TerrainConfig

public TerrainConfig()

Creates new default terrain config

Method Detail

setLodRanges

public void setLodRanges(float[] lodRanges)

Setting this terrains lod stage area ranges.
lodRanges does not have to be null or empty, else it will rejected

Parameters:

lodRanges - New ranges of the lod stages

getTexturePack

public TerrainTexturePack getTexturePack()

Returns:

Terrain texturepack that contains all materials of the terrain

setTexturePack

public void setTexturePack(TerrainTexturePack texturePack)

Setting the new texture pack of the terrain

Parameters:

texturePack - New texture pack

getLightMap

public String getLightMap()

Returns:

Lightmap of the terrain that contains the normals for faster lighting calculation

setLightMap

public void setLightMap(String lightMap)

Setting the new light map of the terrain

Parameters:

lightMap - New light map

getHeightMap

public TextureData getHeightMap()

Returns:

The heightmap contains the height at the specific points

setHeightMap

public void setHeightMap(TextureData heightMap)

Setting the new height map of the terrain

Parameters:

heightMap - New height map

getBlendMap

public String getBlendMap()

Returns:

The blend map contains, wich texture should mapped on wich point on the terrain

setBlendMap

public void setBlendMap(String blendMap)

Setting the new blend map of the terrain

Parameters:

blendMap - New blend map

setAmplitude

public void setAmplitude(float amplitude)

Setting the vertical scaling of the terrain in world space.
The terrain max height in world space will be scale * amplitude + y. Can be calculated by Amplitude = (TerrainMaxHeight -TerrainY) / TerrainSize.

Parameters:

amplitude - New terrain vertical scaling in terrain space

getAmplitude

public float getAmplitude()

Returning the current vertical scaling of the terrain in terrain space.
The terrain max height in world space will be scale * amplitude + y.

Returns:

Terrain vertical scaling in terrain space

getTesselationArea

public javax.vecmath.Vector3f getTesselationArea()

Getting the terrains current tesselation area as 3d vector. The x value describes the maximum tesselation, the y value describes the range of the tesselation and the z value describes the tesselation gradient. The formula for the terrain tesselation is:
t(x) = tessFactor * e^-(tessDensity * x)^tessGradient

Returns:

Terrains current tesselation area as 3d vector

setTesselationAttenuation

public void setTesselationAttenuation(float tessFactor,
                                      float tessRange,
                                      float dessGradient)

Setting the terrains current tesselation attenuations. They must be greater than 0, else the change will rejected. The formula for the terrain tesselation is:
t(x) = tessFactor * e^-(tessDensity * x)^tessGradient

Parameters:

tessFactor - New tesselation Factor (Max tesselation)

tessRange - New tesselation density (Range)

dessGradient - New tesselation gradient (Attenuation)
