Noise

Inherits: Resource < RefCounted < Object

Inherited By: FastNoiseLite

Abstract base class for noise generators.

Description

This class defines the interface for noise generation libraries to inherit from.

A default get_seamless_image implementation is provided for libraries that do not provide seamless noise. This function requests a larger image from the get_image method, reverses the quadrants of the image, then uses the strips of extra width to blend over the seams.

Inheriting noise classes can optionally override this function to provide a more optimal algorithm.

Methods

Method Descriptions

Image get_image(width: int, height: int, invert: bool = false, in_3d_space: bool = false, normalize: bool = true) const 🔗

Returns an Image containing 2D noise values.

Note: With normalize set to false, the default implementation expects the noise generator to return values in the range -1.0 to 1.0.

Array[Image] get_image_3d(width: int, height: int, depth: int, invert: bool = false, normalize: bool = true) const 🔗

Returns an Array of Images containing 3D noise values for use with ImageTexture3D.create.

Note: With normalize set to false, the default implementation expects the noise generator to return values in the range -1.0 to 1.0.

float get_noise_1d(x: float) const 🔗

Returns the 1D noise value at the given (x) coordinate.

float get_noise_2d(x: float, y: float) const 🔗

Returns the 2D noise value at the given position.

float get_noise_2dv(v: Vector2) const 🔗

Returns the 2D noise value at the given position.

float get_noise_3d(x: float, y: float, z: float) const 🔗

Returns the 3D noise value at the given position.

float get_noise_3dv(v: Vector3) const 🔗

Returns the 3D noise value at the given position.

Image get_seamless_image(width: int, height: int, invert: bool = false, in_3d_space: bool = false, skirt: float = 0.1, normalize: bool = true) const 🔗

Returns an Image containing seamless 2D noise values.

Note: With normalize set to false, the default implementation expects the noise generator to return values in the range -1.0 to 1.0.

Array[Image] get_seamless_image_3d(width: int, height: int, depth: int, invert: bool = false, skirt: float = 0.1, normalize: bool = true) const 🔗

Returns an Array of Images containing seamless 3D noise values for use with ImageTexture3D.create.

Note: With normalize set to false, the default implementation expects the noise generator to return values in the range -1.0 to 1.0.
