InheritanceFresnelPBMaterial Inheritance away3d.materials.SinglePassShaderMaterial

BitmapData material which creates reflections based on a cube map. The reflection strength changes based on the refraction of the material and its environment, as well as the angle of view. This can be used to create water-like reflections.


Public Properties

  envMapAlpha : Number
The opacity of the environment map, ie: how reflective the surface is.
FresnelPBMaterial
  exponent : Number
The exponent of the calculated fresnel term.
FresnelPBMaterial
  innerRefraction : Number
The refractive index of the inner medium (ie the material itself)
FresnelPBMaterial
  outerRefraction : Number
The refractive index of the outer medium (where the view ray starts)
FresnelPBMaterial
  refractionStrength : Number

Property Detail
envMapAlphaproperty
envMapAlpha:Number

The opacity of the environment map, ie: how reflective the surface is. 1 is a perfect mirror.


Implementation
    public function get envMapAlpha():Number
    public function set envMapAlpha(value:Number):void
exponentproperty 
exponent:Number

The exponent of the calculated fresnel term. Lower values will only show reflections at steeper view angles.
