Constructor Detail

AbstractCellularTerrainElevation

public AbstractCellularTerrainElevation(AxisAlignedBoundingBoxXZ boundary,
                                        int numPointsX,
                                        int numPointsZ)

Method Detail

getTerrainPoints

public Collection<TerrainPoint> getTerrainPoints()

Specified by:

getTerrainPoints in interface TerrainElevation

getTerrainPointGrid

public TerrainPoint[][] getTerrainPointGrid()

Specified by:

getTerrainPointGrid in interface CellularTerrainElevation

Returns:

regular two-dimensional array (not jagged)

getBoundaryPolygon

public PolygonXYZ getBoundaryPolygon()

Description copied from interface: CellularTerrainElevation

returns the boundary created from the first and last rows and columns of the grid. This requires that all TerrainPoints' elevations have already been set to non-null values.

Specified by:

getBoundaryPolygon in interface CellularTerrainElevation

getBoundaryPolygonXZ

public PolygonXZ getBoundaryPolygonXZ()

Description copied from interface: CellularTerrainElevation

returns the boundary created from the first and last rows and columns of the grid.

Specified by:

getBoundaryPolygonXZ in interface CellularTerrainElevation

getCells

public Iterable<? extends TerrainElevationCell> getCells()

Description copied from interface: CellularTerrainElevation

returns Iterable over cells. This is a convenience method for operations that need to be performed for all cells. The iterator cannot be used to remove cells.

Specified by:

getCells in interface CellularTerrainElevation

getElevation

protected abstract Float getElevation(VectorXZ pos)
