DirectionalLight

WHS.DirectinalLight creates a light that shines from a specific direction not from a specific position.

This light will behave as though it is infinitely far away and the rays produced from it are all parallel.

The best analogy would be a light source that acts like the sun: the sun is so far away that all sunlight hitting objects comes from the same angle.

It has the same options as WHS.AmbientLight in light paramater, but it also supports pos and target paramaters.

new WHS.DirectionalLight( {
  light: {
    color: 0xffffff,
    intensity: 0.2
  },

  position: [10, 20, 10]
}).addTo(world);

📘
This light will fall down from vec3(10, 20, 10) to vec3(0, 0, 0)
