摘要：Demand for complicated objects in digital contents has been rising as the quality of 3D computer graphics improved.Decorative modeling is useful for enhancing the appearance of objects, however, it is also a difficult task that requiresknowledge of decorative patterns. We propose a support method for 3D geometric modeling of ancient Greek and Romanstyle decor for use in digital contents. Our approach is based on modeling by parts synthesis. These decor styles arecharacterized by organic shapes of foliage and scrolls; thus, we classified 3,313 parts obtained from 200 pictures of foliagedecorations mainly contains acanthus plant according to their shapes and positions. We then extracted 34 representative partsrequired for decorative design and constructed a 3D model library of these parts. The users can design their original decorby assembling them with existing geometric modeling tools. We found the parts can be divided broadly into two categories:fundamental parts that have curves characterize the scroll pattern and the decoration parts that decorates the curves. Efficientgeometric modeling of the European style decor can be achieved by arranging fundamental parts first then decoration parts.Experimental results demonstrate that the user can significantly reduce modeling time decor using our 3D model library.
