An Interactive Modeling System of Japanese Castles with Decorative Objects

We present an interactive modeling system for Japanese castles. We develop an user interface that can generate the fundamental structure of the castle tower consisting of stone walls, turrets, and roofs. By clicking on the screen with a mouse, relevant parameters for the fundamental structure are automatically calculated to generate 3D models of Japanese-style castles. We use characteristic curves that often appear in ancient Japanese architecture for the realistic modeling of the castles.
