Member Function Documentation

osg::Group * Terrain::drawNormals (  osg::Group *  normalGroup = 0  )

Draw the terrain normals. Parameters: normalGroup  The osg group that will contain the normals representation as lines. Null by default, in which case a new group is created to contain all the normals. Returns: The osg group that contains the normals representation as lines

osg::Vec3d Terrain::getFloorNormal (  const double  x, const double  y )  [virtual]

Returns the normal of the floor at the given (x,y) world coordinate. If outside, propagate the border value Implements TerrainInterface.

double Terrain::getFloorZ (  const double  x, const double  y )  [virtual]

Returns the Z coordinate of the floor at the given (x,y) world coordinate. If outside, propagate the border value Implements TerrainInterface.
