The colour to knows the project ideas. The drawings of Giuseppe Damiani Almeyda
No full textGiuseppe Damiani Almeyda is insert into a historical context in which the issue of colour is living a phase of discovery and awareness. Author of numerous architectural works of international attention, arrives in Palermo in 1859, first like engineering of Civil Engineering to become a professor at the Faculty of Engineering. In the XIX century a lot of researchers of psychology, physics, optics, art and architecture are involved in meticulous research that could explain the reasons of colour, its alteration, the complementary compositions, the diagrams, the optical cones, its applications in the Greek and Roman culture. Thus, high-sounding names such as Thomas Young, James Clerk Maxwell, Wolfgang Goethe, Philipp Otto Runge, Michel Eugene Chevreul, Hermann Von Helmoholtz, Albert Henry Munsell are placed side by researchers of art and architecture as Schinkel, Hirtoff, von Klenze, Labrouste Durand and others. The crisis of Neoclassicism of Winckelmann, as a result of the new truth of colour of Selinunte Archaeological, contrasts with the study and use of polychromy in arts and architectures and Giuseppe Damiani Almeyda represents the architect that, more than others, in the Sicilian context, elaborates a wide repertoire of design drawings where the use of colour is strongly used consciously and mindfully thanks to the studies that were propagating in the contemporary culture of the time. The analysis of this gallery of drawings, rich and of inestimable beauty, will allow to identify what was the awareness and, therefore, the application idea of the colour in the author's thought, uncovering a cultural thinking of the time that embraces most of the contemporary architecture of the city of Palermo
Giuseppe Damiani Almeyda: design drawings compared
No full textGiuseppe Damiani Almeyda is among the most important designers, architects, engineers and designers at the end of '800. He has participated in numerous architectural competitions, both at Palermo in Sicily and again in Italy. He has conducted numerous studies on the identification of significant types of construction from coffee house to the shrines cemeteries, the decorative detail to the urban study on a large scale. Of course He is remembered in our city, especially as the designer of the Politeama, an imposing structure that dominates the central square of Palermo.
Very old city, whose roots, evidenced by the presence dating back to the Punic, have never found a break until the present day, offering a repertoire of great architectural prestige and international reputation. Moreover, capital, enjoys a privilege that few other cities can boast: it has two of the most important theaters in the history of Architecture: the Politeama and the Teatro Massimo.
And our dear Almeyda participated in both competitions, winning one and losing the second. But what were the real reasons why he did not win the second project? Perhaps the town is terrified of being left with a certified copy of the already made Politeama? Or, participation in the race by Giovan Battista Filippo Basile unquestionably compromised the expert advice? Or perhaps, again, the second project did not meet in style, beauty and greatness, the grandeur of the former?
These and more are the questions we have approached the study of two extraordinary projects proposed architectural competitions with only one signature, but hides itself, strange stylistic mechanisms but also social, historical, political
Drawings for engineering
No full textIn the representation of knowledge can not miss all those geometric, static, functional, and specialized
notions in infrastructures that characterize the shape of a Civil Engineer. We take this opportunity to show
how complex the representation of a hydraulic overflow, how bold is the company wanting to bring the cross
sections, the view from above, the longitudinal section. And, yet how essential is the knowledge of
descriptive geometry to determine the intersections of complex surfaces, the application of engineering has
great feedback.
An engineer must know how to read and know how to make a drawing, must learn to identify the main
characteristics, must be able to focus on the goals and be able to identify the reading of the representation of
another author. An engineer must be able to express in terms of own project idea without has any limits of
freedom of thought. Sometimes, in fact, a drawing doesn’t have the fundamental informations about the
representation and that is the limit of the project.
This study intends to show some drawings of civil works project requiring the knowledge and understanding
of the fundamentals of descriptive geometry, without which the expressive potential of the author would
inevitably be compromised
Tamarix arborea var. arborea and Tamarix parviflora: Two species valued for their adaptability to stress conditions
No full textThe choice of stress resistant and highly adaptable species is a fundamental step for landscaping and ornamental purposes in arid and coastal environments such as those in the Mediterranean basin. The genus Tamarix L. includes about 90 species with a high endurance of adversity. We investigated the water relations and photosynthetic response of Tamarix arborea (Sieb. ex Ehrenb.) Bge. var. arborea and T. parviflora DC. growing in an urban environment. Both species showed no evidence of drought or salt stress in summer, and appeared to follow two strategies with T. arborea var. arborea investing in high carbon gain at the beginning of the summer, and then reducing photosynthetic activity at the end of the season, and T. parviflora showing lower but constant levels of photosynthetic activity throughout the vegetative season. For landscaping and ornamental purposes, we suggest T. arborea var. arborea when a fast-growing, high-cover species is necessary, and T. parviflora when less-invasive species are required
Architectural library. Dioscuri Temple in Agrigento
No full textThis paper presents the synthesis of research about the ICT solution for cultural heritage through the innovative
technology of representation and survey. One objective was to identify a method of processing data for
knowledge, dissemination and preservation of the asset. Historical analysis, surveying, photogrammetry and laser
scanner, the processing of survey data and modelling are all focused to the same final purpose. The methodology
developed for this application framework becomes adoptable in General for Cultural Property, which become in
turn the protagonists of 3D WebGIS
Restituzioni omografiche di finte cupole: la cupola di Santa Maria dei Rimedi a Palermo
No full textNel vasto repertorio siciliano delle prospettive solide, un ruolo di spicco
è ricoperto da un esempio unico di realizzazione di finta prospettiva di
cupola sferica su copertura ad arco ribassato, ricavata sull’incrocio del
transetto con la navata centrale nella chiesa di Santa Maria dei Rimedi
a Palermo.
L’unicità di quest’opera sta nella geometria reale della cupola ribassata.
Infatti gli esempi più diffusi di finte cupole in Sicilia sono realizzati
su soffitti piani lignei o in calcestruzzo.
In Appendice 1 si potrà consultare il repertorio delle finte cupole
esistenti in Sicilia per la cui stesura ci si è avvalsi degli studi condotti
dall’architetto Giuseppe Ingaglio nell’ambito della sua tesi di dottorato
che ha indagato gli esempi di finte cupole in Sicilia e Malta.
Soltanto la restituzione grafica del rilievo, attraverso anche la scrittura
di algoritmi per la costruzione di traformazioni geometriche, ha disvelato
la sua geometria reale mai rappresentata nell’iconografia storica poiché
sovrastata da una struttura lignea ad otto falde.
Il rilievo è stato realizzato attraverso l’uso delle tecniche Image Based
Modelling (IBM), Structure from Motion (SfM) e contemporaneamente
attraverso l’uso di uno scanner laser FARO a differenza di fase.
Il rilievo con laser scanner è stato condotto per disporre di un modello
di cui si aveva l’accuratezza metrica grazie al quale sarebbe stato
possibile verificare l’attendibilità metrica del modello IBM attraverso
un confronto su Cloud Compare. La sovrapposizione dei modelli e il
loro allineamento è stato fatto solo allo scopo di verificare che il profilo
geometrico della cupola, generato dal modello IBM, fosse perfettamente
coincidente con quello della nuvola dei punti.
Una volta generata e indagata la geometria della volta, è stata condotta
una ricerca sui trattati che potesse fornire delle indicazioni di
massima su come queste finte prospettive si realizzavano, quali fossero
i criteri geometrici e gli accorgimenti costruttivi e dove si individuava
il punto di osservazione.
La trattatistica analizzata non ha fornito indicazioni precise operative
su casi come il nostro, tuttavia è stata adattata la trattatistica che affronta
il caso della finta prospettiva di una cupola sferica con tamburo e cupola
di chiusura su soffitto piano. Un elemento determinante in questa fase è
stato quello di disporre del punto di osservazione individuato nello spazio
interno della navata centrale. Questo punto è, infatti, individuato sul
pavimento del corridoio centrale che porta all’altare, attraverso un solco
circolare di circa 10 cm di diametro ricavato sul marmo di rivestimento.
Infine, come corollario alla ricerca condotta, è stato riportato lo studio
geometrico della restituzione di una sfera in prospettiva (in Appendice 2)
Smart survey methodologies for the digitization of architectural drawings. The maps of some convents located in the city of Parma, drawn by Giuseppe Cocconcelli in 1811
No full textThis paper regards the field of digitization of archival documentation, with particular attention to the historical iconographic apparatus related to the specific sector of architecture. The operation of dematerialization, essential for the preservation, protection, management, dissemination, and valorization of this heritage, plays a key role in the complex knowledge process of an architectural organism. By illustrating the experimentation carried out on an unpublished collection of survey drawings, drawn by Giuseppe Cocconcelli in 1811, related to some religious structures located in Parma, a reflection on the potential of survey methodologies for the digital documentation of graphic elaborates will be presented. The method adopted represents a possible solution for the digitization of documents that require a digital reproduction that is geometrically correct
