public void write(com.jme3.export.JmeExporter ex)
           throws java.io.IOException

Specified by:

write in interface com.jme3.export.Savable

Throws:

java.io.IOException

read

public void read(com.jme3.export.JmeImporter im)
          throws java.io.IOException

Specified by:

read in interface com.jme3.export.Savable

Throws:

java.io.IOException

usesVariableLod

public boolean usesVariableLod()

Description copied from interface: LodCalculator

If true, then this calculator can cause neighbouring terrain chunks to have LOD levels that are greater than 1 apart. Entropy algorithms will want to return true for this. Straight distance calculations will just want to return false.

Specified by:

usesVariableLod in interface LodCalculator

getPixelError

public float getPixelError()

setPixelError

public void setPixelError(float pixelError)

setCam

public void setCam(com.jme3.renderer.Camera cam)

turnOffLod

public void turnOffLod()

Specified by:

turnOffLod in interface LodCalculator

isLodOff

public boolean isLodOff()

Specified by:
