Interface GeoElevationGrid

All Superinterfaces:
X3DGeometryNode, X3DNode
All Known Implementing Classes:
GeoElevationGrid

public interface GeoElevationGrid extends X3DGeometryNode
GeoElevationGrid is a geometry node defining a rectangular height field, with default values for a 1m by 1m square at height 0.

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes. GeoElevationGrid 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 https://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 interface is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI).
