AB  - This paper investigates the impact of various extrinsic shooting parameters regarding change of roughness-quality of surface textures of linear objects/elements when presented in the form of unstructured photogrammetrially created point-clouds. To perform this scientifically-wise, two types of specific quality-descriptors are identified: process-quality descriptors and smoothness related quality descriptors. Then, they are precisely defined, computed and mutually correlated. It can be generally concluded that for a fixed focal length, shooting directions perpendicular to the axis of targeted object/element, station-points uniformly radially distributed around it (at a circle of 360 deg.) and obtained process-quality descriptors values that belong to satisfying /recommended ranges, the performed photogrammetric digitalization is declared highly precise and satisfyingly accurate regarding roughness /smoothness and barely prone to object-to-camera distance.
AB  - Rad istražuje uticaj različitih ekstrinzičnih parametara snimanja površina linijskih objekata /elemenata, na promenu kvaliteta njihovih tekstura sa aspekta hrapavosti u slučaju kada su one fotogrametrijski generisane u vidu nestrukturiranih oblaka tačaka. U cilju uvođenja naučne metodologije u predmetno eksperimentalno istraživanje, identifikovana su (kao relevantna) dva tipa specifičnih deskriptora analiziranog kvaliteta (deskriptori koji opisuju nivo kvaliteta softverskog/fotogrametrijskog procesuiranja digitalnih snimaka izabranog eksperimentalnog objekta /elementa i deskriptori kojima se definiše postignuti kvalitet hrapavosti tj. stepen očuvanosti glatkoće njegove digitalizovane površine). Ovi deskriptori su, potom, precizno definisani i softverskim putem izračunati. Doneti zaključci su bazirani na analizi ciljno-relevantnih korelacija prethodno dobijenih vrednosti tih deskriptora. Zaključeno je da je za nepromenljivu žižnu daljinu, pravce snimanja upravne na osu linijskog objekta-elementa koji se fotografiše, za pozicije foto-aparata i fotogrametrijske targete ravnomerno radijalno raspoređene oko te ose (po krugu od 360°), kao i za dobijene vrednosti parametara kvaliteta realizovanog fotogrametrijskog procesuiranja (process-quality descriptors values) koje su u prihvatljivom/preporučenom opsegu, sve digitalizovane površine su predstavljene oblacima tačkama čije generisanje karakterišu visoka preciznost (precision) i zadovoljavajući nivo tačnosti (accuracy) na koje neznatno utiče distanca sa koje se vrši snimanje.

AB  - The paper systematizes geometric aspects relevant for understanding design of solar systems. The systematization is based on a review of literature dedicated to various kinds of engineers, including architects, involved in a multidisciplinary process of conceptualizing, designing and realization of PV systems. The understanding of the presented geometric aspects, known as solar geometry, is important not only in terms of finding optimal orientation and most effective tilt of solar modules, but also in terms of adequate geometric modelling of façade elements of a complex shape (as specific photovoltaic modules) in order to be optimally exposed to the sun all over the year. After providing detailed explanations of the main elements of solar geometry using the tools of spherical trigonometry, the paper discusses the integration of the presented geometric concepts in the BIM environments, and refers the example of Autodesk Revit software through its sun study tool. Analysed are functionalities of all interactive components of the 3D solar path representation. A need for more explicit determination of an incidence angle of the sun rays on a tilted surface is stressed. In the conclusion highlighted is the essential knowledge on solar geometry that needs to be acquired during architectural education, so that architects participating in the BIM working environments could be prepared for efficient conceptualization of integrated solar systems.

Nakon detaljnog objašnjenja osnovnih elemenata solarne geometrije korišćenjem sferne trigonometrije, u radu je prodiskutovana integracija prikazanih geometrijskih koncepata u BIM okruženja, ilustrovana primerom modula za analize osunčanja u okviru softvera Revit, firme Autodesk.

AB  - This paper continues a research in which it has been confirmed that the angular size-illusion underpins a contradictory effect related to a seeming size-decrease of focused architectural and urban objects as the observer approaches them. It explores the impact of various architectural and urban patterns on the behavior of an angular size-illusion noticeable during movement. To obtain sustainable conclusions, real locations are selected and simplified. Simplification criteria are defined respecting the preconditions necessary to trigger such an illusion. Also, two groups of parameters are formulated, both as illusion quantifiers and illusion qualifiers (such as descriptors and determinants). By analyzing the illusion quantifier's conduct, the established valorization criteria allowed the methodological investigation of influences of illusion determinants on the descriptor's behavior. The outputs-based conclusions are generalized in a form applicable to contemporary architectural and urban practice, making it possible to estimate and control the behavior of the illusion in reality.

AB  - This paper examines the impact of various object-to-camera distances and the number of station-points i.e. various shooting directions with regard to the obtained Density-quality of photogrammetrically created Point-clouds - as digital representations of the existent linear architectural/urban objects/elements. According to an artificial (purified) experimental scene used, the conclusion is that with the chosen focal lengths/object-to-camera distances, with shooting directions perpendicular to the axis of that object, with station-points uniformly radially distributed around it (at a circle of 360deg), and with the obtained values of photogrammetric-software process-quality outputs which belong to the recommended ranges, the achieved density-level of the created Point-clouds may be treated as independent on the camera's radial-movement angle but dependent on the percentage of 'Object's Photo-Coverage': the lower the Coverage, the lower the density. Also, regardless of the Coverage level, the majority of the generated points are generally more 'densimetrically' precise than they are 'densimetrically' accurate.
