  • Publication number: 20080036762
    Abstract: The present invention relates to a system and method, which establish a plug-in relationship with a graphic program, such as Adobe Illustrator, and are adapted to reconstruct each face in three dimensions to include content designed in a two-dimensional development figure, thus converting a two-dimensional object into a three-dimensional object. In the three-dimensional design method, shapes of basic boxes are presented to a user. Dimensions corresponding to a box shape selected by the user are received. Coordinate values of a development figure are changed depending on the dimensions received from the user. A development figure suitable for the changed coordinate values is presented to the user. The design made by the user is partitioned to correspond to faces of the development figure. Three-dimensional coordinate values are set based on input coordinate values. The partitioned design is arranged on the three-dimensional coordinate values, thus generating three-dimensional data.
