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.

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 Image\ s 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 Image\ s 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.
