Abstract
When we design 3D objects in virtual environment, we combine and deform various primitives such as line, triangle, polyhedron like a cube and sphere. This method is effective in constructing simple objects. However, it requires enormous effort to construct more complex objects. We propose a new method by using autonomous free-form surface. Users intervene in autonomous deformation process. Cooperative work by two users often leads to more effective work. In this research, we developed a system that enables two users to work simultaneously in virtual environment with force feedback. And we developed autonomous free-form surface which has surface tension. Through experiments in deformation of the surface, the effectiveness of cooperative work in virtual environment is tested.
