Highly interactive 3D geometric modeling J. Liang, M. Green Department of Computing Science, University of Alberta, Edmonton, Alberta, Canada, T6G 2H1 ABSTRACT This paper presents an effort to build a 3D modeling system that can be used for 3D quick prototyping. We focus on providing a highly interactive user interface for 3D direct manipulation, and allowing for the efficient creation and modification of 3D shapes. The main features of the system are (1) the use of kinetic depth effect to provide effective 3D visualization on a traditional CRT screen, (2) the use of a hand-held six degrees of freedom input device (a bat) for direct manipulation of 3D objects, and (3) a set of modeling operations based on the new input device. The system allows a designer to quickly create, modify, place, orient, and organize 3D objects in a natural and intuitive manner. Preliminary results show that such a highly interactive interface has the potential of increasing the efficiency o
