Examples

generateCylinder(width, height, { frequency: 0.04, octaves: 2 })

generateCylinder(width, height, { frequency: 0.06, octaves: 8 })

generateLine(width) // (Replicated across y-axis)

generateLine(width, { frequency: 0.1 }) // (Replicated across x-axis)

generateRectangle(width, height)

generateRectangle(width, height, { frequency: 0.04, octaves: 8 })

API

Options

The options object for each generate function contains the following properties:

• amplitude?: number – Defaults to 1.0
• frequency?: number – Defaults to 1.0
• octaves?: number – Defaults to 1
• persistence?: number – Defaults to 0.5

generateCylinder (circumference: number, height: number, options: Options = {}): Uint8Array[]

Generates a two-dimensional noise field formed around a three-dimensional cylinder, such that it is continuous across the x-boundaries.

generateLine (length: number, options: Options = {}): number[]

Generates a one-dimensional noise field.

generateRectangle (width: number, height: number, options: Options = {}): Uint8Array[]

Generates a two-dimensional noise field isolated to width and height (non-continuous noise).
