2.4.9.6 No_Shadow

You may specify the no_shadow keyword in an object to make that object cast no shadow. This is useful for special effects and for creating the illusion that a light source actually is visible. This keyword was necessary in earlier versions of POV-Ray which did not have the looks_like statement. Now it is useful for creating things like laser beams or other unreal effects. During test rendering it speeds things up if no_shadow is applied.

Simply attach the keyword as follows:

  object {
    My_Thing
    no_shadow
  }
