fog

Fog {
  exposedField SFColor  color            1 1 1
  exposedField SFString fogType          "LINEAR"
  exposedField SFFloat  visibilityRange  0
  eventIn      SFBool   set_bind
  eventOut     SFBool   isBound
}

• A bindable node!
• Does not fog background node so don't combine them
• Can be expensive to draw and will slow frame rate
• Use black fog for depth cueing
• Use blueish fog for underwater scenes
• Combine with visibilityLimit field of navigationInfo node to fade distant objects in smoothly
• Linear or Exponential fog is possible, linear is faster but less realistic
