In fact, the key to the quality of the fitting mirror is its embedded software. If the fitting software technology is good, the rendering effect of the fitting mirror will be good.
At present, most fitting mirrors adopt patch technology, which rigidly sticks the human body and clothes together, rather than the clothes actually worn by the human body. This is the reason why fitting mirrors and online fitting software are not popular for a long time.
You can have a look at "Test Installation", which is the software with the highest technical level in China. It has changed from a US military project to a civilian project, allowing users to try on clothes of different styles and sizes with their own bodies, visually seeing the fit between clothes and bodies, and there are many interactive small functions such as dragging clothes with the mouse.
