| This paper presents a virtual reality interface tool which allows a user to perform the
following action : 1.Import design from other CAD tools. 2.Assemble an architecture structure from a library of pre-built blocks and
geometry primitives dynamically created by user. 3.Export the design interactively in VRML format back to the library for Internet
browsing. The geometry primitives include polygon, sphere, cone, cylinder and cube. The
pre-built blocks consist of fundamental architecture models which have been
categorized with architectural related style, physical properties and environmental
attributes. Upon a user’s request, the tool or the composer, has the ability to
communicate with the library which indeed is a back-end distributed client-server
database engine. The user may specify any combination of properties and
attributes in the composer which will instantly bring up all matching 3-dimensional
objects through the database engine. The database is designed in relational model
and comes from the work of another research group. |
