A Web3D based CAESAR viewer

The CAESAR (Civilian American and European Surface Anthropometry Resource) project completed in 2002 has collected 3D scans of over 5000 subjects. We have created a 3D interface, the NIST CAESAR Viewer (NCV), utilizing the Virtual Reality Modeling Language (VRML) to provide 3D access via the Web. In addition to simply viewing the 3D scans we have augmented the display of the body with interactive anthropometric landmarks and contour line displays. The landmarks and viewpoints associated with the landmarks are automatically placed onto the body as a visual anthropometric glossary. Display of the contours boundaries are adjusted by the user moving sagittal, coronal and transverse cutting planes. This paper describes the functionality of the evolving NCV viewer.
