Three-Dimensional Modeling Interface for Augmented Realities

Today’s geometric modeling tools are usually controlled by the mouse and keyboard. 3dmodeling operations are often constrained to planes or lines to make modeling easier. New augmented reality devices promise new classes of applications with natural 3d user interfaces. This paper deals with a new method that enables users to model 3d shapes directly with their fingers. It is implemented in Artist3D, which is a modeling tool that constraints modeling operations implicitly to planes and lines. The new method can also be integrated into commercial modeling tools.
