Computer Aided Drawing

Resulta sorprendente que los dos programas de dibujo por ordenador más extendidos no permitan obtener una perspectiva militar a partir de un modelo tridimensional. Ahora bien, podemos superar esta limitación sometiendo una axonometría ortogonal a una transformación geométrica tan sencilla como una afinidad ortogonal, es decir, un simple alargamiento, para obtener una perspectiva militar.

The Alliance Framework makes it easier and more accessible for local organizations to create and share documentation concerning locally significant historic and cultural resources with the general public. Traditional forms of documentation, such as historic texts, photographs and maps, are typically reserved in archives that are not easily accessible. This, in a way, restricts the public from connecting with the past. The Alliance Framework guides users through the creation of emerging forms of documentation, specifically three-dimensional photogrammetric models and computer aided line drawings, as a way of complementing traditional documentation sources. Both forms of documentation are then formatted and organized for dissemination through an online exhibit powered by Omeka, an online digital archiving platform. This interactive experience provides visitors with a more comprehensive understanding of the site they are researching in an easily accessible, engaging way. By taking advantage of technological advancements, local cultural resources can be highlighted in the same way larger, more well-known state, heritage sites are, allowing them to be experienced regardless of location or physical access.

Invention of digital technology has lead to increase in the number of images that can be stored in digital format. So searching and retrieving images in large image databases has become more challenging. From the last few years, Content Based Image Retrieval (CBIR) gained increasing attention from researcher. CBIR is a system which uses visual features of image to search user required image from large image database and user's requests in the form of a query image. Important features of images are colour, texture and shape which give detailed information about the image. CBIR techniques using different feature extraction techniques are discussed in this paper.

The widespread of smart devices along with the exponential growth of virtual societies yield big digital image databases. These databases can be counter-productive if they are not coupled with efficient Content-Based Image Retrieval (CBIR) tools. The last decade has witnessed the introduction of promising CBIR systems and promoted applications in various fields. In this article, a survey on state of the art content based image retrieval including empirical and theoretical work is proposed. This work also includes publications that cover research aspects relevant to CBIR area. Namely, unsupervised and supervised learning and fusion techniques along with lowlevel image visual descriptors have been reported. Moreover, challenges and applications that emerged to support CBIR research have been discussed in this work.

In this report, I describe and demonstrate in detail my reasoning and approach to 3D-Modeling and designing the first prototype of the proposed Left-Handed Friendly Foldable Integrated Desk Chair, along with technical drawings attached in the end of the report. These are my personal design notes that I submitted at the end of the Integrated design course in the department of Mechanical Engineering at Korea University.

The search for material referring specifically to documentation issues in the world of heritage conservation is a difficult one. If, moreover, this research were restricted to the documentation of mural paintings, it would be truly impossible due to the lack of references. It is therefore necessary to refer to codes and norms relating to the architectural context and to identify methodological affinities. Indeed, principles and methods of documentation are never confined to a particular type of heritage. (...)

SPACE International Conference 2021 on Computer Aided Design in Architecture and Urban Planning will be held in London (online) on 26-27 February 2021. SPACE Conferences always attract a substantial
number of participants from all over the world. Thus, the Conference establishes an ideal platform to recent advances and research results in the fields of computer aided design, architecture and urban planning. The scientific quality of the Conference provided by SPACE International Advisory Board and the variety of the topics are the most important reasons behind this success of the series.

SPACE Studies of Planning and Architecture invites researchers, planners, architects and social partners to share their knowledge and experiences from their fields of expertise according to the topics of the Conference, but not limited to.

En algo más de diez años, el Dibujo Asistido por Ordenador (DAO) ha pasado de tener una presencia muy reducida en los estudios de arquitectura de nuestro país a ser el medio de expresión gráfica habitual en la profesión. Esta evolución rapidísima ha sido posible porque las órdenes, la interfaz de usuario, los manuales y los archivos de ayuda de los programas más extendidos han sido traducidos al castellano. El fenómeno lleva aparejados dos efectos de gran alcance. Por una parte, ya sea por la gran velocidad de desarrollo e implantación de estos programas, ya sea por las presiones comerciales que acompañan a los lanzamientos de cada versión, ya sea por
otras causas, algunos aspectos de las traducciones parecen haber sido resueltos de forma apresurada. Por otra, el efecto expansivo de estas traducciones es enorme. Los términos, acertados o espúreos, que emplean los programas, pasan a los autores de manuales independientes y a los profesores de DAO, y de ellos a los alumnos y profesionales. Por tanto, estos traductores anónimos desempeñan un papel central en la renovación del vocabulario geométrico de los arquitectos e ingenieros. Muchas de las opciones empleadas en estas traducciones son irreprochables; unas pocas son incluso brillantes. Pero junto a estos aciertos, aparecen también algunos errores que en ocasiones se han extendido entre las profesiones técnicas, y que llegan a convertir los manuales y archivos de ayuda en ininteligibles y pasan al vocabulario geométrico empleado por arquitectos e ingenieros, creando la confusión y dificultando la comunicación entre los técnicos.
El papel de los profesores de DAO en este proceso es secundario, pero de todas formas importante. No pueden evitar las malas traducciones, pero pueden intentar colaborar lo menos posible en su propagación. Con esta intención, nos proponemos analizar algunos aspectos de estas traducciones, señalando algunos de los errores de traducción más llamativos. No tendría sentido aquí dar un carácter exhaustivo a nuestro estudio; quede claro, por tanto, que los pasajes citados son meros ejemplos. También sería imposible referirnos a todos los programas y utilidades de DAO disponibles en el mercado y, menos aún, a las de dominio público, por lo que el estudio se centrará en los dos programas más extendidos.

According to UNESCO "Earthen architecture is one of the most original and powerful expressions of our ability to create a built environment with readily available resources. It includes a great variety of structures, ranging from mosques, palaces and granaries, to historic city centres, cultural landscapes and archaeological sites" (WHEAP, 2007). This contribution looks at developing effective methods for recording earthen historic structures for their rehabilitation and preservation using the Kuño Tambo church in Peru, which is a Peruvian national historic site that requires serious rehabilitation work, as a case study. This project describes the compilation of an effective metric record of the "state-of-conservation"-"as found" of wall paintings in this important and remote building using a toolbox of different 'off-the-shelf' heritage recording techniques. This approach was applied by Carleton Immersive Media Studio (CIMS), as part of the Earthen Architecture Initiative of the Getty Conservation Institute (GCI).
