OpenSimplex

✓ from opensimplex import OpenSimplex

Generate 2D noise and display with matplotlib.

from opensimplex import OpenSimplex import matplotlib.pyplot as plt seed = 42 gen = OpenSimplex(seed=seed) size = 10 noise = [[gen.noise2d(x / size, y / size) for x in range(size)] for y in range(size)] plt.imshow(noise, cmap='gray') plt.show()

Debug

Known issues

breakingIn v0.4+, API changed from function-based (`opensimplex.noise2d(x, y)`) to class-based (`OpenSimplex` object). Old `opensimplex.noise2d` etc. no longer exist.

fix

Use `from opensimplex import OpenSimplex` and create an instance: `gen = OpenSimplex(seed=...)` then call `gen.noise2d(x, y)`.

affects: >=0.4

deprecatedDirect module-level functions `opensimplex.noise2d`, `opensimplex.noise3d`, `opensimplex.noise4d` are removed. Use the class-based API.

fix

Replace `opensimplex.noise2d(x, y)` with `OpenSimplex(seed).noise2d(x, y)`.

affects: >=0.4

gotchaThe `seed` parameter must be an integer. Passing a non-integer (e.g. string) may cause TypeError or unexpected behavior.

fix

Always pass an integer seed: `OpenSimplex(seed=42)`.

affects: all

gotchaOpenSimplex noise output range is approximately [-1, 1], but not guaranteed to hit exactly -1 or 1. Scaling to [0,1] often done via `(noise + 1) / 2`.

fix

If you need a [0,1] range, apply: `value = (noise + 1) / 2`.

affects: all

Errors

Common errors & fixes

AttributeError: module 'opensimplex' has no attribute 'noise2d'

Using old function-based API after upgrading to v0.4+.

fix

Use class-based API: `from opensimplex import OpenSimplex; gen = OpenSimplex(seed=0); gen.noise2d(x, y)`.

TypeError: 'int' object is not callable

Accidentally assigned `opensimplex` to an integer variable or overwritten the import.

fix

Do not reuse the name `opensimplex` as a variable. Use a different name for the instance.

ValueError: seed must be an integer

Passing a non-integer seed (e.g., float or string) to OpenSimplex constructor.

fix

Ensure seed is an integer: `OpenSimplex(seed=int(seed_value))`.
