Description
Technical field
The present invention relates to a kind of application systems based on the network platform, and in particular to a kind of 3D suitable for the network platform is tried
Clothing system, belongs to technical field of internet application.
Background technology
With the popularization of development and the E-business applications of network technology, person increasingly selects in the network platform at present
(such as Taobao, day cat, only product meeting, Jingdone district etc.) buys clothes.Consumer is when choosing clothes, shoes, cap or other ornaments, and one
As be picture presentation after being dressed by model according to the seller in the network platform and selected with reference to corresponding size data
It selects and places an order.Online Shopping clothes often tests the upper body effect that can try clothing in person like that because of no image of Buddha solid shop/brick and mortar store purchase clothes body
Fruit, to bought dress ornament usually occur because the color that model's picture is shown has deviation, size data inaccuracy, practical upper body effect
Fruit and the problems such as desired effect differs greatly, the material quality of dress ornament is difficult to ensure.Above problem consumer occur can only pass through
It returns goods and exchanges goods to be remedied, but still time and the fiber crops returned goods with come band of exchanging goods that consumer's webpage is chosen can be wasted
Tired, the interconnection net purchase clothes body for largely effecting on consumer is tested.
