From VRML 2 Basic Concepts and Definitions CPS616 -- Information Track of CPS -- Spring Semester 98. by Zeynep Ozdemir, Rob Baker, Meryem Ispirli, Geoffrey C. Fox

VRML2.0 Example of ElevationGrid
ElevationGrid { set_height # eventIn MFFloat color NULL # exposedField SFNode normal NULL # exposedField SFNode texCoord NULL # exposedField SFNode height [] # field MFFloat ccw TRUE # field SFBool colorPerVertex TRUE # field SFBool creaseAngle 0 # field SFFloat normalPerVertex TRUE # field SFBool solid TRUE # field SFBool xDimension 0 # field SFInt32 xSpacing 0.0 # field SFFloat zDimension 0 # field SFInt32 zSpacing 0.0 # field SFFloat }
Defines a two dimensional array in x-z plane with height given in height
texCoord is critical to drape interesting land structure over this framework
