Method Detail

calculateLod

boolean calculateLod(TerrainPatch terrainPatch,
                     java.util.List<com.jme3.math.Vector3f> locations,
                     java.util.HashMap<java.lang.String,UpdatedTerrainPatch> updates)

clone

LodCalculator clone()

turnOffLod

void turnOffLod()

turnOnLod

void turnOnLod()

isLodOff

boolean isLodOff()

usesVariableLod

boolean usesVariableLod()

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.
