  The light source positional entity is a subtype of light source.

  Illumination of a point light falls off with distance as specified by three attenuation coefficients. 
  The attenuation factor is
  ⪯
  1/max(attenuation[0] + attenuation[1] × r + attenuation[2] × r 2 , 1),

  where r is the distance from the light to the surface being illuminated. The default is no attenuation. 
  An attenuation value of (0, 0, 0) is identical to (1, 0, 0). Attenuation values is greater than or equal to zero.
