Lighting the environment
Using point light attenuation

  • Point light rays are attenuated:
  • As distance increases, light brightness decreases

  • Attenuation is controlled by three coefficients:
  • constant, linear, and quadratic

    • brightness =
    lightIntensity
    constant + linear*distance + quadratic*distance2
