title	Visual navigation of large environments using textured clusters
source	Proceedings 1995 Symposium on Interactive 3D Graphics, pp. 95-102, June 1995
summary	A visual navigation system is described which uses texture mapped primitives to represent clusters of objects to maintain high and approximately constant frame rates. In cases where there are more unoccluded primitives inside the view- ing frustum than can be drawn in real-time on the workstation, this system ensures that each visible object, or a cluster that includes it, is drawn in each frame. The system supports the we of traditional "level-of-detail" representations for individual objects, and supports the automatic genera- tion of a certain type of level-of-detail for objects and clusters of objects. The concept of choosing a representation from among those associated with an object that accounts for the direction from which the object is viewed is also supported. The level-of-detail concept is extended to the whole model and the entire scene is stored as a hierarchy of levels-of-detail that is traversed top-down to iind a good representation for a given viewpoint. This system does not assume that visibility information can be extracted from the model and is thus especially suited for outdoor environments.

title	SDM: Selective Dynamic Manipulation of Visualizations
source	Proceedings of UIST‘95, ACM Symposium on User Interface Software and Technology, Pittsburg. 61-70
summary	In this paper we present a new set of interactive techniques for 2D and 3D visualizations. This set of techniques is called SDM (Selective Dynamic Manipulation). Selective, indicating our goal for providing a high degree of user control in selecting an object set, in selecting interactive techniques and the properties they affect, and in the degree to which a user action affects the visualization. Dynamic, indicating that the interactions all occur in real-time and that interactive animation is used to provide better contextual information to users in response to an action or operation. Manipulation, indicating the types of interactions we provide, where users can directly move objects and transform their appearance to perform different tasks. While many other approaches only provide interactive techniques in isolation, SDM supports a suite of techniques which users can combine to solve a wide variety of problems.

title	An environment for real-time urban visualization
source	Proceedings of the Symposium on Interactive 3D Gra hics, Monterey, CA
summary	Drawing from technologies developed for military flight simulation and virtual reality, a system for efficiently modeling and simulating urban environments has been implemented at UCLA. This system combines relatively simple 3-dimensional models (from a traditional CAD standpoint) with aerial photographs and street level video to create a realistic (down to plants, street signs and the graffiti on the walls) model of an urban neighborhood which can then be used for interactive fly and walk-through demonstrations.The Urban Simulator project is more than just the simulation software. It is a methodology which integrates existing systems such as CAD and GIS with visual simulation to facilitate the modeling, display, and evaluation of alternative proposed environments. It can be used to visualize neighborhoods as they currently exist and how they might appear after built intervention occurs. Or, the system can be used to simulate entirely new development.

title	Computer Graphics for the Study of Colour Science
source	CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 267-273
summary	There is an absolute dependence between the professional colour culture and the sphere of professional architectural tasks. From the skill to know how to handle brush up to the skill to convey one's own conception to the customer. Colour sketch, polychrom model, means of computer aided design, colour schemes and diagrams, are the means, which modern architect must wield. Actually an architect must think "by colours" from the very beginning of designing and must use colour as a compositional expedient. Architectural colour theory gives the students of the architectural department fundamental rules of colour science and methods of their practical utilization. But today the real designing demands the wider utilization computer of the graphic. There are a lot of remarkable graphic packages, which help architects to wield vector-mode graphic display and roster- mode graphic display, to work with colour and shape. That is why it is necessary to teach students to use the possibility of computer designing in the field of architectural colour science. This task determines the general matter and direction of teaching programme, defines the character and the way of its composition, The teaching programme is adapted for using the graphic package "Corel DRAW-5.0". Students work with a simple set of software tools "Corel DRAW" and at the same time acquire habit of working with the graphic package and decide problems of plane and volume colour simulation. The main practical tasks - colour on perception, psychological influence of colour people, colour harmonies, are performed by the way of "colour modelator". With the help of uncomplicated transformations it helps to receive a necessary set of simple figures for colour exercises.

title	Computing And Manipulation In Design - A Pedagogical Experience Using Symmetry
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	The concept of symmetry has been usually restricted to bilateral symmetry, though in an extended sense it refers to any isometric transformation that maintains a certain shape invariant. Groups of operations such as translation, rotation, reflection and combinations of these originate patterns classified by modern mathematics as point groups, friezes and wallpapers (March and Steadman, 1974). This extended notion represents a tool for the recognition and reproduction of patterns, a primal aspect of the perception, comprehension and description of everything that we see. Another aspect of this process is the perception of shapes, primary and emergent. Primary shapes are the ones explicitly represented and emergent shapes are the ones implicit in the others (Gero and Yan, 1994). Some groups of shapes known as Semantic Shapes are especially meaningful in architecture, expressing visual features so as symmetry, rhythm, movement and balance. The extended understanding of the concept of symmetry might improve the development of cognitive abilities concerning the creation, recognition and meaning of forms and shapes, aspects of visual reasoning involved in the design process. This paper discusses the development of a pedagogical experience concerned with the application of the concept of symmetry in the creative generation of forms using computational tools and manipulation. The experience has been carried out since 1995 with 3rd year architectural design students. For the exploration of compositions based on symmetry operations with computational support we followed a method developed by Celani (2003) comprising the automatic generation and update of symmetry patterns using AutoCAD. The exercises with computational support were combined with other different exercises in each semester. The first approach combined the creation of two-dimensional patterns to their application and to their modeling into three-dimensions. The second approach combined the work with computational support with work with physical models and mirrors and the analysis of the created patterns. And the third approach combined the computational tasks with work with two-dimensional physical shapes and mirrors. The student’s work was analyzed under aspects such as Discretion/ Continuity –the creation of isolated groups of shapes or continuous overlapped patterns; Generation of Meta-Shapes –the emergence of new shapes from the geometrical relation between the generative shape and the structure of the symmetrical arrangement; Modes of Representation –the visual aspects of the generative shape such as color and shading; Visual Reasoning –the derivation of 3D compositions from 2D patterns by their progressive analysis and recognition; Conscious Interaction –the simultaneous creation and analysis of symmetry compositions, whether with computational support or with physical shapes and mirrors. The combined work with computational support and with physical models and mirrors enhanced the students understanding on the extended concept of symmetry. The conscious creation and analysis of the patterns also stimulated the student’s understanding over the different semantic possibilities involved in the exploration of forms and shapes in two or three dimensions. The method allowed the development of both syntactic and semantic aspects of visual reasoning, enhancing the students’ visual repertoire. This constitutes an important strategy in the building of the cognitive abilities used in the architectural design process.

source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 113-124
summary	This paper depicts the evolution of the research done at the Sasada Laboratory (Osaka University) in the fields of Architectural and Urban related Computer Simulations. This research led to the birth of what we call the "Open Development Environment" (ODE). ODE is presented in this paper through a simple example. In this example, four teams cooperate to produce the database for a simple twin tower complex. The database is kept very simple and the protocol of communication among the different teams is a new computer language called VU (Vee-You). VU was conceived and developed by Claude Comair for the specific purpose of defining architectural and urban objects.

title	HoloSketch: A Virtual Reality Sketching/Animation Tool Special Issue on Virtual Reality Software and Technology
source	Transactions on Computer-Human Interaction 1995 v.2 n.3 pp. 220-238
summary	This article describes HoloSketch, a virtual reality-based 3D geometry creation and manipulation tool. HoloSketch is aimed at providing nonprogrammers with an easy-to-use 3D "What-You-See-Is-What-You-Get" environment. Using head-tracked stereo shutter glasses and a desktop CRT display configuration, virtual objects can be created with a 3D wand manipulator directly in front of the user, at very high accuracy and much more rapidly than with traditional 3D drawing systems. HoloSketch also supports simple animation and audio control for virtual objects. This article describes the functions of the HoloSketch system, as well as our experience so far with more-general issues of head-tracked stereo 3D user interface design.

title	Sketching as a Solid Modeling Tool
source	Third Symposium on Solid Modeling and Applications. C. Hoffmann and J. Rossignac. Salt Lake City, ACM: 313-321
summary	This paper describes 'Quick-sketch', a 2d and 3d modeling tool for pen based computers. Users of this system define a model by simple pen strokes drawn directly on the screen of a pen-based PC. Lines, circles, arcs, or B-spline curves are automatically distinguished, and interpreted from these strokes. The system also automatically determines relations, such as right angles, tangencies, symmetry, and parallelism, from the sketch input, These relationships are then used to clean up the drawing by making the approximate relationships exact. Constraints are established to maintain the relationships in further editing. A constraint maintenance system, which is based on gestural manipulation and soft constraints, is employed in this system. Several techniques for sketch based definitions of solid objects are provided as well, including extrusion, surface of revolution, ruled surfaces and sweep. Feat ures can be sketched on the surfaces of 3d objects, using the same 2d- and 3d techniques. This way, objects of medium complexity can be sketched in seconds. The system can be used as a front-end to more sophisticated modeling, rendering or animation environments, serving as a hand sketching tool in the preliminary design phase.

title	Base de datos de la arquitectura moderna de la ciudad de Maracaibo 1920-1990 [Database of the Modern Architecture of the City of Maracaibo 1920-1990]
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 133-139
summary	Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

summary	Traditional ways of an aesthetic expression like hand drawing and renderings, painting and artistic graphics, are now enriched by computer multimedia techniques. The multimedia techniques are used in the Department of Architecture of Warsaw University of Technology for presentation of student´s design. The connected media, like computer renderings, animations and sound are used to express sophisticated aesthetics intentions by students in their conceptual designs. In the past two years, three inexpensive multimedia editors were tested on PC´s: Tempra Media Author, HSC Interactive and Multimedia Director 4.0. The most convenient, but not excellent, for our purposes was The Tempra Media Author. Several aspects of multimedia presentation were analyzed and some suggestions for the future were done.

title	Efficient rendering of trimmed NURBS surfaces
source	Computer-Aided Design, Vol. 27 (7) (1995) pp. 509-521
summary	An algorithm for the interactive display of trimmed nurbs surfaces is presented. The algorithm converts the nurbs surfaces to Bézier surfaces, and nurbs trimming curves toBézier curves. It tessellates each trimmed Bézier surface into triangles, and renders them using the triangle rendering capabilities common in current graphics systems. Itmakes use of tight bounds for the uniform tessellation of Bézier surfaces into cells and it traces the trimming curves to compute the trimmed regions of each cell. Thisoperation is based on the tracing of trimming curves, intersection computation with the cells, and triangulation of the cells. The resulting technique also makes use of spatialand temporal coherence between successive frames for cell computation and triangulation. Polygonization anomalies such as cracks and angularities are avoided as well. Thealgorithm can display trimmed models described using thousands of Bézier surfaces at interactive frame rates on high end graphics systems.

title	Interactive Computer Rendering
source	Architectural Research Quarterly Vol 1 No1. EMAP, London
summary	Interactive Rendering combines the geometrical precision of classical computer graphics with the representational freedom of a paint program. It is more sympathetic to the ways in which designers use images, and overcomes many of the frustrations experienced in rendering from CAD models. The scene is generated in a standard viewing application, but saved as a specially enhanced raster image. The extra information allows the Interactive Renderer to apply brushed-on rendering effects which are sensitive to the perspective of the image. Effects can be applied locally or overall, and may be overlaid, blended and erased to create complex combinations. A huge range of treatments are obtainable, both photorealistic and not.

title	Ray Tracing – New Chances, Possibilities and Limitations in AutoCAD
source	CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 121-136
summary	Realistic image synthesis is nowadays widely used in engineering applications. Some of these applications, such as architectural, interior, lighting and industrial design demand accurate visualization of non-existent scenes as they would look to us, when built in reality. This can only be archived by using physically based models of light interaction with surfaces, and simulating propagation of light through an environment. Ray tracing is one of the most powerful techniques used in computer graphics, which can produce such very realistic images. Ray tracing algorithm follows the paths of light rays backwards from observer into the scene. It is very time consuming process and as such one could not be developed until proper computers appeared, In recent years the technological improvements in computer industry brought more powerful machines with bigger storage capacities and better graphic devices. Owing to increasing these hardware capabilities successful implementation of ray tracing in different CAD software became possible also on PC machines. Ray tracing in AutoCAD r.12 - the most popular CAD package in the world - is the best of that example. AccuRender and AutoVision are an AutoCAD Development System (ADS) applications that use ray tracing to create photorealistic images from 3D AutoCAD models. These ,internal"' applications let users generate synthetic images of threedimensional models and scenes entirely within AutoCAD space and show effects directly on main AutoCAD screen. Ray tracing algorithm accurately calculates and displays shadows, transparency, diffusion, reflection, and refraction from surface qualities of user-defined materials. The accurate modelling of light lets produce sophisticated effects and high-quality images, which these ray tracers always generates at 24-bit pixel depth,"providing 16,7 million colours. That results can be quite impressive for some architects and are almost acceptable for others but that coloured virtual world, which is presented by ray tracing in AutoCAD space in such convincing way, is still not exactly the same as the real world. Main limitations of realism are due to the nature of ray tracing method Classical ray tracing technique takes into account the effects of light reflection from neighbouring surfaces but, leaves out of account the ambient and global illumination arising out of complex interreflections in an environment. So models generated by ray tracing belong to an "ideal" world where real materials and environment can't find their right place. We complain about that fact and say that ray tracing shows us "too specular world", but (...) (...) there is anything better on the horizon? It should be concluded, that typical abilities of today's graphics software and hardware are far from exploited. As was observed in literature there have been various works carried along with the explicit intention of overcoming all these ray tracing limitations, These researches seem to be very promising and let us hope that their results will be seen in CAD applications soon. As it happens with modelling, perhaps the answer will come from a variety of techniques that can be combined together with ray tracing depending on the case we are dealing with. Therefore from the point of view of an architects that try to keep alive some interest on the nature of materials and their interaction with form, "ray tracing" seems to be right path of research and development that we can still a long way follow, From the point of view of the school, a critical assimilation of "ray tracing" processes is required and one that might help to determinate exactly their distortions and to indicate the correct way of its development and right place in CAAD education. I trust that ray tracing will become standard not only in AutoCAD but in all architectural space modelling CAD applications and will be established as a powerful and real tool for experimental researches in architectural design process. Will be the technological progress so significant in the nearest future as it is anticipated?

title	Interactive Freehand Sketch Interpreter for Geometric Modelling I.16 Pen-Based Interface
source	Proceedings of the Sixth International Conference on Human-Computer Interaction 1995 v.I. Human and Future Computing pp. 561-566
summary	This paper presents a new method to deal with idea sketches for inputting geometric models at a workstation. The idea sketches are drawn on a CRT screen with a stylus pen and a tablet by designers at an initial stage of design procedures. They can keep their drawing styles at a workstation as the same manner as using a pen on paper. The system 'Sketch Interpreter' can create correct geometric models in a computer even though input idea sketches are incorrect perspectively. Data created are transferred to an advanced 3D-CAD system. The system is applied as a front-end processor for a design practice.

title	3D Digitizers for Engineering
source	Computer Graphics World, (March 1995), p. 112-115
summary	3D digitizing systems permit you to create a digital model from a physical part. The process is appealing because it can be difficult to create models of complex objects using computer tools without the aid of a 3D input device. Recreating an existing part from scratch, even with a computer, is like copying a printed page by retyping it. Although 3D digitizers are not as straightforward as a photocopy machine, the intent is the same. You can render and print a digitized model to communicate shape information, extract dimensions from it to show size information, and use the 3D database to manufacture a replica using rapid prototyping (RP) and CNC machines. You can also include the 3D model in multimedia or animation software as a learning or assembly aid. The challenge of the digitization process in manufacturing is to capture adequate detail and resolution. Adding a digitized model to a Hollywood film is often much easier than reverse engineering a part for prototyping or manufacturing. The only criteria for a movie or TV commercial is whether or not it looks good. No one from the audience measures the object to see if it meets a given tolerance. In manufacturing, RP and CNC machines require clean, complete, and accurate information. If areas on the model are incomplete or missing, it may be difficult or impossible to build the part. If edges, grooves, and features of the part are not fine and crisp, the results may be less than satisfactory. Most 3D digitizing systems are best at digitizing organic shapes such as free-form sculpted surfaces. When you see an advertisement or a catalog from companies offering digitized models, often you see objects such as human anatomy, animals, bones, skeletons, and so on. You may also see cars, trucks, motorcycles and airplanes, although they can be more difficult to digitize. Highly engineered parts, such as enclosures for electronic devices are usually the most difficult for 3D digitizers. That's why these systems aren't used widely for the reverse engineering of precision mechanical parts.

summary	The paper discusses 23 interviewed architects in practice about the role of traditional and digital sketching (human-computer interaction) in communication with the client. They were selected from 1995 to 2018 (the interval of graduation) from three different countries: the Czech Republic (CR), Slovakia (SR), Netherland (NR). To realize three blending areas that impact the approach to sketching: (I) Traditional hand and physical model studies (1995-2003). (II)Transition form - designing by hand and PC (2004–2017). (III) Mainly digital and remote forms of designing (2018–now). Interviews helped transform 31 “parameters of tools use” from the previous theoretical framework narrowed down into six main areas: (1) Implementation; (2)Affordability; (3)Timesaving; (4) Drawing support; (5) Representativeness; (6) Transportability. Paper discusses findings from interviewees: (A) Implementation issues are above time and price. (B) Strongly different understanding of what digital sketching is. From drawing in Google Slides by mouse to sketching in Metaverse. (C) Substantial reduction of traditional sketching (down to a total of 3% of the time) at the expense of growing responsibilities. (D) 80% of respondents do not recommend sketching in front of the client. Also, other interesting findings are further described in the discussion.

title	Software Environment to Support Early Phases in Building Design (SEED): Overview
source	Journal of Architectural Engineering -- December 1995 -- Volume 1, Issue 4, pp. 147-152
summary	This paper describes the overall goals of SEED, the approach taken by its developers to achieve these goals, and the subprojects that comprise the entire project. SEED aims at providing computational support forthe early design phase in all aspects that can benefit from such support. It addresses specifically architectural programming, schematic layout design, and the generation of a fully three-dimensional configuration ofphysical building components like structure and enclosure. These tasks are handled by three individual modules, SEED-Pro, SEED-Layout, and SEED-Config. A standards processor is under development tosupport standards and code checking in any module, as is an object database to store and retrieve different design versions, alternatives, and past designs that can be reused and adapted in different contexts(case-based design). Usability issues, especially the interfaces to the modules, receive special attention. Subsequent papers elaborate on these efforts in greater detail. The present paper provides an overview of theentire project and introduces shared concepts presumed known in subsequent papers.
