Fabric drape simulations accomplished by computer graphics software can provide the basis for effective communication among designers, manufacturers and other players in the apparel industry. The goal of our study was to investigate various 1D and 2D shape descriptors used to characterize renderings of 3D drape simulations in dependence on the geometry of collision objects and fabric type. Image processing routines were implemented to extract and compute the shape descriptors while principal components analysis was applied to interpret the relationships among the parameters studied. Drapes on cube, octahedron and prism were found to behave in a distinctively different manner compared to those produced using the other six collision objects: cone, cylinder, dodecahedron, gengon, sphere, and tube. A first principal component can be, to a large extent, represented by the following mutually strongly correlated 2D shape descriptors: area, major axis length, minor axis length, equivalent diameter, and perimeter. Analysis using 1D shape descriptors confirms these findings and additionally suggests that rubber-based drapes contain the lowest number of folds while those on polyester, wool, and sometimes silk and/or satin are characterized by the highest number of drape folds. These results were confirmed by visual examination of the drapes simulated.

Symulacja układalności tkanin realizowana przy pomocy programu grafiki komputerowej może być podstawą dla efektywnego porozumienia pomiędzy projektantami i wytwórcami w przemyśle odzieżowym. Celem naszych badań było rozpoznanie różnych deskryptorów kształtu 1D i 2 D dla scharakteryzowania renderów 3D symulacji układalności w zależności od geometrii obiektów kolizji i typu płaskich materiałów. Zastosowano metody obróbki obrazu dla wybrania i obliczenia deskryptorów kształtu w celu ustalenia zależności pomiędzy podstawowymi badanymi parametrami. Stwierdzono, że układalności na sześcianie, ośmiościanie i graniastosłupie zachowują się w sposób odrębny od pozostałych sześciu obiektów kolizji. Stwierdzono, że w dużej mierze następujące deskryptory kształtu są silnie wzajemnie skorelowane: powierzchnia, długość podstawowej osi, długość mniejszej osi, zastępcza średnica i zastępczy obwód. Analiza z zastosowaniem deskryptorów kształtu 1D potwierdza te ustalenia i dodatkowo pozwala na sugestię, że kształty wynikające z pokrywy gumowej zawierają najmniejszą ilość fałd, podczas gdy te z tkanin poliestrowych i wełnianych, a czasami i jedwabnych charakteryzują się przez najwyższa ilość fałd. Uzyskano dobrą korelację kształtów symulowanych i uzyskanych z pomiarów.
