III. COMPUTER GRAPHIC TECHNOLOGY IN PRODUCT
DESIGN EXPRESSION
Computer graphic technology can satisfy all the principles
introduced in section II. Generally speaking, product design
expression methods usually include two-dimensional design
expression, three-dimensional design expression and virtual
scene interactive technology.
A. Two-dimentional design expression
Tow-dimentional design expression uses plane effect
picture drawn in computer plane graphic software to present
the shape, proportion, color, texture, lighting and shadow of the
designed product. Tow-dimentional design expression has the
merits of saving time, wonderful effect and free color
adjustment. It has been broadly used in concept design and
scheme design stage of product design [4].
