summary To make whole one image on screens that is generated by many computers and synchronization among computers, there is a need for a network software environment for multi-projector display system. Although the development costs increase for parallel programming for multi-projector display system, there is a possibility that the program cannot be executed at an enough speed since the network bandwidth might become a bottleneck. There are some software environments for that kind of multi-projector display system like Chromium that is latest version of WireGL (Humphreys, 2001&2002). WireGL is a kind of Client-Server Model, which one rendering server sends the data of rendering to many computers. While it can use the application without modification of source, it requires heavy network traffics. The other type of operating software is VR Juggler (Cruz-Neira, 2002), and CAVE Library that is a kind of Master-Slave Model. In the Master-Slave Model, every computer has same application programs to render the image that only keep the synchronization of rendering and events. But, these programs require a specialized skill and knowledge to modify the source of program for the certain rendering PC-Cluster system.

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.

summary Cyberspace is more malleable than a physical environment, so it can afford much wider range of responsiveness. By applying the concept of place-making, we are experimenting virtual environments which are responsive to their users’ context-specific needs. Since objects are essential components that anchor the users’ various activities, having interactive objects in a 3D virtual environment is a major design concern for developing a dynamic and experience-rich virtual environment. We propose a layered agent model for intelligent behavior control of 3D objects, based on constraint solving process.

summary The space layout planning problem belongs to the class of NP-hard problems with a wide range of practical applications. Many algorithms have been developed in the past, however recently evolutionary techniques have emerged as an alternative approach to their solution. In this paper, a genetic programming approach, one variation of evolutionary computation, is discussed. A representation of the space layout planning problem suitable for genetic programming is presented along with some implementation details and results.

title Parametric Design and Analysis of Dynamic Louver for Optimized Daylighting in High-Rise Office Buildings

doi https://doi.org/10.52842/conf.caadria.2023.1.493
summary This paper presents an innovative approach to optimize daylighting in high-rise office buildings, through parametric analysis of dynamic shading system designs. This study concentrates on a kinetic shading angle optimization plot to determine the optimum angles of the dynamic horizontal louver shading systems at specific times with integrated operationalization equations and parametric performance simulations. Solar irradiance and daylighting were considered as performance metrics in this research, which investigated the integration process using the operationalization method in order to find an optimal rotational angle of dynamic horizontal louver shading systems at the specified time. In this study, dynamic horizontal louver shading systems were positioned in different orientations (Southeast and Southwest) to evaluate the effect of the shading’s tilt angles on daylighting. To quantify the daylight quality, maximum and average illuminance were obtained from the raw illuminance on the work plane. At the end, the outcomes of the analyses as well as the optimized angle of the dynamic louver shading were compared to a base case with no shading, and the results prove that dynamic louver with the support of an operationalization method to find optimum angle and testing with parametric performance software leads to optimizing the daylighting performance, enhancing it by approximately 14%.

title Creating Immersive Virtual Landscapes A User-Centered Approach to Enhance Depth Perception in Head-Mounted Displays
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 1, Graz, 20-22 September 2023, pp. 149–158
doi https://doi.org/10.52842/conf.ecaade.2023.1.149
summary This paper investigates the effects of color, luminance, and transparency as depth distortion cues in Virtual Reality (VR) Head-mounted Displays (HMD). The aim is to tackle more in-depth immersion: focusing on interaction accuracy with transparent objects in HMDs. Due to the illumination and absence of texture, transparent objects are mainly displayed with colors. Recently, studies on transparent hands and objects have elucidated potential approaches regarding interaction with transparent elements. However, findings have not considered color and luminance as depth distortion cues for interacting in virtual landscapes. This paper used the forced-choice pairwise comparison experiment method and evaluated data based on the Kendall coefficient of agreement and consistency. Reverse effects of transparency on color and luminance are discovered. Cool colors are perceived nearer than warm colors in 90% transparency. Dark colors are sensed closer than bright colors in high transparency levels. These results reject the classical effects of color and luminance within VR HMDs. These findings help VR design tool developers who emphasize a particular use of depth cues. Designers can utilize the studied effects of color and luminance on transparent objects as an advantage in designing more interactive and immersive virtual landscapes.

summary Over the past two decades, advances in computation, digital fabrication, and robotics have opened up new avenues for the design and production of complex forms, emergent processes, as well as new levels of efficiency. Many of these methods, however, tend to focus on a specific tool, such as the industrial robotic arm. Due to their initial costs and space/power/safety requirements, difficulties associated in creating automated workflows and custom tooling, as well as the need for reliable/repeatable procedures, these tools are often out of reach for the average designer or design institution. Additionally, these tools are typically treated as methods of production rather than collaborators, leaving outcomes that can feel void of craft, with the appearance of a typical CNC-machined object. Rather than focusing on a specific production tool for manufacturing, this paper investigates a novel method for holographic handcraft-based production. This holographic augmentation—of simple and easily attainable analog tool sets—allows for the creation of extremely complex forms with high levels of precision in extremely short time frames. Through the lens of the recently completed steam-bent timber installation [BENT] produced at the Tyler School of Art, this paper discusses how Microsoft HoloLens in conjunction with the Fologram software plug-in can be integrated into the entirety of design and production processes as a means of producing a new typology of digital craft.

source CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 917-926
summary Many of the emblematic buildings constructed at present shows many formal and technological innovations that have not been satisfactorily resolved by the existing CAAD software. Frank 0. Gehry's Guggenheim Museum in Bilbao is a good example of architecture whose shapes and design are very advanced from the concepts and tools used by CAAD. The search for new creative resources, from the educational and professional point of view, must be a priority. This will be the only way to get that CAAD contributes essentially in the process of architectural innovation, instead of merely being a reproduction tool. From this viewpoint the computer exploration of the three dimensional form is presented in here. The concept of abstract art, that has been successfully applied to painting and sculpture in this century is used as a way to experiment, design and create architecture. This paper juxtaposes three approaches, three different ways of understanding the abstract character, with the purpose to create new objects and environments, which are exclusively characteristic for computer space. This juxtaposition shows how creative and innovative activities in the field of CAAD can be developed using different intellectual bases: intuition, mathematical formulas and genetic algorithms.

title Architecture not Aided – Architecture Transformed
source CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 193-207
summary Permeating of new technologies (computer aided design) into architectural design causes essential changes in its structure. It is the process, set of mutually interrelated different social, political, cultural occurrences, which happen in the present time. Everything what is new, brings either fear or unreliable expectations. The reflection is needed to name what we will have to deal with in architecture. Architecture is not a stable sphere, and as other disciplines is subject to processes of change, which result from the specificity of the time. We need to be aware of the consequences these processes could cause. I located them in six general fields: 1.) Transformation of the tool traditional tools - set of singular, autonomous, mono-functional devices, which together make the environment; computer - one tool consisting of non-autonomous internal and external units, multifunctional; itself it is the environment, system; 2.) Transformation of the medium. As the medium is the message (M.McLuhan), so the essence of media is transmission. Traditional transmission in architectural design is direct (transmission is equivalent to recording, notation), computer based transmission is indirect (transmission is not equivalent to recording); 3.) Transformation of perception, imagination and thinking. Perception - in the process of design directly relates to media Indirect transmission - causes also rupture in direct relation between record and perception (mainly in modelling); simulated object is a stage in the process. Imagination, thinking - influenced with perception, with data transmitted from the medium - can be seen as inspiration; 4.) Transformation of cooperation and communication. It is to be done by elimination of some of intermediate stages in the design process and use of multimedial communication systems (Internet); 5.) Transformation of methodology. Same as in 4 with the possibility of simultaneous shifting in the hierarchy of design stages - almost full reversal of the process possible (regardless of individual methodology) - if needed of course; 6. Transformation of architecture itself. This concerns very deeply point 3 - and it rooms that natural consequences of the changes in perception, imagination and thinking should result in the new understanding of architecture - not as electronic methaphone, but as a sphere relevant (?!) to the vision of the world, which, as we see, is dramatically changing. The basic issue to accept is that this vision of the world should be interpreted individually. Personally.

doi https://doi.org/10.52842/conf.ecaade.1995.395
summary Basis issues concerning media need redefining, because new media should not be perceived and approached according to traditional conventions. Present understanding of a medium as a mean of linear transmission, with the primary role of sender is no more sufficient, is too simple. The possibility of mutual and multidirectional communication in the real time makes the distinction between sender and receiver not so clear. The roles are effacing, but actions, processes are not. When receiver becomes sender, the process of receiving is always distinct from sending. The importance of the process, the attention must move towards a temporal process of transmitting of the receiving. When the process changes, the message (even when ´only´ its form) changes, receiving changes because it is an active action. This paper is the collection of ideas for discussion.

doi https://doi.org/10.52842/conf.ecaade.1994.x.o5l
summary Architectural design is always concerned with form to things. It is the sphere or action where meanings are to be expressed and further on - received (by a receiver), felt, understood. "Meanings" mean not only rational information. The matter is to reach the essence and to master ways appropriate to expose and interprete it. Quality of the form decides whether architectural or any work is worth attention or not and to what degree. Form is an attribute of a thing. It is form that "speaks". This linguistic metaphore shows one of natural, inborn features of things and states. However, questions appear: 1. Does everything have form? 2. Is the form an objective term? 3. What limitations of the definition of the form to accept- if any? The friendly environment for creating form consists of conscious intentions plus open mind. Rules are certain, but liquid. Every formal communication system may be widened individually. The only limitation is to be received according to intentions. So, incredibly, the infinite number of combinations, even within one system, may be possible.

summary The paper presents the work in progress: formal experiments in computer modelling, accenting a certain shift approaching the computer - creation, not just modelling (simulating). Two main approaches to architectural computing are formulated: creative and simulative, where computer creation involves and enables quick formal synthesis, and where simulation requires analysis. The attention is paid on creation. This paper as well as the research project on abstract modelling is sponsored from the Polish Committee of Scientific Research.

summary The sphere of computing, in general, is the sphere of confusion. First, computers', thanks to (or because o) the indirect way of communicating "with" them, have not become yet the obvious and natural extension of human abilities - as TV set, radio or cars already have. It is probably because of the feeling, that they are, more or less, for specialists and that they require special knowledge or skills. In a way it is true, but surely it will change within a few years, when they become everyday tools of education at schools or just toys for children. Second, there is also the feeling or wish, that every computer is able to do everything we want - from, lets say, writing a letter, washing the dishes to very complex things as, for example, designing architecture. This is the dream of universal artificial intelligence, which should be a perfect servant, which not only listens to, but also predicts our wishes.
