摘要：

Most of existing 3D-CAD and SD-CG softwares have problems in intuitive manipulation and representation of 3D curved surfaces. This paper discusses design issues and a prototype system of an immersive modeler which enables a user to design intuitively and interactively 3D solid objects with curved surfaces by one's hand and finger. Shape deformation is expressed by simple formulas without complex calculation because of skeletal implicit surfaces employed to represent smooth free-form surfaces. A polygonization algorithm that generates polygonal representation from implicit surfaces is developed to reduce the time required for rendering curved surfaces, since conventional graphics hardware is optimized for displaying polygons. The prototype system has shown that a user can design 3D solid objects composed of curved surfaces in a short time by deforming objects intuitively by one's hand and finger in real-time.
