title	Grammar Representations to Facilitate Style Innovation - An Example From Mobile Phone Design
doi	https://doi.org/10.52842/conf.ecaade.2006.320

summary	Previous research in generative design has suggested that shape grammar transformations could be used for developing new design styles by the systematic modification of grammars that encode existing styles. Our research explores how such grammar transformations can be facilitated to be responsive to changes in design style requirements. For this it is important to consider the structure and organization of rules, as well as the description of the styles of designs generated by a grammar. Using an example of mobile phone design, we outline the development of a flexible grammar structure that is conducive to transformations. The grammar is augmented with a style description scheme based on the concept of semantic differential to map the style characteristics of grammar components. These measures could be significant for driving purposeful grammar transformations for style adaptation and innovation.

title	An Analysis of the Applications of Rapid Prototyping in Architecture
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	Rapid prototyping (RP) techniques are widely used within the design/manufacturing industry and are well established in manufacturing industry. These digital techniques offer quick and accurate prototypes with relatively low cost when we require exact likeness to a particular scale and detail. 3D modeling of buildings on CAD-systems in the AEC sector is now becoming more popular and becoming widely used practice as the higher efficiency of working with computers is being recognized. However the building of scaled physical representations is still performed manually, which generally requires a high amount of time. Complex post-modernist building forms are more faithfully and easily represented in a solid visualization form, than they could be using traditional model making methods. Using RP within the engineering community has given the users the possibility to communicate and visualize designs with greater ease with the clients and capture any error within the CAD design at an early stage of the project or product lifecycle. In this paper, the application of RP in architecture is reviewed and the possibilities of modeling architectural models are explored. A methodology of developing rapid prototypes with 3D CAD models using methods of solid freeform manufacturing in particular Fused Deposition Modeling (FDM) is presented and compared against traditional model making methods. An economical analysis is presented and discussed using a case study and the potential of applying RP techniques to architectural models is discussed.

title	ILUDS - An Interactive Land Use Database System for Intelligent Cities
doi	https://doi.org/10.52842/conf.ecaade.2006.276
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 276-279
summary	This paper presents the i-putra business channel, a portal that has been completed with a comprehensive database of information relating to commercial and residential properties, and other on-going development components of Putrajaya, one of Malaysia’s intelligent cities. Designers were provided with multimedia-rich information of spaces before making a selection through the Interactive Land Use Database System (ILUDS) which hosted more than 67,000 units of residential and commercial areas in Putrajaya. The database was developed based on category searching features that aimed to be the one-stop brief explanatory system on the Internet. ILUDS depicts an innovative idea for city and urban development to prepare information and virtual interactivities for a better usage in a ‘soft city’ design. The system has the underlying structure that allows for partitioning and ease of handling within which the data can be structured under a graphical interface that facilitates editing, manipulation, attribution and updating. This attribute of city information and associate data offers users a different level of interactivity and provides effective use on architectural and city information.

title	Simulation of architectural lighting in a virtual environment - A case study on real and fake High Dynamic Range Images (HDRI)
doi	https://doi.org/10.52842/conf.ecaade.2006.566
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	EMO-Space: A Computational Model for Interaction between Emotions and Space
doi	https://doi.org/10.52842/conf.caadria.2024.3.401

summary	Architectural space can trigger emotion (Zumthor, 2006). Psychologists Mehrabian and Russell (1974) proposed PAD model, presenting eight emotions as a means for psychologists to self-assess the emotional conditions of human experience and to provide people with a way to conceptualize the impact of cognitive structure. The Brain-Computer Interface (BCI) combines with computer operations to decode and calculate different brain waves generated by human emotions, supporting the convenience and wisdom of human life. The integration of the PDA model and BCI technology will offer an understanding of the interactive relationships between space and emotion. The purpose of this research is to construct a computational model called EMO-Space, which can autonomously support space interaction through the understanding of human emotions. Based on the PAD model, the integration of BCI, the mechanism of emotional transformation, and the control of message transmission are explored. Subsequently, the computational model is proposed and simulated. EMO-Space will provide the basis for the intelligence of emotional space in the future, such as in elderly care and spatial healing.
