triangle-random-pts

generates uniformly distributed random points in a 3d triangle

generated points can either be random (via Math.random) or quasi-random using Martin Robert's R₂ sequence

Installation

npm i triangle-random-pts

Usage

var trp = require('triangle-random-pts');

//triangle is 3 pts [x,y,z]
var triangle = [[0,0,1],[1,0,1],[1,1,1]];

var numberOfPoints = 10;
var pointsRandom = trp.randomPointsInTriangle(triangle,numberOfPoints);
var pointsQuasiRandom = trp.quasiRandomPointsInTriangle(triangle,numberOfPoints);

console.log(pointsRandom);
console.log(pointsQuasiRandom);
