Virtual Reality Sculpture Using Free-Form Surface Deformation
Todd J. Furlong · 1997
Abstract Free-form deformation allows a user to deform surfaces in an intuitive manner that has been compared to sculpting clay (Sederberg and Parry, 1986). This research investigates the use of this deformation technique to create virtual sculpture in the Iowa State University C2, a CAVE™-like apparatus. Emphasis is on intuitive and direct interaction with a surface in order to mold it into whatever shape the user has in mind. An icon-based menu is provided for changing modes of interaction, and a 3D paint tool allows users to add color to their models. Possible applications of this research include virtual art and conceptual or industrial design.
