public class GeoElevationGridObject
extends X3DConcreteNode
implements GeoElevationGrid
GeoElevationGrid is a geometry node defining a rectangular height field, with default values for a 1m by 1m square at height 0.

X3D node tooltip: [X3DGeometryNode] GeoElevationGrid is a geometry node defining a rectangular height field, with default values for a 1m by 1m square at height 0. Vertices corresponding to GeoElevationGrid height values define quadrilaterals, which are placed above or below a curved geospatial surface using geographic coordinates.
  • Hint: the height array defines (xDimension-1)*(zDimension-1) quadrilaterals.
  • Warning: generated quadrilaterals can be nonplanar. Tessellation splits quadrilaterals into triangles along seam starting at initial vertex of the quadrilateral and proceeding to opposite vertex.
  • Hint: positive direction for normal of each triangle is on same side of the quadrilateral. Triangles are defined either counterclockwise or clockwise depending on value of ccw field.
  • Hint: GeoElevationGrid can contain GeoOrigin, Color|ColorRGBA, Normal and TextureCoordinate nodes.
  • Hint: insert a Shape node before adding geometry or Appearance.
  • Hint: X3D for Advanced Modeling (X3D4AM) slideset http://x3dgraphics.com/slidesets/X3dForAdvancedModeling/GeospatialComponentX3dEarth.pdf
  • Warning: requires X3D profile='Full' or else include <component name='Geospatial' level='1'/>
  • Warning: avoid having GeoLocation or GeoTransform as a parent or ancestor node of GeoElevationGrid, since multiple geospatial transformations then occur with unpredictable results.

Package hint: This org.web3d.x3d.jsail concrete class is used for implementing a standalone X3D object as a Plain Old Java Object (POJO). If you are writing Java code for use inside an X3D Script node, compile separate code using only the org.web3d.x3d.sai package instead.
