TopIntroduction
In recent years, with the continuous development of computer software level, the continuous improvement of hardware performance and the continuous popularity of 3D scanning equipment, the threshold of 3D data acquisition has been greatly reduced. Nowadays, 3D data has become another important digital media following sound, image and video. 3D human body and virtual clothing, as two common 3D models, have always been an important research content in computer graphics and machine vision, and have been widely used in film and television, games, clothing design, virtual fitting, e-commerce and many other areas of people's livelihood.
The virtual clothing is one of the research hotspots in the virtual reality and computer graphics field. As the foreign clothing e-commerce has developed very early, most clothing websites have already can provide the 3D view, purchase history record, virtual fitting room, auxiliary facilities and other services. For example, the famous fitting website – My Virtual Model provided the online fitting service of human body measurement; the scientists from the Germany Fraunhofer Gesellschaft and other scientific research team jointly develop a set of fitting system. Virtual clothing, is a digital fashion using computer technology to simulate the fabric. The comprehensive consideration of clothing sample version, fabric characteristics, body and human movements, and clothing shape and its changes, are all obtained through computer simulation.
Virtual clothing display is the use of holographic technology, the Internet or digital interactive large screen to show the dynamic visual effects when the human body or the digital model-”dressing” virtual clothing. With the development of digital media art, interactive and three-dimensional display technology, virtual clothing display system is widely used in 3-D fashion design, fashion shows, entertainment, “virtual dressing system” in shopping malls and television advertising area. This paper analyzes and compares several technologies in recent years, summarizing a human computer interaction model. It is concluded that, with the development of smart environment technologies such as holographic, somatosensory interactive, three-dimensional vision and augmented reality, a personalized, stylish and intelligent virtual fitting experience as the representative of “private order” will be an important part.
When debugging large applications, computers have a low configuration. Visual C++ provides remote debugging capability to facilitate program developers to debug programs stored on highly configured machines.
In the garment industry, the application of three-dimensional human body/garment modeling and simulation is booming, and personalized customization is gradually becoming the norm. The continuous improvement of the accuracy of 3D human body reconstruction will certainly bring new opportunities for the personalized advanced customization industry. Traditional clothing design requires designers to have a variety of professional skills such as plate making, code placing, sewing, etc. Most importantly, in the design process, it is impossible to directly see the fitting effect of clothing, but can only operate the two-dimensional cut pieces. In contrast, mature 3D clothing simulation software such as Optitex3D in the US, Lecra in France, AGMS Industry3D in Japan, Clo3D and Marvelous Designer in Korea, and 3D modeling software such as Maya, Blender et al. can directly sew a 2D garment cut piece into a 3D garment and wear it on a 3D human body. By using the physical simulation technology of fabric, the drape, fold and other real effects of the garment on the human body can be generated.
Comparing to the foreign fitting system, the relevant domestic research also can get a certain progress. The recent representative researches include: Literature (Li Y, Zhang W, Fan J.(2014)) introduces the development history and current condition of virtual clothing, and pays attention to introduce the research works of various research institutes; Literature (Luximon A.(2015)) gives the improved realistic simulation equation of material point-spring model and clothing by analyzing the basic steps of clothing virtual simulation, and carry out the solution of dynamic system; Literature (Miao L, Shang S Y, Cai C X.(2013)) researches the 3D clothing simulation technique in the virtual human animation, including the virtual human body modeling, character animation, physical simulation of cloth and collision detection and response of deformable body, of which the overall objective is to construct a complete 3D clothing simulation environment and complete the development of efficient algorithm around the system real-time performance.
