Abstract:

We propose a support method for 3D geometric modeling of ancient Greek and Roman style decor for use in digital contents. Our approach is based on modeling by parts synthesis. These decor styles are characterized by organic shapes of foliage and scrolls; thus, we classified 3,313 parts obtained from 200 pictures of foliage decorations mainly contains acanthus plant according to their shapes and positions. We then extracted 34 representative parts required for decorative design and constructed a 3D model library of these parts. The users can design their original decor by 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. Efficient geometric modeling of the European style decor can be achieved by arranging fundamental parts first then decoration parts.
