isRepeat

public boolean isRepeat()

doGetHeight

protected double doGetHeight(int x,
                             int y)

Overrides:

doGetHeight in class DelegatingHeightMap

doGetHeight

protected double doGetHeight(float x,
                             float y)

Overrides:

doGetHeight in class DelegatingHeightMap

getExtent

public java.awt.Rectangle getExtent()

Description copied from interface: HeightMap

Get the extent of the height map, if any. The extent is the area it covers and for which it can return meaningful values. A height map may be unbounded in which case this should return null.

Specified by:

getExtent in interface HeightMap

Overrides:

getExtent in class AbstractHeightMap

Returns:

The extent of the height map, or null if it is unbounded.

getIcon

public javax.swing.Icon getIcon()

Description copied from interface: HeightMap

Get a 16x16 icon representing this height map.

Returns:

A 16x16 icon representing this height map.

getRange

public double[] getRange()

Description copied from interface: HeightMap

Get the range of this height map, i.e. the lowest and highest values it can return, as a double array of size two, with the lower bound in index 0 (which must be equal to HeightMap.getBaseHeight()) and the upper bound in index 1.

Returns:

The range of this height map.
