Class FaultHeightMap

All Implemented Interfaces:

public class FaultHeightMap extends AbstractHeightMap
Creates a heightmap based on the fault algorithm. Each iteration, a random line crossing the map is generated. On one side height values are raised, on the other side lowered.
  • Field Details


      public static final int FAULTTYPE_STEP
      Values on one side are lowered, on the other side increased, creating a step at the fault line
      See Also:

      public static final int FAULTTYPE_LINEAR
      Values on one side are lowered, then increase linearly while crossing the fault line to the other side. The fault line will be an inclined plane
      See Also:

      public static final int FAULTTYPE_COSINE
      Values are lowered on one side, increased on the other, creating a cosine curve on the fault line
      See Also:

      public static final int FAULTTYPE_SINE
      Value are lowered on both side, but increased on the fault line creating a smooth ridge on the fault line.
      See Also:

      public static final int FAULTSHAPE_LINE
      A linear fault is created
      See Also:

      public static final int FAULTSHAPE_CIRCLE
      A circular fault is created.

  • Constructor Details

    • FaultHeightMap

      public FaultHeightMap(int size, int iterations, int faultType, int faultShape, float minFaultHeight, float maxFaultHeight, long seed) throws Exception
      Constructor creates the fault. For faultType other than STEP, a range can be provided. For faultShape circle, min and max radii can be provided. Don't forget to reload the map if you have set parameters after the constructor call.
      size - The size of the heightmap
      iterations - Iterations to perform
      faultType - Type of fault
      faultShape - Shape of the fault -line or circle
      minFaultHeight - Height modified on each side
      maxFaultHeight - Height modified on each side
      seed - A seed to feed the Random generator

    • FaultHeightMap

      public FaultHeightMap(int size, int iterations, float minFaultHeight, float maxFaultHeight) throws Exception
      Create a heightmap with linear step faults.
      size - size of heightmap
      iterations - number of iterations
      minFaultHeight - Height modified on each side
      maxFaultHeight - Height modified on each side
  • Method Details

    • load

      public boolean load()
      Description copied from interface: HeightMap
      load populates the height map data. This is dependent on the subclass's implementation.
      true if the load was successful, false otherwise.
