Render3D. DirectionalLight3D

DirectionalLight3D - A Light3D that shines from far away with no falloff, like sunlight

  • It shines from its position toward the origin, like a three.js DirectionalLight: only the direction to it counts, so moving it or its parent swings the light around; parent it to a sun in the sky and it follows
  • It cannot sit on the origin, since that leaves no direction
  • Like every Light3D it casts no shadow and makes no highlight, only the sun, render3D.sunDirection, does

Constructor
