Resumen: El empleo de tecnología de simulación por parte de la Armada Argentina, resulta sumamente necesario para el adiestramiento de personal militar y civil. En los últimos años la Armada Argentina ha venido trabajando fuertemente en estos temas, vinculándose con institutos de investigación y universidades nacionales mediante convenios de colaboración, que han derivado en el desarrollo de tres simuladores de entrenamiento para diversas escuelas de la Armada: El simulador Melipal en operación en Puerto Gral. Belgrano, el simulador de periscopio SIPER instalado en la Escuela Nacional de Submarinos y Buceo, y el simulador de embarcación pesquera Melipal-P instalado en la Escuela Nacional de Pesca. En este contexto, se presenta un estudio sobre la aplicación de nuevas tecnologías para el mejoramiento y actualización de los simuladores de entrenamiento antes mencionados. Más concretamente se propone una serie de herramientas graficas para el desarrollo de entornos virtuales de entrenamiento, capaces de recrear todas las situaciones que se le presentan al operario a la hora de recibir la capacitación. Para esta presentación se considera el sistema Melipal como caso particular de aplicación.

Virtual Reality has greatly evolved between 1940s and 1990s. Since then, it has been implemented in multiple research and knowledge areas, the most recognized being the entertainment industry. In order to establish the state of Virtual Reality and get an idea of its prospects, 537 scientific documents have been reviewed, applying search criteria, more specifically, Virtual Reality applied to education. A bibliometric analysis was realized based on summarizing each document, as well as its keywords and trends, then proceeding to categorize each one, according to the field of application. It was found that Virtual Reality is having relevance in medicine and training area, due to the ability to simulate difficult situations and above all, specific conditions raised by instructors. The future of Virtual Reality as a tool to train professionals in multiples areas is promising.

The possibilities of using the new software of virtual reality NeoTrie VR (or Neotrie) to teach geometry to children aged 11-14 years old are presented. This software is tested for the first time as a part of math lessons at a School in Żernica (Poland). The use of Neotrie has made it easier to eliminate some of the problems faced by the pupils in the early stages of geometry learning. Moreover, the participating students solve geometric tasks more quickly, compared with previous years, especially those that require spatial imagination and those with a higher degree of difficulty. Since the program has been implemented, pupils are more active and prone to cooperation, and to formulate conclusions. Neotrie turns out to be a useful tool for teaching Geometry, it helps students to better organize their geometric knowledge in a ludic way, to increase their spatial reasoning and creativity.

2014 XVI Symposium on Virtual and Augmented Reality, 2014

Virtual Reality is becoming a mature technology field. To understand its origins and foresee strategies, a study on the last decade of papers published in the Brazilians´ most prominent symposium (the SVR -Symposium on Virtual and Augmented Reality) has been carried out. Papers were classified according to language, international participants, areas and subareas of application and related technologies. Although oversees participants has proven not constant, papers published in English has proven stable to SVR editions. The study also shows that health related applications have received most of the attention although techniques and tools proposal have raised the most recently which could be related to the low-level programming languages and frameworks preferences. The number of Augmented Reality papers has grown steadily and a great variety of underlying knowledge fields (such as 3D interaction and real-time simulation) are persistent topics of interest. An expected shift from VRML to other 3D Web technologies have already happened but there are just a few research papers devoted to formulative, evaluative or descriptive approaches. Data show that by improving the research budget to the area could impact productivity; a centralized database of publications would facilitate recovering and analyzing past contributions and; that enforcing more scientifically rigorous and English-written papers could raise the quality and visibility of Brazilians´ research in VR.

Proceedings of the XVIII Conference of the Iberoamerican Society of Digital Graphics - SIGraDi: Design in Freedom, 2014

This paper presents an experimentation of the use of 4D technology in order to generate a simulation. An approach will be made about this technology, as well as its evolutionary process, and how the graphical representation is changing and used in various applications. It will be shown the advantages fourth dimension can bring to the realization of architectural projects, as well as some advice for the process will be really efficient.

In line with the conference title ?Full-scale Modeling in the Age of Virtual Reality? the participants will particularly concern themselves with the relationship of physical 1:1 simulations and VR. If the assumption holds true that those creating architecture provide of a higher degree of affinity to physical than to virtual models and prototypes will be subject of discussions. Furthermore, the participants will devote some time to issues such as the integration of model-like ideas and built reality thus uncovering any such synergy-effects. In times characterized by the growing ?architectural criticism? to the same extent as by the helplessness of the anonymous user the communication process between contractors, planer and users gains in importance. If communication is successful will not only depend on the quality of the project but also on the means of conveyance, e.g. visualizing or model representation. Can planning evaluation be effectively supported by virtual reality (VR)?

Virtual in virtual, discretization in discretization: shape and perception in parametric modelling for renewing descriptive geometry in Proceedings of ICGG 2010 14TH International Conference on Geometry and Graphics, Naomi Ando et alii, 2010, Kyoto, Japan, pp. 129-130, 2010

Although architecture and design are one of the first expressions of man and his culture, time has transformed the relationship between man, environment and representation and the recent digital revolution has changed the way we study and perceive the geometry in architecture: multimedia, interactivity, modifiability allow the user to analyze, from different angles, the model, centre of designing interest since Galileo’s scientific method. The combination between digital images and mathematics brings up a profound renewal to descriptive geometry as well as to his research and education, too often reduced in between the two extremes of an anachronistic classicism or an innovative computerization without historical background. An integration is actually possible though, and a study of the relations between visual perception and shape in designing is presented as an example. Optical refinements that affected architecture in western culture since the Classical style find new applications thanks to the birth of science, from Quadraturism in eighteenth century to Esher’s deceptions, till the transactionalism research group, with their studies based on the virtual character of the images. Therefore, descriptive geometry emerges as an instrument able to provide rules and keys for interpreting the relationship between architecture and man, and the computer screen perfects the eye-brain telescope with an additional lens that increases the power of definition and representation. The proposed example is the famous Ames room, constructed from his virtual appearance so that it appears to be, from the front, an ordinary parallelepiped-shaped room, but distorted in reality, so as to create an optical illusion on measure. There are two illusions associated with the Ames Room. First the room appears parallelepiped when viewed monocularly from a special viewing point; second, within an Ames Room people or objects can appear to grow or shrink when moving from one corner to the other. It is possible to study this case with an experimental approach, exploiting the developments of parametric modelling that allow to clearly see the logical process and simply ensure dynamic solutions. Through a graphic-algorithm editor as Grasshopper for Rhinoceros, once designed the logic of the experiment, it is possible to vary the parameters so as to test the range of validity of the basic hypotheses. In Grasshopper, the representative action is fundamentally defined by parameters and algorithms: values are required in input and the result is an output of parameters, generally used as input data for further commands, so forming a network of nodes and connections. It’s a visual aid for scripting, so his interface contains a number of different elements, most of which should be very familiar to Rhino users. Through parametric modelling, used in an unusual way as an analytical tool, geometry is described in a unexplored dynamicity that founds a new experimental process, based on observation and monitoring of parameters, a marriage between research and application that makes them both rich and happy.

To construct virtual models of the pre-Hispanic archaeological sites of Bonampak, Cacaxtla and Suchilquitongo for their exploration in real time in the immersive virtual reality system of the National University of Mexico (UNAM), we used different methodologies and obtained results with different levels of precision. The relation between these characteristics and their potential for research, teaching and documentation of historical architecture is explained. The three sites have a good amount of mural painting which make them particularly interesting for several disciplines such as history of art, conservation, and archaeology. Nevertheless, each use has specific requirements that the 3 models cover in different ways.

Dagstuhl Seminar Proceedings, 2008

From 1st to 6th June 2008, the Dagstuhl Seminar 08231 Virtual Realities was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. Virtual Reality (VR) is a multidisciplinary area of research aimed at interactive human-computer mediated simulations of articial environments. Typical applications include simulation, training, scientic visualization, and entertainment. An important aspect of VR-based systems is the stimulation of the human senses typically sight, sound, and touch such that a user feels a sense of presence (or immersion) in the virtual environment. Dierent applications require dierent levels of presence, with corresponding levels of realism, sensory immersion, and spatiotemporal interactive delity. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. Links to extended abstracts or full papers are provided, if available.

A unidade curricular permite ao aluno do mestrado de arquitetura personalizar a prática do desenho e do desenho arquitetónico, num processo experimental e disruptivo, que interseta observação, criatividade e representação. Nas vanguardas da cultura arquitetónica, o desenho de composição e expressão de atmosferas contribui para pensar a ontologia da atividade projetual do arquiteto, nas suas espessuras de sentido e significado. Os blocos programáticos correspondem a desenhos temáticos, que organizam a prática dos conteúdos em relação às escalas da arquitetura (espaços interiores e exteriores: compartimento, casa, prédio, quarteirão, bairro, cidade, paisagem, território). A metodologia de ensino formaliza os objetivos da aprendizagem num processo sucessivo de observação, análise e produção de desenhos. Da identidade do espaço à identidade do desenho do arquiteto, a unidade curricular de Desenho de Atmosferas Arquitetónicas sublinha a imprevisibilidade da experimentação gráfica, a amplificação do repertório de atmosferas espaciais e a síntese do paradigma da simplicidade.

In the construction of a model, architectural drawing is not so much ‘representative drawing’ as ‘constructive drawing’. Scale and measure are fundamental criteria for interpreting and representing the parts of a unicum linked together in a hierarchical or interconnected relationship. This gives rise to the entire asset of a project, where various disciplines, or spheres of knowledge, integrate to generate models that make it possible to simulate its construction and predict its impact. For digital design, the computer screen is like a window opening onto the model’s virtual space that allows us to observe and interact with it while moving and modifying it. Virtual reality, immersive and mixed, creates new dimensions that animate the model, and from these dimensions, the complexity of the multiscalar project unfolds as the result of multidimensional thinking, for a creative, multidirectional, anti-dogmatic model.
