TerrainNoise

Remarks

Value noise rather than gradient noise, for the reason [docs/plan/26] gives for the camera's shake: the range of value noise is exactly the range of its lattice, so an amplitude declared as three metres never exceeds three metres. A gradient-noise peak is a number you look up and hope for, and an artist sculpting near a building cannot work with "three metres, except occasionally".

Fields and properties (6)

• public int Octaves

  How many layers of detail.

• public float Frequency

  How many samples one period of the coarsest octave spans, inverted.

• public float Lacunarity

  How much finer each octave is than the last.

• public float Gain

  How much quieter each octave is than the last.

• public bool Ridged

  Whether to fold the noise about zero, which makes ridges instead of hills.

• public uint Seed

  What the lattice derives from.

Methods (2)

• public TerrainNoise(int Octaves = 4, float Frequency = 0.02, float Lacunarity = 2, float Gain = 0.5, bool Ridged = false, uint Seed = 2654435769)

  The shape of the noise the Noise tool adds.

• public float At(int x, int z)

  The noise at a sample, in −1…1 — or 0…1 when Ridged.
