p5.func Example: p5.Gen Direct Evaluation

// create a variable to store function generator object

var g;

​

function setup(){

  // function generator object

  g = new p5.Gen();

  // harmonics(x, [h1… hn]): periodic function of harmonic strengths defined by an Array passed as the second argument. x is 0 to 1. Returns f(x).

  // evaluate the value 20% (0.2) into a wavetable 

  // defined by harmonic strengths 1., 0.5, and 0.3:

  var a = g.harmonics(0.2, [1.0, 0.5, 0.3]);

  console.log(a);

​

  // breakpoint function of line segments defined in time, amplitude pairs in the Array passed as the second argument. x is 0 to 1. returns f(x).

  // evaluate the value halfway (0.5) into a breakpoint function 

  // rising from 0 to 1 then falling to 0:

  var b = g.bpf(0.5, [0, 0, 1, 1, 2, 0]);

  console.log(b);

  // window(x, type, args): generates window functions by type. Some functions have optional args. x is 0 to 1. Returns f(x). 

  // evaluate the value 3/4ths (0.75) into a hamming window function:

  var c = g.window(0.75, "hamming");

  console.log(c);
