    SpotExponent Property
    In This Topic
    The spot exponent specifies the intensity distribution of a spot light.
    Syntax
    'Declaration
 

    Public Property SpotExponent As System.Single
    'Usage
 

    Dim instance As NSpotLightSource
Dim value As System.Single
 
instance.SpotExponent = value
 
value = instance.SpotExponent
    public System.float SpotExponent {get; set;}
    Remarks
    All values are automatically clamped in the range [0,128]. Effective light intensity is attenuated by the cosine of the angle between the direction of the light and the direction from the light to the vertex being lighted, raised to the power of the spot exponent. Thus, higher spot exponents result in a more focused light source. The default spot exponent is 0, resulting in uniform light distribution.
