AB  - In this study, we present and analyse the case of the Workshop titled “A Geometric Adven ture in the World of Grasshopper”, realised in September 2023, at the University of Belgrade,
Faculty of Architecture, within the manifestation called “The Week with Architecture”. The
content of the Workshop has been derived from the elective course “Parametric Modelling”,
offered to the first year master students.
After briefly explaining the teaching context in which the Workshop occurred, we present
the content structure divided into four working days, three of which dedicated to introducing
various programming techniques in the Rhino software and its well-known plug-in Grasshop per, and the fourth day left for the Workshop exhibition completing. Aimed at introducing
programming beginners into basic techniques of algorithmic creation of architectural form,
this Workshop started with an in-house developed Grasshopper definition producing various
2D geometric patterns. Based on this simple definition the students learned the fundamental
elements of the visual algorithmic systems. As a result of first day they produced a range of
different geometric patterns based on the p1 symmetry repetition of circles and polygons on a
predefined rectangular grid. The second day of the Workshop was dedicated to the geometry
of spatial curves, and required from the participating students considerably more programming
understanding and an additional research of the field. The third Workshop day was character ized by an integration of the techniques of the first and the second Workshop day. In this final
programming exercise the participants had to use the geometric grid, in terms of distribution
of a chosen spatial curve.
This teaching activity resulted in excellent geometric models created by participating stu dents, exhibited in the form of prints, the last day of the Workshop. All the Workshop commu nication and information exchange was supported and saved in the specially created TEAMS
learning environment. A catalogue of student submissions is in the process of creation. The
Workshop influenced the teaching of the Elective course “Parametric modelling” in terms of
introducing new topics and rearranging selected teaching activities.

AB  - The magic world of mirrors, their application, integration in interiors and exposure in exteriors, intrigues architectural designers and artists for a long time. Inspired with wide recent usages of mirrors in innovative architectural designs practice, as well as in arts, and grounded our understanding on well-known geometric/optic principles of mirroring, the authors conceptualized a Workshop that was offered to students of architecture, forestry and applied arts, as an extracurricular two-weeks activity. After briefly introducing a historical/chronological overview of mirrors application in architectural design practice and applied art, relevant theoretical aspects of mirroring were demonstrated on the Workshop. The participating students were offered two possibilities for integration of mirrors in their design-outcomes: to experiment with analogue models and digital/computing ones. For that reason, a large amount of small glass mirror parts was provided. Also, functional parametric families of digital mirrors (planar, concave and convex) were developed especially for the workshop and offered on-line. Particular foci of this paper are on both: the teaching methodology that was exclusively prepared for the Workshop, and specific usage of experimentation (to trigger unusual ideas and to utilize relevant familiar methods and procedural activities in the new – this context). In the discussion part of this study, a systematized overview of the Workshop results and its analysis from geometric and semantic point of view are given. The results are divided into: first interim critique, second interim critique and final submission. Through a generalization of conclusions, the lessons learned, namely, the level of subject-related geometric knowledge acquired from this unique teaching experience are reviewed, and an analysis of their possible applications in other pedagogic contexts related to geometry-teaching is presented.

AB  - An angular size-illusion refers to a contradictory effect related to a seeming size-decrease of focused objects as the observer approaches them. This paper continues the research in this field, trying to establish fundamental principles of how to: (a) efficiently perform an on-photo restitution of an illusion's behaviour (expressed by illusion descriptors) when it is experienced in architectural/urban spaces during movement under the influence of available triggers (represented by illusion determinants of physical nature), and (b) manage it computationally so as to be sustainable for contemporary professional practice. To explain that conceptually, one simple architectural/urban matrix is chosen and digitally photographed. Images are photogrammetrically processed and determinants-related data obtained. Subsequently, descriptors-related outputs are calculated by applying derived mathematical equations (expressed in function of those determinants-related data). Then, behaviour-charts are created and corresponding illusion-characteristics read-off. Finally, it is illustrated how to manage (intentionally modify) the restituted behaviour by varying values of acquired determinants-related data. Given results allow also to "design a new illusion" (to programme and control it) by simulating in digital VR/AR environments. Thus, any cause of unwanted/unpredictable visual impression degradations of important architectural/urban structures can be prevented or minimized (by planning and performing adequate spatial/physical interventions on existing/reconstructed/newly designed matrices).

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.

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  - 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 perfom 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, stationpoints 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.
