A SOLID MODELING LIBRARY FOR THE WORLD-WIDE-WEB

A library of functions for the creation, manipulation, and viewing of solid models was created for deployment on the World Wide Web. The cor e data structure was based on the halfedge boundary-representation dat a structure proposed by M. Mantyla bur much functionality had been add ed. It provided an alternate, constructive-solid-geometry interface to the core data structure. It was initially implemented in C and subseq uently re-implemented in Java. An interface to the STEP standard and v arious applications such as a simple solid modeling applet, a conic il lustrator applet, and a virtual furniture showroom applet had been bui lt. It is bring extended to support multiple simultaneous users as par t of a prototype WWW-based tele-processing manufacturing system. (C) 1 998 Elsevier Science B.V. All rights reserved.
