Interface CellularTerrainElevation

All Superinterfaces:

TerrainElevation

All Known Implementing Classes:

AbstractCellularTerrainElevation, EmptyTerrainElevationGrid, FlatTerrainElevation, WaveTerrainElevation

public interface CellularTerrainElevation
extends TerrainElevation

Terrain elevation data that consists of points arranged in a grid structure (2d array). The grid

• needs to be complete (points might have unknown elevation, though)
• does not need to have rectangular grid cells, they may be deformed

Method Summary

PolygonXYZ	getBoundaryPolygon() returns the boundary created from the first and last rows and columns of the grid.
PolygonXZ	getBoundaryPolygonXZ() returns the boundary created from the first and last rows and columns of the grid.
Iterable<? extends TerrainElevationCell>	getCells() returns Iterable over cells.
TerrainPoint[][]	getTerrainPointGrid()

Methods inherited from interface TerrainElevation

getTerrainPoints

Method Detail

getTerrainPointGrid

TerrainPoint[][] getTerrainPointGrid()

Returns:

regular two-dimensional array (not jagged)

getBoundaryPolygon

PolygonXYZ getBoundaryPolygon()

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.

getBoundaryPolygonXZ

PolygonXZ getBoundaryPolygonXZ()

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

getCells

Iterable<? extends TerrainElevationCell> getCells()

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.
