Class RawHeightMap

java.lang.Object

com.jme3.terrain.heightmap.AbstractHeightMap

com.jme3.terrain.heightmap.RawHeightMap

All Implemented Interfaces:

HeightMap

public class RawHeightMap
extends AbstractHeightMap

RawHeightMap creates a height map from a RAW image file. The greyscale image denotes height based on the value of the pixel for each point. Where pure black the lowest point and pure white denotes the highest.

Constructor Detail

RawHeightMap

public RawHeightMap(java.lang.String filename,
            int size)
             throws java.lang.Exception

Constructor creates a new RawHeightMap object and loads a RAW image file to use as a height field. The greyscale image denotes the height of the terrain, where dark is low point and bright is high point. The values of the RAW correspond directly with the RAW values or 0 - 255.

Parameters:

filename - the RAW file to use as the heightmap.

size - the size of the RAW (must be square).

Throws:

JmeException - if the filename is null or not RAW, and if the size is 0 or less.

Method Detail

load

public boolean load()

load fills the height data array with the appropriate data from the set RAW image. If the RAW image has not been set a JmeException will be thrown.

Returns:

true if the load is successfull, false otherwise.

setFilename

public void setFilename(java.lang.String filename)
                 throws java.lang.Exception

setFilename sets the file to use for the RAW data. A call to load is required to put the changes into effect.

Parameters:

filename - the new file to use for the height data.

Throws:

JmeException - if the file is null or not RAW.

java.lang.Exception

setHeightStream

public void setHeightStream(java.io.InputStream stream)
                     throws java.lang.Exception

setHeightStream sets the stream to use for the RAW data. A call to load is required to put the changes into effect.

Parameters:

stream - the new stream to use for the height data.

Throws:

JmeException - if the stream is null or not RAW.
