Expand description

Sets the default ambient and directional light. The defaults are ambientLight(128, 128, 128) and directionalLight(128, 128, 128, 0, 0, -1). Lights need to be included in the draw() to remain persistent in a looping program. Placing them in the setup() of a looping program will cause them to only have an effect the first time through the loop.

Examples

function setup() {
  createCanvas(100, 100, WEBGL);
}
function draw() {
  background(0);
  lights();
  rotateX(millis() / 1000);
  rotateY(millis() / 1000);
  rotateZ(millis() / 1000);
  box();
}
