SUMMARY
Product two-dimensional design expression has the
superiority of saving time, and can be produced without
complicated modeling and rendreing. Product threedimensional
design expression can present product in defferent
perspectives and obtain more distinct product effects. In
applications two-dimensional and three-dimensional expression
are often used simultaneously to obtain different merits
respectively. Virtual scene interactive technology let people
can interact with designed product and is the development
direction of product design expression in the future.
