von-neumann

A little module for generating Von Neumann neighborhoods (i.e. the surrounding cells of a single cell in a grid) of arbitrary range and dimensions.

Inspired by and API-compatible with the moore module.

Installation

npm install von-neumann

Usage

require('von-neumann')(range, dimensions)

Takes two arguments, returning an array of relative coordinates.

  • range determines how large the neighborhood extends, and defaults to 1.
  • dimensions determines how many dimensions the Von Neumann neighborhood covers - i.e. 2 will return the results for a 2D grid, and 3 will return the results for a 3D grid. May be any value above zero.
var vonNeumann = require('von-neumann')
 
// 2D, 1 range:
vonNeumann(1, 2) === [
           [ 0,-1],
  [-1, 0],          [ 1, 0],
           [ 0, 1],
]
