The process described here is needed
in order to obtain a full VRML hierarchical description of the database
space.
VRML (Virtual Reality Modeling Language)
is featured to describe tri-dimensional spaces and environments with objects
inside them.
VRML files are ascii files that
can be interpreted by VRML browsers. A VRML browser enables the navigation
of the spaces described by VRML files. Our objects are really very simple
geometrical shapes because they must represent the clusters.
Fig 1 shows how the data contained
in cluster tables are used to build VRML files.
Fig 2 shows the process that creates
a hierarchical structure of VRML files starting from cluster tables.
