flow-field

A library for generating flow fields.

Resources for learning more about flow fields and noise:

import {generateField} from '@romellogoodman/flow-field';

const field = generateField({count: 100, height: 1000, width: 1000});

Creates the particles for a flow field.

@param {Number} count Number of particles in the field.
@param {Number} height Height of space.
@param {Number} margin Percent of height/width to create a padding.
@param {String} seed Random (random-js) seed.
@param {Number} width Width of space.
@return {Array} List of particle objects containing the starting x and y coordinates.

Computes the new position for a particle and adds it to the particle.line array.

@param {Number} amplitude Controls the range of values we get from the noise function.
@param {Number} damping Slows down the particle (think friction).
@param {Number} frequency Controls how quickly/slowly the noise function is "evolving over time".
@param {Number} lengthOfStep Amount to move the coordinate.
@param {Object} particle Particle object containing the.
@return {Void} Operates on the particle and returns nothing.

Creates a flow field with particles and lines.

@param {Number} amplitude Controls the range of values we get from the noise function. Default to 5.
@param {Number} count Number of particles in the field. Default to 1000.
@param {Number} damping Percentage that slows down the particle (think friction). Default to 0.1.
@param {Number} height Height of space.
@param {Number} margin Percent of height/width to create a padding. Default to 0.1.
@param {Object} particles List of particles to use instead of generating them.
@param {String} scale Used to compute frequency, number of steps and step length. Default to 1.
@param {String} seed Random (random-js) seed.
@param {Number} width Width of space.
@return {Array} List of particle objects containing the line coordinates.
