4. APPLICATIONS FOR FASHION AND APPAREL INDUSTRY
4.1 Virtual-try-on
The so called virtual-try-on solutions have gained importance in the last few years in different areas of the fashion industry.
Virtual-try-on solutions simulate digitally the behavior of textiles onto the human body. In this way, they allow a virtual probe of cloth items onto digital human body models. 3D cloth simulation engines are employed to determine precisely how the cloth item will behave on the digital body model. Figure 15 shows an example of such solutions from Assyst-Bullmer13. The different parts of textile defining a piece of cloth are described as 2D patterns (as it is the case for usual CAD solutions employed in cloth manufacturing processes). For each part are specified all the required characteristics of textile, such as for example thickness or elasticity. The different parts are then placed in a 3D environment around a digital human body model and stitched together. The 3D cloth simulation engine will then determine the behavior of the so formed cloth item over the human body model.
Virtual-try-on solutions are becoming interesting to different areas of fashion industry. For example, fashion designers can employ such systems to obtain first visual results of their creations without the need of the production of real prototypes. Cloth buyer can see remotely new cloth items without the need to have the real pieces shipped from distant locations. Experts dealing with styling of persons can show their clients how they will look before they buy new dresses. Some web-shopping solutions are also exploiting this technology to present their cloth items in 3D on virtual mannequins.
Various virtual-try-on solutions are available on the market. Modern and sophisticated solutions, as for example from OptiTex14 (Figure 16), allow to import data from 3D scanning systems and simulate different poses of the human body model. Some of them allow additionally to import motion information from previously recorded data. In this case, the behavior of the textile is simulated dynamically.
4.2 Virtual-make-over
Virtual-make-over solutions deal with the virtual styling persons in the area of the face, by changing or adding virtually make-up, haircuts or accessories. Figures 17 and 18 show examples in hairdressing (by Stellure15) and accessoring (by Visionix16). In both examples, the appeal of the human face is changed virtually by adding digitally to a digitized 3D human face, haircuts or glasses.
