Proposed enhancements to the X3D geospatial component

Abstract

The Geospatial Component of the X3D Standard suffers from some deficiencies that prevent its wider adoption. This paper addresses two of these deficiencies. The first problem is that in order to reduce spatial jitter content must be built with regionally defined GeoOrigin nodes. This approach is fine for localized regional geospatial data visualization requirements, but fails for accurately viewing data in a global context or for combining content with different GeoOrigins. The second problem is the limited options for providing terrain data to the browser for rendering. The GeoLOD node is not the optimal solution for allowing the X3D browser to render terrain data in a high performing manner. This paper presents solutions to these problems for consideration by the Web3D community.
