3-D Design of Free-Form B-Spline Surfaces

Abstract

This report describes an experimental system for designing free-form B-spline surfaces using a head-mounted display. In this system, the interaction with the surfaces takes place in three dimensions as the designed object's shape is updated in real-time. The report also examines some of the problems that should be solved in building a practical three-dimensional computer-aided geometric design system for surfaces.
