title	Simulation of architectural lighting in a virtual environment - A case study on real and fake High Dynamic Range Images (HDRI)
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 566-572

summary	The early findings of this research were presented in eCAADe 2005 International Conference, Lisbon primarily to highlight the concept of High Dynamic Range Images (HDRI) when representing architectural spaces in the form of still images. An experiment had been carried out to compare the results between HDRI rendering and ‘conventional’ lighting simulation algorithms namely ray tracing and radiosity. The results were based on static and using the same exposure factors, when capturing HDRI. This project, funded by Intensification Research Priority Area (IRPA) grant continues to present and report HDRI results in a simulation environment. In this paper, we first briefly explain on the concept of real and fake HDRI. Then a comparison experiment is conducted to compare these two methods and discuss the impact and effectiveness of the illumination computation in architectural simulation environment. In order to carry out the experiment, a few models of the architectural scenes were developed. These models were then textured with real photos and manipulated with ‘shaders’, and further rendered using fake and real HDRI techniques. As for the fake HDRI, two methods were developed. The first was using an image as the ambient map and different exposures were created by increasing the value of Hue, V of HSV and saturation. The second involved a series of digital photos with the selection of the brightest and darkest area using Adobe Photoshop to establish the scale of luminosity. A few camera movements were triggered and position for ‘real-time’ rendering simulation. The result of the experiment has shown a significant improvement on the rendering time and quality of the rendering. Finally this paper suggests the selection criteria for choosing real and fake HDRI, and how each technique can be best utilized for architectural representations in a simulation environment.

title	Generating Architectural Spatial Configurations: two approaches using voronoi tessellations and particle systems
source	Proceedings of the Generative Arts conference, Milan, 2005
summary	It was one of the primary goals of the original Master’s programme in Computing and design at UEL in 1991 that we should work towards defining morphological generative processes for the conceptual design of architectural objects. These two papers offer a range of techniques which have been developed by two of this years MSc students (04-05) which show that we are getting close to this. The approaches range from computational geometric approaches (3d parametrics and voronoi diagrams) to emergent spatial organisation using agent based modelling. In many cases the resultant geometry is defined to the point where it can be transferred to advanced evaluation and fabrication systems, thus making this work sufficiently developed to begin to form a useful part in practical design processes.

title	Study on Factors of Distance Estimation at Architectural Presentation Tool in Immersive Virtual Environments
source	CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 2, pp. 116-122

summary	The VR technology has been used as the application of architectural presentation tool in the field of industry. The high immersion and intuitive visual information are the great merits of design evaluation when we are using the virtual environments. But the distortion of distance perception in VR is a problem when the accuracy of distance presentation is required to evaluate the preliminary design concept precisely. In this paper, we have carried out some experiments about distance estimation in the immersive virtual environments to verity the factors and their influence. First, we verify the difference of distance estimation in the real and the virtual hallway. The result showed that subjects underestimate the walked distance in the condition of virtual hallway. At the next experiment about the influence of image-resolution, we have figured out the resolution has affected on the distance estimation in the virtual environments.

title	The Digital Design Process in Contemporary Architectural Practice
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 751-759

summary	There is an increasing trend in contemporary architectural projects towards dependence upon digital processes for their organisation and technical evaluation of a range of design criteria. Digital representations are central not only to form generation and structural analysis, but also to the integration of fabrication and construction directly with the earlier design stages. It is important to bear in mind, however, that digital technology is only a means to an end which is the design process itself. Each technique of digital representation and analysis brings advantages and disadvantages to this process, and should therefore be described in these terms. It is becoming increasingly feasible to develop a rapid succession of distinct digital models, both geometric and dynamic, in early design stages. These can be tested and evaluated with respect to a range of analytical criteria, and the results of these analyses can affect further model development thus forming a cyclical process of 3-D digital model generation.

title	Using Cellular Automata to Generate High-Density Building Form
source	Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 249-258
summary	This paper presents an investigation into the use of cellular automata systems for the design of high-density architecture for Asian cities. In this architectural context, urban form is shaped by architectural solutions that are developed in a copy-and-paste manner. To this background, cellular automata are introduced and discussed with respect to the specific potential of cellular systems to support architectural design addressing large projects as well as cost and speed constraints. Previous applications of cellular automata to architectural design have been conceptual and are typically limited by the rigidity of classical automata systems as adopted from other fields. This paper examines the generative design potential of cellular automata by applying them to the re-modelling of an existing architectural project. From this application it is concluded that cellular automata systems for architectural design can benefit from challenging and adapting classic cellular automata features, such as uniform volumetric high-resolution models and globally consistent rule execution. A demonstration example is used to illustrate that dynamic, state-dependent geometries can support an architectural design process.

title	High Dynamic Range Image (HDRI) Rendering

summary	This paper suggests a method known as High Dynamic Range Image (HDRI) to pre-visualise architectural elements in three-dimensional (3D) environment used by Computer Graphic Imaging (CGI) film-makers to integrate 3D models and characters into live action background (special effect). This Intensification Research Priority Area (IRPA) grant project was developed to suggest ways to achieve effective rendering solution and composition of the final output. It will focus on experimental modelling of local cultural elements that provides solutions for radiosity-type effects and dirt shadings. A set of data from an established site (i.e. environment) was captured and represented in High Dynamic Range (HDR) file. This data is integrated with architectural elements (e.g. 3D objects) and then pre-rendered to get the 3D visualisation of the actual environment. Several different exposures were also captured and tested to establish the correct rendering and lighting condition. This earlier result shows that HDRI method provides accurate visualisation and drastically reduces the rendering time without compromising the data (images) with accurate lighting. This paper will demonstrate the process of HDRI, compare the visual impact with ‘radiosity’ technique and other related rendering solutions and present the results, which are useful for architectural animation, simulation and other modelling developments.

title	A 3D, interactive, multilayered, web-enabled model as a tool for multiple sets of end user groups: A case study and end user analysis
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 392-396
summary	This research undertakes a case study involving focus groups of potential end users, to identify how a successful digital tool could be created using new and emerging technologies, to accommodate the multiple needs of these end users. 2005 saw the completion of a research paper, which proposed that a single, 3 dimensional digital model of a city forming a core for many different information systems, is a better approach to the needs of the city than many individual models optimised for each information system. The case for the single 3D model was evaluated through the research, development, delivery and analysis of a prototype 3 Dimensional model of Wellington City, New Zealand, presenting different ‘views’ of information in Wellington: a rendered visualisation in an animated “walkthrough”; the impact of planning constraints on daylight; interactive “plots” of property values. The development and delivery of the prototype model was analysed in regards to how complex, costly and time consuming it may be to exploit one base model for several purposes; and also therefore how beneficial, affordable and potentially successful a single model may be. The prototype model was created to test the idea, and therefore provided conclusions based on a limited feasibility analysis - with four potential information layers modelled and two potential delivery methods tested. The prototype model and user analysis results were presented in a research report that suggested further research and development of a single model could be very beneficial: Positive feedback from potential end users and data providers, and examples of potential data mining opportunities forming the basis of the need for continued research. 2006 sees the research continue as an 18 month research project in conjunction with an industry partner, Terralink International, (http://www.terralink.co.nz/). Terralink International Limited provides GIS and mapping solutions which according to their web site: “enable better business management.” The company maintains a national resource of “imagery, cartography, and spatial databases” and provides consultancy services linking these to company databases through GIS systems. The research investigates the potential for 3 dimensional, interactive, multilayered models to enhance delivery of information to multiple end user groups. The research method uses functional prototypes in end-user focus group workshops. These workshops, consisting of a combination of presentations, hands on interactive examples, group discussions, and individual feedback surveys, aim to establish how a tool might best be developed to communicate to a wide range of end users. The means of delivery whether a stand alone tool or web-based is a key element of the user group workshop assessment process. Note: The submission of the prototype tool (via video or interactive media) would greatly increase the effectiveness of the research presentation. Ability to include such media would be greatly appreciated.

title	Real-time Simulations Using Learning Algorithms for Immersive Data Visualization in Buildings
source	International Journal of Architectural Computing vol. 3 - no. 3, 265-280
summary	Computational Fluid Dynamic (CFD) simulations are used to predict indoor thermal environments and assess their response to specific internal/external conditions. Although computing power has increased exponentially in the past decade, CFD simulations are still time-consuming and their prediction results cannot be used for real-time immersive visualization in buildings. A method that can bypass the timeconsuming simulations and generate "acceptable" results will allow such visualization to be constructed.This paper discusses a project that utilizes a supervised Artificial Neural Network (ANN) as a learning algorithm to predict post-processed CFD data to ensure rapid data visualization. To develop a generic learning model for a wide range of spatial configurations, this paper presents a pilot project that utilizes an unsupervised Reinforcement Learning (RL) algorithm. The ANN technique was integrated with an interactive, immersive Augmented Reality (AR) system to interact with and visualize CFD results in buildings. ANN was also evaluated against a linear regression model. Both models were tested and validated with datasets to determine their degree of accuracy. Initial tests, conducted to evaluate the user's experience of the system, indicated satisfactory results.

title	MIND-ING THE TASK
source	SID 2005, Proceedings of the 4th Social Intelligence Design Workshop, Stanford University, March 2005 (CD Rom)
summary	In this paper we describe our findings regarding the role of context in usability evaluation, particularly how the nature of the tasks can affect the users’ perception of the performance of a particular application. Our findings show a relationship between the variation in the nature of the tasks used for usability evaluation and the way in which subjects evaluate these applications afterwards using user -administered questionnaires. Our findings contradict the absolute benchmarking goal of some of these tools, and pose questions about the possibility of achieving that kind of benchmarks in software usability evaluation.

title	THIS IS NOT A CAUCUS RACE. OR WHY UPGRADES IN GUIS WILL (NOT NECESSARILY) MAKE USERS (INSTANTLY) MORE PRODUCTIVE
source	SID 2005, Proceedings of the 4th Social Intelligence Design Workshop, Stanford University, March 2005 (CD Rom)
summary	In this paper we discuss the impact that upgrading applications may have across different users, using for this purpose the case of GUI improvements to a market leading drafting application. Our findings show that even though there are improvements in productivity that can be associated with the changes to the GUI, these improvements will not necessarily affect evenly all users, suggesting an interaction between the level of expertise and variations in productivity.

title	A Quantitative Method to Compare the Impact of Design Mediums on the Architectural Ideation Process.
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 539-556.
summary	If we compare the architectural design process to a black box system, we can assume that we now know quite well both inputs and outputs of the system. Indeed, everything about the early project either feasibility studies, programming, context integration, site analysis (urban, rural or natural), as well as the integration of participants in a collaborative process can all be considered to initiate and sustain the architectural design and ideation process. Similarly, outputs from that process are also, and to some extent, well known and identifiable. We are referring here, among others, to the project representations or even to the concrete building construction and its post-evaluation. But what about the black box itself that produces the ideation. This is the question that attempts to answer the research. Currently, very few research works linger to identify how the human brain accomplishes those tasks; how to identify the cognitive functions that are playing this role; to what extent they operate and complement each other, and among other things, whether there possibly a chain of causality between these functions. Therefore, this study proposes to define a model that reflects the activity of the black box based on the cognitive activity of the human brain. From an extensive literature review, two cognitive functions have been identified and are investigated to account for some of the complex cognitive activity that occurs during a design process, namely the mental workload and mental imagery. These two variables are measured quantitatively in the context of real design task. Essentially, the mental load is measured using a Bakan's test and the mental imagery with eyes tracking. The statistical software G-Power was used to identify the necessary subject number to obtain for significant variance and correlation result analysis. Thus, in the context of an exploratory research, to ensure effective sample of 0.25 and a statistical power of 0.80, 32 participants are needed. All these participants are students from 3rd, 4th or 5th grade in architecture. They are also very familiar with the architectural design process and the design mediums used, i.e., analog model, freehand drawing and CAD software, SketchUp. In three experimental sessions, participants were asked to design three different projects, namely, a bus shelter, a recycling station and a public toilet. These projects were selected and defined for their complexity similarity, taking into account the available time of 22 minutes, using all three mediums of design, and this in a randomly manner to avoid the order effect. To analyze the two cognitive functions (mental load and mental imagery), two instruments are used. Mental imagery is measured using eye movement tracking with monitoring and quantitative analysis of scan paths and the resulting number and duration of participant eye fixations (Johansson et al, 2005). The mental workload is measured using the performance of a modality hearing secondary task inspired by Bakan'sworks (Bakan et al.; 1963). Each of these three experimental sessions, lasting 90 minutes, was composed of two phases: 1. After calibrating the glasses for eye movement, the subject had to exercise freely for 3 minutes while wearing the glasses and headphones (Bakan task) to get use to the wearing hardware. Then, after reading the guidelines and criteria for the design project (¬± 5 minutes), he had 22 minutes to execute the design task on a drawing table allowing an upright posture. Once the task is completed, the subject had to take the NASA TLX Test, on the assessment of mental load (¬± 5 minutes) and a written post-experimental questionnaire on his impressions of the experiment (¬± 10 minutes). 2. After a break of 5-10 minutes, the participant answered a psychometric test, which is different for each session. These tests (¬± 20 minutes) are administered in the same order to each participant. Thus, in the first experimental session, the subject had to take the psychometric test from Ekstrom et al. (1978), on spatial performance (Factor-Referenced Cognitive Tests Kit). During the second session, the cognitive style is evaluated using Oltman's test (1971). Finally, in the third and final session, participant creativity is evaluated using Delis-Kaplan test (D-KEFS), Delis et al. (2001). Thus, this study will present the first results of quantitative measures to establish and validate the proposed model. Furthermore, the paper will also discuss the relevance of the proposed approach, considering that currently teaching of ideation in ours schools of architecture in North America is essentially done in a holistic manner through the architectural project.

title	A Case-Based Decision Support System for Housing Refurbishment
source	CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 2, pp. 288-299
doi	https://doi.org/10.52842/conf.caadria.2005.288x.r0c
summary	Effective communication is a key for ensuring quality of housing refurbishment. This paper provides a framework of decision support system for housing refurbishment that helps designers better communicate with tenants who generally lack expert knowledge and can not express their needs clearly. The framework is constructed using Case-Based Reasoning (CBR) for retrieving past similar cases to meet the challenges and demands of the present refurbishment project at hand. With the help of the system, users can retrieve past cases that match the users’ requirements and revise them to meet current needs. It can also be used as design criteria for evaluating the final product to ensure its conformance with the initial planning. A test case is used to demonstrate the system’s suitability. The effectiveness of this system is supported by a post-experiment evaluation and interview with the tenant concerning his satisfaction on the refurbishment.

title	Can a Computer Implementation Based on Set Grammars Allow Emergent Shapes?
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 507-514
doi	https://doi.org/10.52842/conf.ecaade.2005.507
summary	In a previous paper, (Romão 2005) it was shown that a designer could create his own rules and combine them for application in a deterministic way using a computational device based on Set Grammars called SGtools. Using this device, the designer can assess the results in a visual manner and then change the rules without any knowledge of a programming language. This work examines whether SGtools can deal with emergence by coupling the representational abilities of Set Grammars with the search power of hybrid algorithm inspired on Genetic and Taboo search algorithms. The use of this search algorithm enhances the ability of the designer to explore solutions in practical time thereby enabling him/her to find unexpected, emergent solutions.

summary	This paper demonstrates a novel method to generate house designs completely from 3/4” plywood sheets. A shape grammar routine is employed to divide an initial solid shape into constructible components for fabrication by CNC wood routing. The paper demonstrates programmable functions that can be performed using CAD scripting. Future goals for the grammar are to develop CAD programs for digital fabrication using CNC routers. The programs will automate the fabrication process allowing the designer to focus on the visual aspect of design evaluation at any scale with little concern for constructability.

summary	In 2005, the rural housing deficit in Colombia was 1,600,000 units, which is equivalent to 68.25% of the total households. This very high number shows the difficulties faced by public policies on rural housing. This deficit is partly due to logistical problems related to the supply of materials and complexity in construction processes. It is necessary to explore new alternatives to offer more and better homes at lower costs. The research project presented in this manuscript started in 2013 as an initiative to reduce the housing deficit. It proposed to build a rural housing prototype integrating digital manufacturing processes. The performance of part of the structural and enclosing system was evaluated during a first iteration process to include changes in a second iteration later. With the adjustments to the design process discussed here, the prototype is expected to be built and tested to measure its efficiency and functioning.

source	Proceedings of the 9th Iberoamerican Congress of Digital Graphics Graphics / ISBN 978-1-59975-306-5] Lima (Perú) 21-23 november 2005, 826 p.
summary	Paradoxically, one of the most difficult but enjoyable things we do is to imagine. To open the eyes of our mind and see what no one else can see. We see images of things that are yet to be and through the same skill we devise ways in which to make them happen. We design the future in the form of environments, graphics, products, films, and a growing range of new media. Our ability to develop a vision and to visualize it is a gift that we are called to cultivate and put to good use. We have been privileged with a great responsibility. In the process of developing a vision and communicating that vision to others, we “visualize”. Visualization can be a very private experience in which we are alone with mental images that help us shape our vision. In other instances visualization can be a component of mass communication. Visualization can be a means or can be an end. It can be a small architectural sketch on a paper napkin or a mega-graphic covering a high-rise building, an airplane or a ship. In every case, the relationship between vision and visualization is a mutually supportive articulation of what our eyes and our minds can see. Our vision of the role of computers in the art and science of visualization is in constant development. Computer visualization can support an intimate dialog between a designer and his/her vision. It can translate and communicate that vision to a larger audience and in the hands of a new-media artist it can actually constitute his/her vision. The 9th Annual Conference of SIGraDI (Ibero American Society for Computer Graphics) will explore our collective vision on the future of digital visualization and digital media in Environmental Design, Product Design, Graphic Design, Cinematography, New Media, and Art. Authors are invited to share their research work with a focus on how it contributes to shape a collective understanding of the past, awareness of the present, and vision of the future in our multiple disciplines.

title	Architecture as the Computer Interface: 4D Gestural Interaction with Socio-Spatial Sonification
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 763-770

summary	Architecture today extends far beyond designing building shells and material, peripheral boundaries. Arguably, it has always been, and shifts increasingly in contemporary environments towards, designing space and interaction with space. Hence, the role of the designer includes integration of computing in architecture through ambient display and non-tactile interaction. This paper explores a framework in which the architecture is the computer interface to information sonification. (Sonification is automatically generated representation of information using sound). The examples in this paper are Emergent Energies, demonstrating a socio-spatially responsive generative design in a sensate environment enabled by pressure mats; Sensor-Cow using wireless gesture controllers to sonify motion; and Sonic Kung Fu which is an interactive sound sculpture facilitated by video colour-tracking. The method in this paper connects current information sonification methodologies with gesture controller capabilities to complete a cycle in which gestural, non-tactile control permutes and interacts with automatically-generated information sonification. Gestural pervasive computing negotiates space and computer interaction without conventional interfaces (keyboard/mouse) thus freeing the user to monitor or display information with full mobility, without fixed or expensive devices. Integral computing, a blurring of human-machine boundaries and embedding communication infrastructure, ambient display and interaction in the fabric of architecture are the objectives of this re-thinking.

source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 634-639
summary	This paper describes the progress of a multi-disciplinary team from Texas A&M University to digitally document the command post at one of the most significant historic sites of the D-Day landings: Pointe du Hoc. The methods used to collect survey data for both the production of 2D Historic American Building Survey drawings and for the 3D digital model are described. The processes used to produce the 3D digital model involves collecting survey data using digital photogrammetry and then applying surfaces to that model using modeling software. The results of the first season’s survey work are described and illustrated. Finally, the problems encountered with lighting and the digital photogrammetry processing are discussed and recommendations made for future work.

summary	Design knowledge abstracted from cases is important for designers. This paper is aimed to build an agent to detect those correlations between explicit features of design cases and relevant design problems. Using the data mining algorithm, we have accumulated a list of keywords about design problems and their relevant concept from textual information of a case library, and established their semantic ontology by clustering their semantic and sentence structural relations from previous studies. Meanwhile, we also established another hierarchical ontology of explicit design case features by applying design domain knowledge. Then, through mapping semantic relations of relevant keywords between two ontologies, the system will become more sensitive to the correlations of design case features and relevant design problems. Finally, a graphical interface is built to visualize these correlations and help user to recognize useful design knowledge cached in design cases.

title	A Computational Approach to the Reconstruction of Surface Geometry from Early Temple Superstructures
source	International Journal of Architectural Computing vol. 3 - no. 4, 471-486
summary	Recovering the control or implicit geometry underlying temple architecture requires bringing together fragments of evidence from field measurements, relating these to mathematical and geometric descriptions in canonical texts and proposing "best-fit" constructive models. While scholars in the field have traditionally used manual methods, the innovative application of niche computational techniques can help extend the study of artefact geometry. This paper demonstrates the application of a hybrid computational approach to the problem of recovering the surface geometry of early temple superstructures. The approach combines field measurements of temples, close-range architectural photogrammetry, rule-based generation and parametric modelling. The computing of surface geometry comprises a rule-based global model governing the overall form of the superstructure, several local models for individual motifs using photogrammetry and an intermediate geometry model that combines the two. To explain the technique and the different models, the paper examines an illustrative example of surface geometry reconstruction based on studies undertaken on a tenth century stone superstructure from western India. The example demonstrates that a combination of computational methods yields sophisticated models of the constructive geometry underlying temple form and that these digital artefacts can form the basis for in depth comparative analysis of temples, arising out of similar techniques, spread over geography, culture and time.
