ABSTRACT: The Live Virtual Constructive Architecture Roadmap (LVCAR) report recommended
actions to promote the sharing of tools, data, and information across the Enterprise; and to foster
common formats and policy goals to promote interoperability and the use of common M&S
capabilities. One of the recommended actions was to examine different data storage formats used
across the various architectures to determine the feasibility of creating a set of architecture
independent common data storage formats (CDSFs). One of the categories identified requiring a
common data storage format was 3D manmade features. The CDSF team performed a preliminary
assessment of the ability of nine existing formats to meet 13 requirements for a manmade features
format as expressed in the literature on the topic. The preliminary assessment clearly indicated that
Extensible 3D Graphics (X3D) meets the requirements better than every other format except in one
single case. A deeper analysis of the specific implementation of X3D was performed based upon
this preliminary assessment. The results of this analysis including the specific language of the
requirements are presented this paper and a recommendation is made for adopting X3D as the
CDSF for 3D manmade features.
