title	Image Morphing for Architectural Visual Studies
doi	https://doi.org/10.52842/conf.caadria.1997.397
source	CAADRIA ‘97 [Proceedings of the Second Conference on Computer Aided Architectural Design Research in Asia / ISBN 957-575-057-8] Taiwan 17-19 April 1997, pp. 397-406
summary	The purpose of this paper is to suggest and demonstrate how image interpolation, as a tool, can facilitate architectural illustration of design content and process. This study emphasizes a design-oriented image transition process that is distinguished by two types of morphing: process and source. A morp model is presented with components of input, function, output and constraints. Based on a model’s definition, a matrix is used to illustrate the relationship between the two source images by referring to origin, reference plan, configuration, time, etc. Morphing contents emphasizes changes of pixel, outline (2D or 3D), and order. Possible applications in architectural visual studies include morphology study, comparison building renovation before and after, dynamic adjustment, quantitative measurement, dynamic image simulation, and model and image combination.

title	Visualization Management and Inspection for Plumbing Construction Quality Control
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	This research compares the working process at a construction site with the shop drawings made by a plumbing inspector for installed pipes. This study compared the 2D plumbing shop drawings with the 3D point cloud of the toilet in a campus building. A long-range 3D scanner was used to retrieve the point cloud records of pipes to build a visualization management system. The visual comparison was used to locate pipes at the construction site. We found the differences could be identified easily between the point cloud and shop drawings. The presence of point clouds created a new method to inspect plumbing locations, as a way to verify construction quality.

title	A Study of the Location of Fire Egress Signs by VR Simulation
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 311-316
summary	The purpose of this paper is to present a suggestion for the location of fire egress signs along a corridor in a building. The suggestion is made based on a virtual reality simulation of human behavior while rooms are on fire, particularly in a public Karaoka TV entertainment center (KTV). Both the rooms and smoke were modeled to simulate similar situations in which people were asked to find their routes to an egress. Case studies were made of the occurrence of two local severe fire disasters, the official investigation of damages, and related building codes. The simulation concluded that the traditional designation of egress signs at a higher location or just above the door frame may be not function appropriately in indicating the location of exit in case of fire. Since smoke is usually lighter than air and is accumulated closer to the ceiling level, either human vision or egress signs are very likely to be blocked by the darkness of smoke. Vision is additionally restricted because people are suggested to lower their body position to avoid smoke while escaping. Suggestion of alternate location of signage is also made in the research.

summary	This paper describes a layout generation system that is realized by adapting the design problem formation and design process of the well-known SAR method. The purpose is to examine the idea that some certain types of design problems can be greatly simplified by conventional design techniques such as hierarchical decomposition, zoning, module, and most importantly, the concept of “support”, which is a spatial framework that dissects the planning site into sectors and zones of various spatial characteristics.

title	A Web-Based Agent Framework for Collaborative Design-Build Communication
doi	https://doi.org/10.52842/conf.caadria.2003.055
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. 55-68
summary	The Internet connects the globe as a whole and at the same time pushes the competition increasing dramatically. Multidiscipline and distributed collaborative design-build in architecture, engineering and construction (A/E/C) companies can gain foster competitive advantage, improved designs, and more effective management of construction facilities. However collaboration can often fail, since it involves different professions who often hold different goals and also one-off organizations also build obstacles to collaboration. This paper presents a web-based agent framework to support communication, to facilitate shared understanding amongst the participants and to inspire teamwork. This paper proposes a multi-agent social interaction framework as the communication model of design-build projects. The conceptual framework emp hasizes process-centric learning and the creation of group agreements within design-build collaborative activities, which help facilitate conflict migration. In addition, based upon web agent technology, this communication framework providing an intelligence distribution opportunity for the for the A/C/E industry to introduce a new and innovative paradigm of collaborative design.

title	The Development of a Glasses Design Support System
doi	https://doi.org/10.52842/conf.caadria.1996.091
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. 91-97
summary	While looking at glasses, we will have various sensation on their forms, colours, textures etc. These feelings direct us to decide which pair of glasses to buy. This study tries to find out the relationship between human sensation and glasses design; that is, to figure out what kinds of forms will excite what kind of human sensation. By adopting this relationship, we also propose a computer support system which can automatically generate appropriate glasses forms in response to the expectation of consumers. In this study, we first collect several adjectives which can express the human sensation on glasses designs. Then, in an experiment, subjects are asked to evaluate a set of glasses in order to acquire the ratings of those adjectives. We further analyze the formal elements included in different glasses, multivariate analysis and the neural networks are used to decide which design of each element are more likely to excite a specific human sensation. These results then are built as a knowledge base of a support system which includes an inference engine to assist a designer to produce new glasses design. By receiving the input of desired adjectives, this system will find out the most preferred elements for each adjective and integrate them into some appropriate design prototypes for further modification.

title	3D Scans of As-Built Urban Scenes in A City Scale
doi	https://doi.org/10.52842/conf.caadria.2009.297
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 297-306
summary	The purpose of this research is to build digital urban landscape, based on as-built environmental information. Scans were made to an expressway and surrounding buildings through the center of a city. A 3D long-range laser scanner was used to record buildings, plants, and open spaces in a static configuration, plus the records of pedestrians, vehicles, objects in a dynamic form. As the scan tolerance can be controlled in less than 4 mm/50 m, the final urban information management system creates a precise description of objects with colors and textures feasible for internet browsing as well as for infrastructure dimensioning and construction monitoring.

summary	The implementation of digital design workflows is an opportunity to facilitate the knowledge exchange between the industry and research, required in the face of the climate emergency. This paper presents outcomes of a series of digital design to fabrication workshops, resulting in three-party collaboration between an international architectural design firm, a university, and a global food producer. The paper presents an initial step towards an integrated material system based on an abundantly available industrial by-product of sugar manufacturing. The idea of topological interlocking has been used as a concept to define components-based system for the novel material, tested in a scaled prototype with university students.

title	Deep-learning Point Cloud Classification for Estimating the Weight of Single-material Construction and Demolition Waste of Unknown Shape
doi	https://doi.org/10.52842/conf.ecaade.2023.2.609
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 2, Graz, 20-22 September 2023, pp. 609–618
summary	Construction and demolition waste (CDW) generated during the demolition of buildings must be classified on site because it contains recyclable waste. Automating the classification work has been identified as a countermeasure to labor costs and safety issues, and research is being conducted to develop automatic devices. However, they lack the ability to estimate the weight of the waste. If weight estimation was possible, then the waste could be transported up to the load-bearing weight, thereby reducing the time required for both the demolition and removal of buildings during redevelopment and the disposal of waste generated by disasters. Automatic classification and weight estimation of CDW is difficult due to the unknown shapes of the waste. This study uses point clouds and 3D instance segmentation to enable both automatic classification and weight estimation that can be applied to CDW of unknown shapes and made of a single material without holes or cavities. Of the 27 pieces of CDW used for validation, the shapes and classes of 19 pieces could be classified automatically, and the percentage error between the estimated and actually measured weight was 12.9%±6.5%.

summary	The purpose of this research is to develop the CAFM system that supports the cost management related to the building maintenance. Furthermore, we examine the possible implementation of CAFM as the supporting tools of medium-long term planning and fiscal year planning of the Facility Management. The function of the building-maintenance-system-oriented-Life-Cycle Cost (LCC)-supporting CAFM system is the feasibility of reference with the relating information database, which are later used for comparative analysis. The following is a detailed explanation of its functions:1) Outlined data display function of the building parts and materials. 2) 3-dimensional CAD models management. 3) LCC display function of building parts and materials. 4) Search function. This system supports the development of an efficient maintenance planning, and an efficient undertaking of the maintenance program. The concrete effects are as follow, (1) Cost-efficient building maintenance planning. (2) Building value increased by appropriate budget planning of maintenance. (3) Processing load and time are shortened. (4) Human mistakes are decreased.

summary	Despite the effort of Korean government to vitalize BIM adoption in AEC industry, the domestic adoption of BIM is still in its initial step. Particular in design field where medium and small firms being the majority, shows lower level of BIM adoption. The primary reason for this can be considered as lacking of necessities caused by uncertain benefits of BIM. Therefore, it is time to develop the objectives, quantifiable and qualitative measurement system of BIM performances. The purpose of this study is to suggest the BIM Performance Measurement System for architectural design firms. In achieving this, the authors have developed Balanced Scorecard (BSC) and validated its appropriateness by questionnaire survey with experts and performing statistical analysis. This development can be contributed to the voluntary BIM adoption by visualizing the detailed benefit of BIM and to the improvement of enterprise competitiveness by facilitating management of design process and estimating future outcome.

summary	With the growing responsibility for the environmental load of building, the demand for sustainable building is increasing. Sus- tainable design requires an enormous amount of information, and most of this information can be captured by Building Information Modelling (BIM). In this context, the management of information in a BIM object as a container for exchanging information is necessary for analyzing a building’s sustainability. However, there are problems in generating a reliable sustainability simulation model from BIM, such as the inefficiency of required information and low accessibility to a proper BIM object. In order to provide a new approach for generating a reliable sustainability simulation model in a BIM-based design pro- cess, this study suggests the integrated management environment of the property information of a BIM object.

title	Data enhancement for sharing of ship design models
source	Computer-Aided Design, Vol. 30 (12) (1998) pp. 931-941
summary	Within a shipyard, many designers each having their own design objective cooperate in a complex design situation where a variety of software tools run on differenthardware platforms. The exchange of design data models among these heterogeneous CAD systems is a difficult task because the systems involved have different datastructures optimized for their own functions. CAD geometric models are represented by different schemes such as 2D graphic entities, 3D wireframe, 3D surface model,and solid B-Rep/CSG model. A data exchange usually requires topological modifications of CAD data. This paper presents a strategy of CAD data enhancement for thepurpose of data exchange that includes topological changes of geometric models. As a practical example, a shipbuilding product model with shipbuilding features isimplemented according to the STEP methodology. Its geometric data is enhanced through a non-manifold modeler to a data set valuable to downstream applications suchas a FEM solver or a detail design system. The ACIS modeler that supports a non-manifold data structure is used for low-level geometric operations.

summary	As well as learning traditional design techniques, students in architecture courses learn how to use powerful workstations with CAD systems, color scanners and laser printers and software for the rendering, compositing and animating of their designs. They learn to use raytracing and radiosity rendering systems to provide visual realism, alpha-channel compositing systems to put a client in the picture (literally) or the design in situ, and keyframe animation systems to allow realistic walkthroughs. Student Presentations are now based on videos, photographic slides, slide shows or real time animation. Images (as data files) are imported into full color publishing systems for final year thesis presentation. The architectural graphics environment at Curtin University facilitates the integration of slide and video examples of raytraced and chroma-keyed images with computer aided design techniques for architectural student presentations.

title	Fast Phong Shading
source	Computer Graphics (20) 4 pp. 103-106
summary	Computer image generation systems often represent curved surfaces as a mesh of polygons that are shaded to restore a smooth appearance. Phong shading is a well known algorithm for producing a realistic shading but it has not been used by real-time systems because of the 3 additions, 1 division and 1 square root required per pixel for its evaluation. We describe a new formulation for Phong shading that reduces the amount of computation per pixel to only 2 additions for simple Lambertian reflection and 5 additions and 1 memory reference for Phong's complete reflection model. We also show how to extend our method to compute the specular component with the eye at a finite distance from the scene rather than at infinity as is usually assumed. The method can be implemented in hardware for real-time applications or in software to speed image generation for almost any system.

summary	Fused Material Deposition (FDM) is a widely used technology for desktop 3d printing which has the potential to close consumer cycles by printing recycled materials. However, its use in architectural scale applications has still to be further explored. This paper presents the design, construction and implementation of a 3d printing system of recycled plastic pellets. We describe the device, its systems and parameters, as well as the custom tool path calculations and material experiments. We argue for this technology as a viable way of implementing FDM on larger scales and identify key challenges that present themselves as we explore the fabrication of meso scale formal artifacts.
