To create a scene in a virtual world as close as
possible to a real world counterpart requires a lot of manual
steps and subsequently time. In order to reduce the steps and
time above, geo databases with the spatial extension combining
with a customized data management application shown here can
be used. Combining this application with other applications such
as image comparison applications, can help achieve the
automation of the process of placing model such as military
buildings into a scene. This application was developed as web
application using geo spatial open source software and tools such
as Openlayer and Geoserver. It operates on vector data stored in
PostGIS database. Scene developers can use the application to
search for different GIS-layers’ data of an area. Search
arguments can be a key word or coordinates, which need the
spatial processing ability of the PostGIS DBMS to find results.
The search results are mapped with the matched models. This
helps reducing the scene developing time. In this paper, the focus
is on how the aforementioned application and database design
help ease the process of automated placing matched 3D models
into scenes based on vector data of GIS Layers in the database
and how this application is developed. With continual
improvement of GIS open source software, a spatial database
management program can be easily built. Moreover, the use of
these open source software can reduce the cost of virtual world
products. DTI as a research organization can and will benefit
from this. |
