.NET Syntax

Visual Basic (Declaration) 
Property IndexOfRefraction As Double
Visual Basic (Usage) 
Dim instance As IRenderMaterial
Dim value As Double
instance.IndexOfRefraction = value
value = instance.IndexOfRefraction
double IndexOfRefraction {get; set;}
property double IndexOfRefraction {
   double get();
   void set (double value);

Return Value

Index of refraction


This property controls the bending of light as it passes through a transparent object. Although actually dependent on the ratio of indices between the transparent material entered and the material exited, in practice, the higher the index of refraction, the more the light is bent. Typical values are 1.0 for air, 1.33 for water, and 1.44 for glass.
