SnowHeightMap

public SnowHeightMap(EditSession session,
 Region region,
 @Nullable
 Mask mask)

Constructs the SnowHeightMap.

Parameters:

session - an edit session

region - the region

mask - optional mask for the height map

Method Details

applyFilter

public float[] applyFilter(HeightMapFilter filter,
 int iterations)

Compute the new heightmap with the filter 'iterations' amount times.

Parameters:

filter - the filter

iterations - the number of iterations

Returns:

new generated heightmap of the terrain

applyChanges

public int applyChanges(float[] data,
 int layerBlocks)
                 throws MaxChangedBlocksException

Apply a raw heightmap to a region. Use snow layers.

Parameters:

data - the data

layerBlocks - amount of blocks with type SNOW_BLOCK

Returns:

number of blocks affected

Throws:

MaxChangedBlocksException - if the maximum block change limit is exceeded
