Public Property QuadraticAttenuation As Single

Property Value

Single

float

The quadratic portion of the attenuation equation that determines how the light falls off with distance. Controls light intensity falloff based on distance squared. Range is from 0 to infinity.

Examples

_pointLight.QuadraticAttenuation = .0007F;

Remarks

The PointLight.QuadraticAttenuation property is part of the attenuation equation which also includes PointLight.LinearAttenuation and PointLight.ConstantAttenuation:

1/(Constant+Linear*(Distance/100)+Quadratic*(Distance/100)*(Distance/100))
