Comet Tails

Rosettas for us all

The CometTails { } subnode is a part of Kopernicus Expansion and allows you to add Dust and Ion trails to bodies.

Example

This is the default configuration, except for the type.

Body
{
  CometTails
  {
    CometTail
    { 
      type = Ion
      color = 1,1,1,1
      rimPower = 1.41
      distortion = 0.143
      alphaDistortion = 0.262
      zDistortion = 0.12
      frequency = 0.1547
      lacunarity = 0.1518
      gain = 0.734
      radius = 2000
      length = 16000
      opacityCurve
      {
        key = 0 0.6
        key = 5E9 0.45
        key = 1.25E10 0.1
        key = 2E10 0.0075
        key = 3E10 0
      }
      brightnessCurve
      {
        key = 0 1
        key = 5E9 0.4
        key = 1.25E10 0.09
        key = 2E10 0.0075
        key = 3E10 0
      }
    }
  }
}

Property	Format	Description
type	CometTailType	The type of comet tail. The possible values are `Ion` and `Dust`.
color	Color	The color of the tail. Default is white. NOTE: Alpha value does not matter.
rimPower	Single	How close the tail rim stays to the edge of the body. The higher the number, the closer it is. Default is 1.41.
distortion	Single	The distortion of the tail. Default is 0.143.
alphaDistortion	Single	The transparency distortion of the tail. Default is 0.262.
zDistortion	Single	? Default is 0.12
frequency	Single	The frequency of the comet tail’s noise. Default is 1.547
lacunarity	Single	The lacunarity of the comet tail’s noise. Default is 1.518.
gain	Single	? Default is 0.734.
radius	Single	The radius of the teardrop that makes up the comet tail. Default is 2000.
length	Single	The length of the comet tail. Default is 16000.
opacityCurve	FloatCurve	A curve that associates a distance value with an opacity value from 0 to 1?
brightnessCurve	FloatCurve	A curve that associates a distance value with a brightness value.
