The listed density functions compute their respective mathematical functions.

{
  "type": "lithostitched:sin",
  "argument": 5
}

• argument: The input density function.

The axis density function computes the current position on the given axis.

{
  "type": "lithostitched:axis",
  "axis": "x"
}

• axis: The axis to get the position from.

The mix density function smoothly transitions between argument1 and argument2 using input as the delta between them.

{
  "type": "lithostitched:mix",
  "input": "minecraft:overworld/depth",
  "argument1": "something:on_the_surface",
  "argument2": "something:deep_underground"
}

• input: The input argument.
  • If computes to (-∞,0], returns argument1
  • If computes to [1,∞), returns argument2

The shift density function shifts the computed position

{
  "type": "lithostitched:shift",
  "input": "minecraft:overworld/depth",
  "shift_x": 15,
  "shift_y": 0,
  "shift_z": 15
}

• input: The input argument.
• shift_?: The density function to shift the input by on the ? axis.

The select density function selects a density function to compute based on the given input function

{
  "type": "lithostitched:select",
  "input": "minecraft:overworld/depth",
  "fallback": 0,
  "selections": [
    {
      "range": [
        -2,
        -1
      ],
      "function": "my_mod:high_skies"
    },
    {
      "range": [
        1,
        2
      ],
      "function": "my_mod:deep_depths"
    }
  ]
}

• input: The input density function.
• fallback: The fallback density function to compute if no objects in selections match.
• selections: A list of selection objects.
  • range: The double range (e.g. 0.1, [-0.1,0.1]) the input output must resolve to in order to select this object's function.
  • function: The density function to compute if the selection is chosen.

The fast_noise density function samples a fast noise config object.

{
  "type": "lithostitched:fast_noise",
  "config": "lithostitched:region/overworld",
  "xz_scale": 1,
  "y_scale": 0,
  "shift_x": "lithostitched:region/shift_x",
  "shift_z": "lithostitched:region/shift_z"
}

• config: The fast noise config to sample.
• xz_scale: The scale of the noise on the x and z-axes, as a double. Defaults to 1.
• y_scale: The scale of the noise on the y-axis, as a double. Defaults to 1.
• shift_?: The shift on the ? axis, as a density function. Defaults to a constant 0.
