All Implemented Interfaces:

Enclosing class:
WorldMapGenerator
public static class WorldMapGenerator.RoundSideMap
extends WorldMapGenerator
A concrete implementation of WorldMapGenerator that projects the world map onto a shape with a flat top and bottom but near-circular sides. This is an equal-area projection, like EllipticalMap, so effects that fill areas on a map like PoliticalMapper will fill (almost) equally on any part of the map. This has less distortion on the far left and far right edges of the map than EllipticalMap, but the flat top and bottom are probably very distorted in a small area near the poles. This uses the Eckert IV projection. Example map

    • RoundSideMap

      public RoundSideMap()
      Constructs a concrete WorldMapGenerator for a map that can be used to display a projection of a globe onto an ellipse without distortion of the sizes of features but with significant distortion of shape. Always makes a 200x100 map. Uses FastNoise as its noise generator, with 1.0 as the octave multiplier affecting detail. If you were using RoundSideMap(long, int, int, Noise3D, double), then this would be the same as passing the parameters 0x1337BABE1337D00DL, 200, 100, DEFAULT_NOISE, 1.0.

    • RoundSideMap

      public RoundSideMap​(int mapWidth, int mapHeight)
      Constructs a concrete WorldMapGenerator for a map that can be used to display a projection of a globe onto an ellipse without distortion of the sizes of features but with significant distortion of shape. Takes only the width/height of the map. The initial seed is set to the same large long every time, and it's likely that you would set the seed when you call WorldMapGenerator.generate(long). The width and height of the map cannot be changed after the fact, but you can zoom in. Uses FastNoise as its noise generator, with 1.0 as the octave multiplier affecting detail.
      Parameters:
      mapWidth - the width of the map(s) to generate; cannot be changed later
      mapHeight - the height of the map(s) to generate; cannot be changed later

    • RoundSideMap

      public RoundSideMap​(long initialSeed, int mapWidth, int mapHeight)
      Constructs a concrete WorldMapGenerator for a map that can be used to display a projection of a globe onto an ellipse without distortion of the sizes of features but with significant distortion of shape. Takes an initial seed and the width/height of the map. The initialSeed parameter may or may not be used, since you can specify the seed to use when you call WorldMapGenerator.generate(long). The width and height of the map cannot be changed after the fact, but you can zoom in. Uses FastNoise as its noise generator, with 1.0 as the octave multiplier affecting detail.
      Parameters:
      initialSeed - the seed for the GWTRNG this uses; this may also be set per-call to generate
      mapWidth - the width of the map(s) to generate; cannot be changed later
      mapHeight - the height of the map(s) to generate; cannot be changed later

    • RoundSideMap

      public RoundSideMap​(long initialSeed, int mapWidth, int mapHeight, double octaveMultiplier)
      Constructs a concrete WorldMapGenerator for a map that can be used to display a projection of a globe onto an ellipse without distortion of the sizes of features but with significant distortion of shape. Takes an initial seed and the width/height of the map. The initialSeed parameter may or may not be used, since you can specify the seed to use when you call WorldMapGenerator.generate(long). The width and height of the map cannot be changed after the fact, but you can zoom in. Uses FastNoise as its noise generator, with the given octave multiplier affecting detail.
      Parameters:
      initialSeed - the seed for the GWTRNG this uses; this may also be set per-call to generate
      mapWidth - the width of the map(s) to generate; cannot be changed later
      mapHeight - the height of the map(s) to generate; cannot be changed later
      octaveMultiplier - used to adjust the level of detail, with 0.5 at the bare-minimum detail and 1.0 normal

    • RoundSideMap

      public RoundSideMap​(long initialSeed, int mapWidth, int mapHeight, Noise.Noise3D noiseGenerator)
      Constructs a concrete WorldMapGenerator for a map that can be used to display a projection of a globe onto an ellipse without distortion of the sizes of features but with significant distortion of shape. Takes an initial seed and the width/height of the map. The initialSeed parameter may or may not be used, since you can specify the seed to use when you call WorldMapGenerator.generate(long). The width and height of the map cannot be changed after the fact, but you can zoom in. Uses the given noise generator, with 1.0 as the octave multiplier affecting detail. The suggested Noise3D implementation to use is FastNoise.instance
      Parameters:
      initialSeed - the seed for the GWTRNG this uses; this may also be set per-call to generate
      mapWidth - the width of the map(s) to generate; cannot be changed later
      mapHeight - the height of the map(s) to generate; cannot be changed later
      noiseGenerator - an instance of a noise generator capable of 3D noise, usually FastNoise

    • RoundSideMap

      public RoundSideMap​(long initialSeed, int mapWidth, int mapHeight, Noise.Noise3D noiseGenerator, double octaveMultiplier)
      Constructs a concrete WorldMapGenerator for a map that can be used to display a projection of a globe onto an ellipse without distortion of the sizes of features but with significant distortion of shape. Takes an initial seed, the width/height of the map, and parameters for noise generation (a Noise.Noise3D implementation, where FastNoise.instance is suggested, and a multiplier on how many octaves of noise to use, with 1.0 being normal (high) detail and higher multipliers producing even more detailed noise when zoomed-in). The initialSeed parameter may or may not be used, since you can specify the seed to use when you call WorldMapGenerator.generate(long). The width and height of the map cannot be changed after the fact, but you can zoom in. FastNoise will be the fastest 3D generator to use for noiseGenerator, and the seed it's constructed with doesn't matter because this will change the seed several times at different scales of noise (it's fine to use the static FastNoise.instance because it has no changing state between runs of the program). The octaveMultiplier parameter should probably be no lower than 0.5, but can be arbitrarily high if you're willing to spend much more time on generating detail only noticeable at very high zoom; normally 1.0 is fine and may even be too high for maps that don't require zooming.
      Parameters:
      initialSeed - the seed for the GWTRNG this uses; this may also be set per-call to generate
      mapWidth - the width of the map(s) to generate; cannot be changed later
      mapHeight - the height of the map(s) to generate; cannot be changed later
      noiseGenerator - an instance of a noise generator capable of 3D noise, usually FastNoise
      octaveMultiplier - used to adjust the level of detail, with 0.5 at the bare-minimum detail and 1.0 normal
