Abstract

We describe some of our recent work on the computer-assisted acquisition, interaction, manipulation and display of three-dimensional data in general, and the human body form in particular. The work encompasses four distinct areas: 1) the automatic acquisition of 3-D surface points using a light-scanning technique, 2) the automatic construction of mathematical surface descriptions from point-contour data, 3) interaction and manipulation of 3-D data with multiple hand-mounted sensors, and 4) real-time stereo display of computer-synthetized continuous-tone images on special head-mounted display devices. We present some of our preliminary results in each of these areas and outline how they will be combined into a single comprehensive system. This system we expect will significantly enhance the computer's capabilities to assist in working with complex three-dimensional structures such as human bodies. As a simple example, we expect the system should be able to automatically digitize a human model, and within a few minutes generate a three-space approximating surface conforming to the human model's surface. Another person, wearing a helmet-like display device, will see through his helmet's visor not only the human model, but also the computer-generated approximating surface superimposed on it. As this human viewer moves around the model, the computer-generated surface will appear to stay on the model, and he'll be able to reach out and modify any portion of it or indicate that the digitizing system should rescan parts of the sur-face whose approximation he deems unsatisfactory. Other applications of the system for diagnostic medicine, architecture, and molecular modeling will also be suggested.
