TerraVision II: visualizing massive terrain databases in VRML
M. Reddy, Y.G. Leclerc, Lee A. Iverson, Nat Bletter · IEEE Computer Graphics and Applications · 1999
To disseminate 3D maps and spatial data over the Web, we designed massive terrain data sets accessible through either a VRML browser or the customized TerraVision II browser. Although not required to view the content, TerraVision II lets the user perform specialized browser level optimizations that offer increased efficiency and seamless interaction with the terrain data. We designed our framework to simplify terrain data maintenance and to let users dynamically select particular sets of geo-referenced data. Our implementation uses Java scripting to extend VRML's base functionality and the External Authoring Interface to offer application-specific management of the virtual geographic environment.
