“…A promising option for solving the specified problems is the use of graphical systems that are focused on a complex shape [10,11]. All leading global companies in the field of development of software garments for the fashion industry contain the modules of visualization of a three-dimensional figure due to a digital image or body-scanning data [12,13]. Mathematical modeling and the construction of a linear frame is performed with the help of embedded software functions and operators.…”

“…National anthropometric standards of Great Britain, United States, and Mexico are created based on databases obtained by body scanning, which proves the feasibility of this technology for upgrading anthropometric information [8,13,15]. However, the use of a body scanner is costly, and thus inaccessible to most users.…”

Технологія побудови геометричної моделі об'єкта представлена трьома видами інформаційних моделей: цифрова, сітчаста, поверхнева. В результаті аналітичних та експериментальних досліджень обґрунтовано алгоритм проектних ситуацій здійснення перетворень поверхні вихідного об'єкту, яким виступає електрон ний манекен, в конструкцію виробу. Теоретично обґрунтовано вихідну базу даних для побудови та модифікації каркасних 3D-моделей манекенів, з метою забезпечення достовірності їх візуалізації. Досліджено механізм інтерактивного модифікування оболонок поверхні одягу в циклі його силуетної деформації та побудови плоских розгорток одягу адаптованих до векторів модифікування ділянок поверхні манекена, для отримання конструкцій виробів ідентичних оригіналу морфологічної структури тіла споживача. Запропоновано 4 сценарії проектних ситуацій відтворення та трансформації 3D-моделі силуетної поверхні манекена та виробу за оптимальним маршрутом, для підвищення швидкості та якості процесів комп'ютерного конструювання деталей одягу на фігури типової та нетипової тілобудови. Апарат побудови зображень цифрової моделі тривимірного об'єкта враховує топологію геометричної структури форми та морфологічне поле синергетичних зв'язків елементів в процесах переходу від 3D до 2D проектування. Сценарій адаптації силуетних 3D зображень виробу до модифікованих 2D конструкторських документів на засадах верифікації бази даних. Оцінку ефективності технології конструювання швейних виробів виконано за кількістю ітерацій проектних операцій в проектних процедурах з перевіркою рівня якості Ключові слова: математична модель, 3D манекен, 2D розгортка одягу, деформація поверхні, силуетна трансформація, моделюючий ефект, універсальна конструкція

“…The virtual human body mannequin based on 3D anthropometry can be created by two methods: 1) the manual avatar, using body measurement; 2) the direct avatar, using 3D body scan form [8]. 3D body scanning is a relatively new method [12]. By the advanced 3D scanning techniques, the individual human body can be easily captured [13].…”

Nowadays, virtual try-on is an irreplaceable technology in fashion industry, so it is very important to prove virtual try-on matching with the real garments. Therefore, the aim of this research was to compare garment fit using virtual try-on and scanning technologies. For this reason, garment visual appearance and distance ease between straight fit dress and mannequin in respect to fabrics properties were investigated. Women mannequins in different sizes were scanned by 3D scanner VITUS Smart XXL without and with the real straight fit dresses made from five different woven fabrics. Fabrics mechanical properties were defined by KES-F. Scanned mannequins were covered with the same size and fabric virtual dresses by Modaris 3D (CAD Lectra). Distance ease of virtual and scanned garments was compared in bust and waist cross-sections. It was defined that distance ease values at bust girth of real and virtual dresses differed till 29.9 % (1.16 cm), while at waist varied from 7.3 % (0.51 cm) to 47.3 % (4.30 cm) because of wrinkles in this area. Generally, appearance of the virtual dresses was similar to real dresses with some differences in garment shape fluency, however by increasing of the mannequin size, similarities decreased. It was assumed that very high shear rigidity G could not be very well reflected in 3D CAD system, therefore differences between virtual and real dresses appearance occurred. The general appearance and form of bust and waist cross-sections of virtual dresses with fabric 03 had less similarities comparing with real dresses due to high G value. So, comparative study showed that the accuracy of virtual try-on was quite useful comparing to real garments, if shear rigidity of fabrics was lower than 1.6 N/m*º and tensile strain in warp direction was higher than 1.80 %.

“…Virtual cloth and clothing simulation received significant attention in the past decade. Today, advanced computer simulation techniques and garments virtual prototyping are indispensable for the development of garments and their fitting on the 3D body models within a virtual environment, as well as real-time virtual clothes try-on [10][11][12][13]. It was discovered that virtual prototyping and garments fitting represent a problem for the standard [14,15] and non-standard body shapes [16][17].…”

Proiectarea îmbrăcămintei funcționale pentru persoanele cu dizabilități fizice sau cifoză prin utilizarea tehnicilor de simulare pe calculator Obiectivul dublu al acestui studiu este de a documenta provocările actuale ale tehnicilor de scanare 3D și de simulare pe calculator pentru dezvoltarea de articole de îmbrăcăminte funcționale pentru persoanele cu dizabilități fizice sau cifoză posturală. Prima parte a studiului investighează problemele de sănătate ale utilizatorilor de scaune cu rotile și prezintă posibilitățile de dezvoltare a pantalonilor funcționali din perspectiva nevoilor de protecție și de sănătate. Cea de-a doua parte a studiului investighează utilitatea metodologiei nou dezvoltate pentru evaluarea suprafețelor elementare, numită CASP (Curvature, Acceleration, Symmetry, Proportionality), în procesul de proiectare a corsetului bine montat pentru utilizatorii de scaune cu rotile care suferă de afecțiunea cifoză posturală. Relațiile dintre problemele de sănătate, pozițiile corpului uman, cifoza, scanarea 3D, evaluarea CASP și articolele de îmbrăcăminte tratate au fost luate în considerare în procesul de prototipare. Rezultatele obținute în ceea ce privește pantalonii funcționali pentru utilizatorii de scaune cu rotile și corsetul bine montat pentru un corp cu cifoză sunt valoroase și pentru o populație mai largă a celor care sunt forțați să stea în picioare în timpul zilei și care se confruntă cu probleme de sănătate similare, cum ar fi persoanele care suferă de paraplegie sau cele care sunt afectate de cifoză. Cuvinte-cheie: îmbrăcăminte funcțională, dizabilitate fizică, afecțiuni posturale, scanare 3D, metodologie CASP, tehnici de simulare pe calculator Designing the functional garments for people with physical disabilities or kyphosis by using computer simulation techniquesThe two-fold purpose of this study is to document the current challenges of the 3D scanning and computer simulation techniques in developing functional garments for people with physical disabilities or postural disorder kyphosis. The first part of the study investigates the health problems of the wheelchair users and presents the possibilities of developing functional pants from the perspective of protection and health needs. The second part of the study investigates the usefulness of the newly developed methodology for elementary surfaces evaluation, named CASP (Curvature, Acceleration, Symmetry, Proportionality), in the process of designing the well-fitted bodice for wheelchair users suffering from the postural disorder kyphosis. The relationships between the health problems, human body postures, kyphosis, 3D scanning, CASP evaluation and treated garments were considered in the prototyping process. The obtained research results regarding the functional pants for wheelchair users and the well-fitted bodice for a kyphosis body are valuable also for a wider population of those who are forced to a sitting posture during a day and are confronted with similar health problems as paraplegics or are affected by the kyphosis.
