Applied 3D Virtual Try-on for Bodies with Atypical Characteristics

AbstractThe manufacture of clothing using real body measurements is based on user's new profile, on their own desire for individualization through purchased garments but also on the results of the anthropometric surveys which have shown great variability in morphological types, especially for women.Research conducted by the authors focused on the application of 3D virtual try-on in pattern alterations for “women trousers”. To achieve the objectives of the work, bodies with atypical characteristics were selected from the database resulting from 3D scanning of the Romanian women population. In the study, it was found that many women have different sizes for the two hip contours (left-right), differences being in the range 1.5 to 4.5cm.Based on these considerations a method of completion of the patterns for trousers has been developed and applied, by 3D simulation of the body-garment.This paper brings contributions to clothing design technology by 3D virtual try-on, taking into account the body shape of the users

INNOVATIVE CLOTHING DESIGN FOR WOMEN DURING PREGNANCY

During pregnancy there is an evident change in the physical appearance of a woman's body. The most evident change is the substantial weight gain, increased abdominal region, torso and hip, and limbs thickening. Physical changes leads to the need of a wardrobe changing, especially in the fourth month of pregnancy. Given these factors the question arises is to identify the transformations of body conformation and ensure a maximum comfort in developing clothing products for this category. Because it is a continuous transformation, the products must be designed to be adjustable and versatile, ensuring their usability for a long period of the pregnancy and even after birth. The paper presents the specific algorithms for body conformations during pregnancy and the patterns designed based on these algorithms with the proper modifications. The principle of designing clothes for pregnant women refers to the introduction of pregnancy-related size changes in the standard method of pattern design. The research was conducted by INCDTP during the initial stage of a project, financed through national founds, consisting in a documentary study on morphologic indicators of women during the pregnancy period, the changes observe and their application in pattern design. Following the principles specific to the product group studied regarding comfort and style, INCDTP specialists have developed and produced a collection of clothing products for women during pregnancy. Key words: Pregnancy, algorithms, proportions, morphological indices, pattern design, clothing, change

ROMANIAN FOLKLORE MOTIFS IN FASHION DESIGN

The traditional Romanian costume such as the entire popular art (architecture, woodcarvins, pottery etc.) was born and lasted in our country since ancient times. Closely related to human existence, the traditional costume reflected over the years as reflected nowadays, the mentality and artistic conception of the people. Today the traditional Romanian costume became an inspiration source to the wholesale fashion production industry designers, both Romanian and international. Although the contemporary designers are working in accordance with a vision, using a wide area of styles, methods and current technology, they usually return to traditional techniques and ethnic folklore motifs, which converts and resize them, integrating them in their contemporary space. Adrian Oianu is a very appreciated Romanian designer who launched two collections inspired by his native’s country traditional costumes: “Suflecata pan’ la brau” (“Turned up ‘til the belt”) and “Bucurie” (“Joy”). Dorin Negrau had as inspiration for his “Lost” collection the traditional costume from the Bihor region. Yves Saint Laurent had a collection inspired by the Romanian traditional flax blouses called “La blouse roumaine”. The paper presents the traditional Romanian values throw fashion collections. The research activity will create innovative concepts to support the garment industry in order to develop their own brand and to bring the design activities in Romania at an international level. The research was conducted during the initial stage of a project, financed through national founds, consisting in a documentary study on ethnographic characteristics of the popular costume from different regions of the country

A STUDY ON USING 3D VISUALIZATION AND SIMULATION PROGRAM (OPTITEX 3D) ON LEATHER APPAREL

Leather is a luxury garment. Design, material, labor, fitting and time costs are very effective on the production cost of the consumer leather good. 3D visualization and simulation programs which are getting popular in textile industry can be used for material, labor and time saving in leather apparel. However these programs have a very limited use in leather industry because leather material databases are not sufficient as in textile industry. In this research, firstly material properties of leather and textile fabric were determined by using both textile and leather physical test methods, and interpreted and introduced in the program. Detailed measures of an experimental human body were measured from a 3D body scanner. An avatar was designed according to these measurements. Then a prototype dress was made by using Computer Aided Design-CAD program for designing the patterns. After the pattern making, OptiTex 3D visualization and simulation program was used to visualize and simulate the dresses. Additionally the leather and cotton fabric dresses were sewn in real life. Then the visual and real life dresses were compared and discussed. 3D virtual prototyping seems a promising potential in future manufacturing technologies by evaluating the fitting of garments in a simple and quick way, filling the gap between 3D pattern design and manufacturing, providing virtual demonstrations to customers
