碩士 === 大同工學院 === 資訊工程學系 === 84 === Shape design is an important task in CAD/CAM/CAID. Traditionally, this is achieved by manipulating the control points of the free form surfaces (e.g., NURBS). Such a methodology can be quite tedious and non-intuitive. Besides, the perfection of such technique requires a strong background of geometry and mathematics, which industrial designer often lack. This research proposes a new shape design paradigm. After reviewing many shape design methods in CAD and modeling literature, we propose a new shape design paradigm. This method uses minimum energy principle to control the shape of the object. This enables the designer to use intuitive tools to modify the shape of the objects. B-spline is widely used in CAD and animation. One focus of this research is that we intended to work on the B-spline representation . With this, the research can directly benefit the CAD/CAM community (besides CG/ animation/multimedia). This research also intends to combine aspects of force feedback from virtual reality. The designer can not only see the deformed, but also can haptically deform the object, the concept of WYSIWYF (what you see is what you feel). We believe such an integration will be an essential enhancement to the next generation shape design environment.
