Class AbstractStaticTerrainData

java.lang.Object

org.j3d.terrain.AbstractTerrainData

org.j3d.terrain.AbstractStaticTerrainData

All Implemented Interfaces:

HeightDataSource, StaticTerrainData, TerrainData

public abstract class AbstractStaticTerrainData
extends AbstractTerrainData
implements StaticTerrainData

An abstract representation of the base functionality for a TerrainData implementation.

This class provides a lot of the common functionality that all implementations will require. Good to save you typing.

gridWidth

protected int gridWidth

The width of the terrain in grid points. (Y coordinate)

gridDepth

protected int gridDepth

The depth of the terrain in grid points. (X coordinate)

Constructor Detail

AbstractStaticTerrainData

protected AbstractStaticTerrainData()

Create a new instance.of this data class with all flags set to false.

Method Detail

getTexture

public BufferedImage getTexture()

Fetch the BufferedImage that is used to cover the entire terrain. If no texture is used, then return null. Assumes a single large texture for the entire terrain.

Specified by:

getTexture in interface StaticTerrainData

Returns:

The texture instance to use or null

getGridWidth

public int getGridWidth()

Get the width (number of points on the Y axis) of the grid.

Specified by:

getGridWidth in interface StaticTerrainData

Returns:

The number of points in the width if the grid

getGridDepth

public int getGridDepth()

Get the depth (number of points on the X axis) of the grid.

Specified by:

getGridDepth in interface StaticTerrainData

Returns:

The number of points in the depth of the grid

setTexture

public void setTexture(BufferedImage tex)

Set the texture object that can be used with this terrain instance. Passing a value of null will remove the currently set texture.

Parameters:

tex - The texture instance to use or null to clear
