Threedimensional, or 3D technology creates visual illusions (錯覺 ) and enables people to see images in the round that are actually only twodimensional.

With the development of new threedimensional digital technologies, it has been changing people’ s ways of municating and working. Digital cameras that record in 3D have been brought to market. Manufacturers have also launched 3D digital photo frames, which can broadcast 3D photos. Processing software allows flat photos in the frame to achieve 3D visual effects that can be seen by users without wearing special glasses. After nine years of research, China took the lead to establish a 3D Inter marketing platform. Inter users can go shopping in a 3D environment just like in the real world by selecting goods, checking reviews and trying out remended goods.
