma- terial parameters that might be bridged by analysing data acquired from conventional tests. This research studied the raw bamboo strip and its natural forming from bending, by using sampling points and curvature reconstruction. The parametric models of bamboo strips were then constructed to represent its material behaviours for form prediction, material selection, and simulation in parametric design. It also serves as an assistive method for material selection when crafting with bamboo bend.

summary Beaver dams are formed by two main processes. One is that beavers select proper woods for constructing. The other one is that streams aggregate those woods to be assembled. Using this approach to construction structure is suitable for natural environment. In this paper, we attempt to develop a construction process which is suitable for all-terrain construction robot in the future. This construction process is inspired by beavers' construction behavior in nature. Beavers select proper sticks to make the structure stable. We predict that particular properties of sticks contribute gravity-driven assembly of wood structure. Thus, we implement the system with machine learning to find proper properties of sticks to improve selection mechanism of construction process. During this construction process, 3D scanner on robotic arm scans and recognizes sticks on terrain, and then robot will select proper sticks and place them. After placement, the system will scan and record the results for learning mechanism.

summary In this research, we attempt to develop a tool which integrates certain common geographic information from OpenStreetMap and OpenTopography into Grasshopper. We name it as OSMKIT temporarily. Besides, in order to make the integration in the design process easier, this tool includes the bilateral conversion function of coordinate in Rhinoceros 3D and the coordinate of the World Geodetic System. These characteristics bring about several possibilities for further usage. This paper contains explanations of functions and examples. For instance, it can be employed for data visualization on a map when these data contain coordinate information. Additionally, since this tool is simple and intuitive to convert points into GPS coordinates, it can make users plan drone for photogrammetry and deal with other related tasks on the rhinoceros 3D interface, helping them to gain most current urban models. Moreover, architects or designers can be not only users but also contributors for open source map system such as OpenStreetMap; the process of sharing the mode which user measure is demonstrated in this paper. To sum up, this coordinate system based tool is designed to be multifunctional and suitable for interdisciplinary usages in grasshopper.

title Robotic Glass Crafting by Dip Forming

summary This research is to develop a robotic glass crafting dip-forming process by dip forming. Instead of employing molds, we utilize repetitive dip coating and gravity to shape the glass. In addition, its morphogenesis process is similar to the certain growth mechanisms in nature, such as geotropism and branching. During the forming process, melted glass is accumulated layer by layer gradually until the target geometry is completed. The process takes advantage of the precision of the industrial robotic arm and the viscosity property of the material. This process requires the custom-made tool to operate in high temperature and controlling the timing of heating and annealing to eliminate Z artifacts caused by layered deposition, achieving the crystal-clear effect of the glass craft without the post cure process after printing. In addition, the robotic arm provides a higher degree of freedom for forming. This research demonstrates glassworks in the organic form including variations in thickness and branching to test the proposed method.

summary This paper proposes a method of mesh simplification for 3D terrain or city models generated photogrammetrically from drone captured images, enabled by the ability of extracting the architectural features. Compare to traditional geometric computational method, the proposed method recognizes and processes the features from the architectural perspectives. In addition, the workflow also allows exporting the simplified models and geometric features to open platforms, e.g. OpenStreetMap, for practical usages in site analysis, city generation, and contributing to the open data communities.

title NEW MEDIA IN DIGITAL DESIGN PROCESS: Towards a standardize procedure of CAD/CAM fabrication
source CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 597-599
summary In 1990, due to the traditional architecture design and construction method difficult to build the complicated and non-geometry free-form Fish Structure in Barcelona, architect Frank Gehry started learn from the field of aerospace to utilize CAD/CAM technology in design and manufacture process. He created the free-form fish model in CAD system and exported the digital CAD model data to CAM machine (RP and CNC) to fabricate the design components, and finally assembled on the site. Gehry pioneered in the new digital design process in using CAD/CAM technology or so-called digital fabrication. It becomes an important issue recently as the CAD/CAM technology progressively act as the new digital design media in architectural design and construction process (Ryder et al., 2002; Kolarevic, 2003). Furthermore, in the field of architecture professional, some commercial computer systems had been developed on purpose of standardizes the digital design process in using CAD/CAM fabrication such as Gehry Technologies formed by Gehry Partners; SmartGeometry Group in Europe and Objectile proposed by Bernard Cache. Researchers in the research field like Mark Burry, Larry Sass, Branko Kolarevic, Schodek and others are enthusiastic about the exploration of the role of CAD/CAM fabrication as new design media in design process (Burry, 2002; Schodek et al., 2005; Lee, 2005).

summary This paper reviews empirical studies in product modeling and issues of CAAD, and then proposes a new way of thinking in object modeling for abstract design concepts – by using stairs as the subject of study because of its systematic nature and wide variety of forms. This object model works in the higher level over existing product models and deals with abstract concept only. It provides a mean for capturing design concepts and knowledge. Most stair generator in CAAD are only capable of making regular stairs, let alone those fascinating free-form stairs. The purpose of this research is to find a higher conceptual structure of stairs by the object modeling method, so virtually all types of stairs can be described and modeled. Therefore conceptual design in CAAD would be possible and useful for designers. A prototype on AutoCAD will be implemented to demonstrate how the conceptual structure works.

summary Parametric equation is one of the possible ways to generate free-form architecture in modern age. When working with mathematical software, designers need a way to bring surface mesh to CAD for further design. Surf_TM is an supplemental tool for AutoCAD to import and manipulate surface mesh data from Mathcad. Accompanying with a course taught in Harvard Design School, students gain knowledge in mathematics and use parametric equation as a design tool. This paper elaborates details of the course, the tool, how they work together, and example applications.

title Spark Wall: Control responsive environment by human behaviour
source International Journal of Architectural Computing vol. 14 - no. 3, 255-262
summary Responsive environment uses human–computer interface to improve how humans experience their surroundings. Many research aimed at different kinds of interactive environment modules with new digital tectonics or computation components. However, those new environments sometimes could be manipulated by components which are less user-friendly and complex than traditional counterparts. In this article, we implemented a real responsive interface – the Spark Wall system, which use 160 actuator modules as our responsive feedback interface and depth camera as sensing input. We built up multi-modal interface for different operating purposes allowing the user to control responsive environment with their behaviour. The user could change his or her body posture to change the pattern of the wall and moreover define touch-input area on any surface. From the user’s perspective, a responsive environment should be a simple system with understandable control modes. A responsive artefact should also be able to dynamically correspond to different methods of operation according to the user’s intentions.

title The complexity of formulating design(ing) grammars

summary We are concerned with the complexity of formulating rules within a design grammar, i.e., a grammar for designing. Our motivation comes from an active development of a design grammar using railway station design as a demonstration study. In this paper, we identify a number of difficulties that may arise when developing shape rules and present approaches for graphical rule specification that can serve to overcome these difficulties. Specifically, we present examples where drawing shape rules and augmenting these with control conditions or rule constraints offer insufficient support for the rules' intricacies, and propose conventions for drawing and specification that support the explication of these exemplar shape rules, aiming not to overly complicate the drawing and specification process. We borrow from other authors where appropriate, and do not concern ourselves with implementation issues, at this point.

summary This study is based on Chladni figures and tries to spatially extend its representation of sound. The current Chladni figures only see parts of the sound. There should be more spatial representation of sounds because they are transmitted in space. This study explores how to capture and reconstruct invisible sound information to create three-dimensional forms. A series of steps are taken to record Chladni figures of different frequencies and decibels. Pure Data is used to generate sounds. The Chladni figures are captured in Grasshopper and converted into point clouds. These point clouds are processed by using different algorithms to produce layers of superimposed state from which 3D forms of sound can be generated and fabricated. Through the proposed methods of processing and representation, sound not only stays at the level of hearing, but can also be seen, touched, and reinterpreted spatially. With the spatial forms of sound, viewers no longer perceive sound through single but multiple states. This can help us comprehend sound in a vast variety of ways.

summary In the era of three-dimensional (3D) informatics, the 3D point cloud modeling algorithm has the potential to further develop. In this study, we attempt to eliminate the limitations of the traditional reverse modeling method and directly turn point cloud data into the material for innovative architectural design by integrating 3D point cloud modeling into the CAD/CAM platform(Rhino/Grasshopper) most widely used by parametric designers. In this way, the randomly ordered point cloud model can be regenerated and reordered according to the designer's requirements. In addition, point cloud data can be spatially segmented and morphologically evolved according to the designer's preferences to construct a 3D model with higher efficiency and more dynamic real-time adjustment compared with the triangular mesh model. Moreover, when a computer vision technique is integrated into the point cloud design process, the point cloud model can be further used to more efficiently achieve rapid visualization, artisticization, and form adjustment. Therefore, point cloud modeling can not only be applied to the spatial structure presentation of building information modeling(BIM) but also can provide further opportunities for creative architectural design.
